Sea To Summit - Ether Light Series

The ether light XR is the first pad that’s given me just as good a night sleep as I do at home. It’s such a comfortable pad. I’m a side sleeper and nothing compares to it for comfort for me. It can be a bit noisy so when I’m tossing and turning before falling asleep it can be a bit of a nuisance but it’s never hindered my sleep

It’s not crinkly or rustly, can be a bit squeaky! But think it also depends on sleeping bag material. Like I said it’s never cause me an issue but my partner has commented on it before

If comfort is a priority, you’ll do no better than the new Sea To Summit Ether Light XR.

I'm a side sleeper and I find the etherlight XT really comfortable. It creeks and croaks like crazy though so anyone you go with will hate you. And no, it doesn't go away. People say that but they are lying lol. I think they just got used to it.

Exped Dura. It has down. I have the 6R LW. You can get a slightly lighter version which is lighter due to thinner face fabrics. Avoid StS Etherlight XT at all costs, as I have had two getting pinctures where the dividers attach. Constant flats from just lying on them. And I am not the only one. This is why I bought the Exped Dura.

Sharing cause I grabbed one - if anyone's looking Sea to Summit is dumping old inventory and the Ether Light XT Extremes that are still available are 40% off.

I tried the r-3.2 model, found it too cold. Exchanged it for the womans model, which has a slightly higher 3.5 r-value, and also found it too cold. (This was during spring trips at sea level.) I have not had this problem with other pads with roughly those r-values. There’s just something about the design of the old model, down insulation plus cold spots, that makes it sleep colder than the r-value would suggest. At least for me.

I am a 181cm, 100kg side sleeper and just bought the S2S Etherlight XR. It arrived this morning and my [**first impressions are here.** ](https://www.reddit.com/r/Ultralight/comments/1isa5ot/comment/mdq8c2p/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)

Auspost delivered a new S2S Etherlight XR (regular Mummy) this morning so I set it up next to my old Thermarest Xtherm (2020 model) - Here are my first impressions. **Comfort** \- It feels more comfortable than my Xtherm. At 10cm thick it is much more plush. **Size/shape** \- The extra 4cm in width feels good. I am a 181cm, 100kg side sleeper and this feels like a better size and shape for me. It is also wider near the foot which is very welcome. **Profile** \- the Etherlight is higher at the sides than in the middle which feels a lot more stable. The Xtherm with its horizontal baffles regularly made me feel as though I was about to roll off the side. **Noise** \- They are roughly the same in volume but it is a different sound. The Xtherm sounded like a muted chip packet - still crinkly but not as noisy as the old Xlite. The Etherlight sounds more like a thick balloon - still makes a noise but a lower pitch. **Weight** \- Heavier. On my scales the Xtherm is 440g. S2S was 481g. **Warmth** \- The design looks pretty good. The new Etherlight uses reflective aluminium film - similar to the thermarest. The welds use a loop in the centre so it maintains an air gap even at the weld. Will actually take a few nights outside to really tell. I am not expecting it to be as warm as my old mat but we shall see. **Slipperyness** \- The fabric feels a little more grippy than the Xtherm so hopefully won't slip around as much. Once again - will need a few nights in the outdoors to really tell. **Packability -** Great. It folds down to same size as the Xtherm. I believe is a great improvement over the old Etherlight XT due to the new insulation. So on most points the Etherlight looks to be a winner. Size, shape and comfort is great. Weight is a bit higher and warmth is TBD but I feel like this is going to be my main mat form here on.

I tried both and went with the Ether Light XR. It came down to what felt good. I didn’t think the baffle design on the Tensor AS was comfortable or distributed weight well and much preferred the baffling on the Ether Lite as a side/stomach sleeper. I plan on upping the R value with a Z-lite pad if necessary.

The Ether Light is woven nylon just like the Nemo, but 30D vs 20D for the top. I compared them back in May, but I remember they felt fairly similar material-wise. I did think the Nemo was slightly more crinkly. The Ether Light is a little slippery, but I think it makes it easier to flip around. My last pad was a polyester Exped Dura which had a lot of friction going on with my clothes, which made it annoying to flip around at night because my clothes and quilt would get bunched up and twisted.

No problem! It was one of the reasons I switched pads. The other was that I didn’t find vertical baffles all that great for side sleeping. The arm I slept on frequently went numb, and I’m pretty sure it was from the baffles pressing against it.

I’ll second the XR. It’s pretty comfy for stomach/side sleeping. But also, I tried out the NeoLoft at REI this weekend and holy crap is it a comfy cradle of air.

I’m 100% co-signing this review. As a rotisserie chicken sleeper who likes to be tucked in, I effing love my Zenbivy and how snuggleable it is. It really does feel like a real bed. I also recently got the Ether Light XR to pair with it! I was also considering the Zenbivy Flex, but the S2S warranty won out. I was dead set on a rectangular pad but S2S’s pricing structure is kind of nonsensical, making the large tapered cheaper than the rectangular regular/wide. The taper didn’t bother me like I thought it would since it starts past my hips, and the longer length meant I could stretch out on my stomach without my feet hanging off. I also prefer the air sprung cell construction over the vertical baffles on my previous Exped pad. I think they distribute my weight better. I do agree that it’s a bit plasticky, but my Zenbivy sheet makes that a nonissue for me.

The sea to summit is 10cm thick, which is amazing for it's size and weight. But it's made of a noisy fabric

When I did Baker I brought a closed cell pad (Nemo switch back) and an inflatable (Sea to summit) for comfort and redundancy. You'll be hard pressed to find a new bag that's also lightweight for $200. You'll probably need to see if you can find something used or I would recommend you see if you can rent one.

If it’s rare, yes. However I feel like failing welds is becoming more common with new baffle designs, and I don’t want to through the hoops of buying and then returning gear all the time, and I especially don’t need it failing on me when I’m in the middle of the woods. I wouldn’t want a tent that might not be waterproof just because it has a warranty. It’s actually worse because you could test a tent right away whereas that poorly designed sleeping pad might need a good deal of use to expose its weakness. Maybe I’m off base here, just going based off posts I’ve read while trying to upgrade my sleeping pad (ended up returning the etherlight xt extreme)

Oh yeah it’s nonsense lol. I’m so confused honestly. I got it before the R value standardization made a scandal out of it. I knew it wouldn’t be as warm as its stated r value, but found it warm enough down to around 34F on its own. If I found a lighter pad with baffles like that I’d try it. Used to have a thermarest with horizontal baffles, got hip pain. Ccf pad, hip pain. Tried the new quilted air spring baffles that everyone is raving about in the form of the etherlight, still got hip pain. The etherlight I would have returned anyway though as I found it to be the equivalent warmth of the insulated static v plus my ccf, and even pairing the etherlight extreme with a ccf, and having it fully inflated wasn’t nearly enough for sleeping on frozen ground or snow. Having a hefty pad that’s neither warm nor comfortable was just unacceptable for a $180 (on sale) pad. So for now I’ll alternate between the klymit and my hammock lol

I hope the etherlight works for you. I’d get it from Rei in case you need to return it. I returned mine as the extreme version wasn’t nearly warm enough to justify the price and weight. I’d have put up with that if it was super comfortable but I found that it hurt my hips even when I let out a bunch of air (which compromised the r value even more). I was really bummed about it all. Thought I’d found my holy grail pad

Picked up a S2S Etherlight XR and had my first 4 days on it recently. Super comfy, even as a side sleeper.

Sea to summit etherlight xr is very comfortable for a side sleeper as well, while not being too heavy or bulky.

Ended up getting a couple sea to summit mats on sale for $60.

Big Agnes and sea to summit checks all your boxes. Small/compact, uses vertical baffles to prevent that bouncy castle feeling and provide actual support

Rapide sl is peak. My favorite pad. Ive got a sea so summit pad that i love too but can't remember the name of it. It has like a 7 or 8 r value tho.

Self-inflating foam mats seem like a good middle ground. I hadnt seen the nemo flyer. Looks very similar to the new sea to summit pursuit self-inflating that i just got (5cm thick, 600g). It's extremely comfortable and i cant wait to try it out, after getting zero sleep on my etherlight xt recently. Do you have the zlite for extra padding, or for extra warmth?

Ive used the sts ether light xt and the ba zoom ul, and the zoom ul is more comfortable for a side sleeper imo. Not sure if the xr is much better than the xt

I love my Ether Light highly recommend and from what I've heard there warranty is exceptional. I went with the XT Insulated req wide amazing sleeps on it.

Sea to Summit Ether Light XT Insulated and Nemo Tensor are both widely regarded as The most comfortable pads. I have or tried both and they're great.

So that's why their XT pads have been on sale for the last few months. I finally snagged myself a short version after waiting over a year for a sale.

Get something with a super high R rating - higher than you think you need. Look for a baffling system that is either dimpled or vertical. For whatever reason, horizontal baffles don’t have a lot of “give” to them so they are less comfortable for side sleepers in general.  Therm-a-Rest Neoair Xtherm is probably the warmest pad out there (not the highest R rating per se but the most effective insulation system means it is still warmer than other pads with higher R values). It may not the most comfortable for a side sleeper because of the horizontal baffles, however. But this is the pad you want if you want to prioritize warmth. If you want to prioritize comfort, Sea to Summit Ether Light XR Pro will probably not sleep as warm but will be more comfortable for a side sleeper because of the dimpled baffling system. Nemo Tensor Extreme Conditions is also very warm and only slightly less comfy than the Ether Light.  Exped Ultra 7R is a bit heavier and bulkier but is very comfy for a side sleeper. It uses down rather than reflective film for insulation. So it won’t be quite as crinkly as a lot of warm pads, but I’m not sure if the down insulation is more or less effective in this application.  Big Agnes Campmeister Deluxe is quite bulky and heavy for a backpacking pad but is super, super comfortable and has a very respectable R value of 7.  The other big, bulky “luxury” comfort backpacking pads - Exped Megamat Ultra and Therm-a-Rest Neoloft - are great options for comfort but with lower R values so they may be less warm than you might want.  Other things to consider - even a well-insulated sleeping pad will only stay as warm as your body is able to heat it. The bigger the pad, the more of your body’s heat it will draw away from you. So don’t buy a massively oversized sleeping pad thinking it will automatically be more comfortable. For insulating purposes, something that is only as big as you need it to be will be more efficient for your body to keep warm.  Make sure you take advantage of all the usual strategies for staying warm in the backcountry: Use your Nalgene as a hot water bottle and keep it in your sleeping bag/quilt with at night. Do some jumping jacks or other activity to get your heartrate and body temperature up before going to bed. Make sure you are properly hydrated and getting enough food to keep warm. Etc. 

Nemo Tensor Extreme Conditions will be warmer than the All Season.  I find the Tensor series to be a bit more comfortable than the NeoAirs. But she’s already uncomfortable with the Tensor. I would consider instead the Sea to Summit Ether Light XR Pro, which has a high R value and most people have found to be more comfortable than either the Tensors or the NeoAirs. 

Just used my Helix last night and would recommend. To me it’s much comfier than than the Sea to Summit Ether Light XT I had before

StS Ultralight Insulated. Anything packable with R value about 3 should be OK.

His findings pretty much match my experiences. I have a S2S etherlight insulated. It's so cold with a quilt, It really feels like it's doing nothing, even in summer conditions. Comfortable though.

Im not sure if I can trust S2S with another pad after my freezing XT. Comfort counts for nothing if using a quilt and you're cold.

Check out the new Sea to Summit XR Pro, it’s got a 7.4 R-value, which is actually warmer than the XTherm’s 7.3. I find the baffle design way more comfortable than Thermarest, and the mummy version is a bit wider too, and it’s thicker.

I just got the updated Sea to Summit Ether Light XR and can't wait to give it a proper test run next weekend. It was super comfy on my living room floor. Comes in a few 25" wide options. If you need higher R value, there's the pro version which is 4-season.

I'd give it a 9/10. Very comfy, great packed size, teeny bit heavier than I'd want (but comfort totally justified it). There were a couple cold spots but the pad had deflated as the temp dropped, so I just topped it off and all was well.

I personally think Sea to Summit pads are comfortable.  Nemo Tensor might interest you as well. 

Oh totally. It went great! I had a 25° western mountaineering bag and temps were 39° on my thermometer the first night. The pad was great. No cold spots. For reference I slept terribly and was cold in 37° on a rapide pad in December last year. It could have also been the quilt I was using. I had zero issues with the pad and it was of course very comfortable. 

\+1 for the Ether Lite! I've got a bunch of pads, but I always end up going back to this one for comfort. The material is a little squeaky and I would trust it below freezing, but it's very comfortable. I've also seen it on sale regularly for less than $150.

The new SeatoSummit XR Pro pads might be a good option. They seem to have really improved on the size/weight, and have around a 7 r-value. I have one of their older XT non-pro models and find it really comfortable.

I own all the pads you have listed, I would go with the Tensor All Season. You might also take a look at the new XR version of the Ether Light. I believe they updated this version with a more traditional mylar style insulation resulting in better weight and a higher R-Value. If it's anywhere near the comfort of the old version, it would be a solid option. You might also look at pairing any potential pads with something like the Gossamer Gear thinlight. It would add quite a bit of protection with around an additional 0.5 R-Value.

Pad. The ul pick for high comfort is the s2s ether light xt

Some folks don't, especially if they're back sleepers. The s2s is thicker and seems more popular with side sleepers

The neoloft is about 40% heavier than the ether light xt and the megamat weight nearly twice as much. I don't think either of them are ul as even the ether light xt sacrifices quite a bit of weight compared to the neoair. UL is about sacrifices. What is the lightest pad you can sleep on? If that's the megamat then that's what it is for you, but if you could sleep on a neoair and you want a megamat because it's comfortable, you're carrying 24 oz you don't need. The ether light xt comes in at just over a lb in the women's size. There's no 4+ inch pad that can match or beat that weight AFAIK. Other pads are more comfortable but they're heavier.

I have a previous back injury. I find the Womens S2S Etherlight to be the most comfortable, though the least warm. Next for comfort is the Nemo All Season, as well as the Nemo Tensor. In comfort, they are both just slightly less comfortable than the S2S. Both are warmer than the S2S. I have used the ExPed Hyperlight pad for about 40 nights. I believe this pad has been replaced with the newer version. Mine was a 2.8R value. For me, the warmth was equal to the S2S pad. It was not an uncomfortable pad. It just wasn't as comfortable as the S2S and Nemo pads. I tried the Thermarest NeoAir Xlite. My lower back ached when I used the pad. It just didn't have the support I needed. I wish I could use it as it has great warmth to weight ratios. I used the wide versio pads for each of these, though the Exped was a mummy MW version I would assume what is comfortable for me may not translate to you as your back injury may be different than mine. My injury involved the lower back. I have slept in a hammock a few nights and never experienced back pain.

If I need more than 4 R insulation (I'm sleeping on snow most likely) I'm taking a ccf for backup because I don't want to die. After stacking both pads there is no need for more than 4 R. However, my insulated sea to summit pad with 4R is about the same weight as the Light Tour pad you tested.

Sea to summit has a lifetime guarantee on their products which ultimately became my deciding factor in choosing them between the same two pads you mentioned.

I LOVE the XT R factor (7.1?) the warmth factor definitely has me considering quits over bags now.

Oh-You’re right, my mistake! I just can’t believe how comfortable it is! I’m an old school double closed cell foam pad user and it doesn’t make sense now to use ANYTHING else. I love how the heat radiates back on you immediately when you lay down!

You've tested *all* of them? You find the Nemo more comfortable than an Etherlite XT? An REI Helix? An Exped? A Rapide SL? That doesn't compute for me. The Nemo is more comfy than a Neoair but well below all of those.

You may have to keep trying. It took me a long time to find a sleeping pad that I was good with. I eventually now use a sea to summit ether light women's pad that's long and wide. It has the extra padding in the hips and shoulders for me as I'm an active side sleeper. That's when I'm on the ground though. I prefer hammocks now because I just can't stand sleeping on the ground with a pad unless I'm camping with my wife so then I find a way to make it work for a few days

I’m a 6’4” 220 lb late middle aged side sleeper with a bad back. I got a Sea to Summit Ether Light XT Extreme Cold-Weather Insulated Sleeping Pad, Rectangular last year and I love it. It’s 4” thick. I sleep very comfortably on it and my hip bone doesn’t touch the ground like what happens with most other pads.

I'm using sea to summit ultralight insulated pad since many years. Weight and volume are critical for me. Works better than an underquilt for me.

I have the summit ether light wide, started using when 300 lbs 5’5. It was the 4th pad I tried and the one I have kept using and would recommend. Haven’t tried the others though.

I am the same weight as you so maybe can help here. Have you looked at the Sea to Summit XR or XR Pro? The R values are 4.1 and 7.4 respectively, with the Pro being heavier too. The regular is ~22" and 19.8oz vs the BA at 18oz, so if you can fit on a <6' pad, that gives you another 2"/10% of width and almost doubles your R-value for only ~2oz. I side sleep and roll a lot on mine and find it very comfy. Note I do have a large though because I'm over 6' tall and don't like my feet to hang off the end, it is 25.2" wide (6'6" long) but sadly much heavier at 25.4oz

Sleeping bag won't do anything for comfort while laying down. A good pad is what you want. Sea to Summit Ether XT Light, followed by Nemo Tensor, are my recommendations. Pillows are more forgiving. Wife and I use the Therm-a-rest ones.

I also love my Etherlite rec. large. I have around 100 nights on it, and I sleep better than at home. But I am in the opposite boat now, trying to find something lighter. They are heavily discounted right now (for example at Bergfreunde, but that ships from the EU), so it might be worth picking one up to try.

Same! I loved the feel of that pad, but I thought mine was defective!

That's so funny, I had the opposite experience. Used an XLite for a good long while and just accepted that my arms and shoulders always felt sore in the morning and/or went numb overnight. Switched to a Ether Light XT Insulated (regular mummy, not wide), took a tiny weight penalty, slept like a baby ever since. Sleeping pads are as personal as underwear. I will seriously never understand why one person thinks their preferred pad will work for someone else. You just gotta try a few till you find the one that works for your (unique, individual) body.

The brand new (literally new this week) Sea to Summit Etherlight XR pad looks impressive for weight to R-value ratio. Might check that out. It replaced the XT which they spent the last few months selling 50% off (I got one). So it has the same quilted/tufted/dimple style baffling as the Tensor, sorta. There's a huge difference in comfort depending on your body between the dimpled baffling of the Etherlight/Tensor and the horizontal baffling of the Xlite. I can't sleep on horizontal baffling despite all the good features of the Xlite. I've been happy with the Etherlight, which I always purchase at REI and return within the year because they can develop pinholes especially around where your elbows contact the pad when rising or laying down. I didn't buy the last one from REI because it was so cheap direct from S2S but the next time I need a new one I'm going with the new XR.

yuuuuup I use Sea to Summit Etherlight pads and it's the same. Buy from REI and just return within the year. Buy new when a new upgrade comes out. Like they just upgraded it and called it the XR, less weight, better R-value. I just put up with the pinholes and patching them on trail because I can't sleep better on any other pad.

Most don't last very long if you're using them more than 30 nights a year in my experience. These manufacturers are banking on most buyers using them less than that. For super avid backpackers and thru-hikers, obviously we use them way more and therefore need to replace them more frequently. I've always bought them from REI and get them replaced under their policy within the year. Or if it's little seam weld pinholes, take advantage of the warranty (I use Sea 2 Summit pads mostly). But yeah I think the companies just absorb the loss from heavy users, who are a minority of total sales they make globally. Most people just buy a pad to go camping once or twice a year and it just sits in their closet for years before it gets the same amount of camp time as we'd put it through halfway into a thru-hike. Not sure if that made sense - still pre-caffeine today edit: getting holes from pokey things is a given despite the best careful babying if you're out enough, especially in the desert. but i'm not really talking about those kind of holes (that can be patched) - i mean the phantom leaks that can't be identified or fixed easily, like seam welds, valve stuff, etc. (especially on quilted/dimpled baffles) whenever i've returned a pad it's got several patches on it - i keep the solider well bandaged until he can't fight any more

All my sea to summit pads have developed stress pinholes in the dimple welds, nothing to do with anything I could have done or prevented as a user, it's a common defect with that style of baffle.

Good for you for taking care of all your gear. I also take good care of my gear and get many miles out of it. Your response sounds quite lecture-y and finger waggy tbh, making the assumption that others don't take good care of their gear. All my sea to summit pads have developed stress pinholes in the dimple welds, nothing to do with anything I could have done or prevented as a user, it's a common defect with that style of baffle. Manufacture defects on pads are quite common and have nothing to do with user care. No matter how much you baby your sleeping pad, if it has a weak valve attachment, it's gonna develop a leak.

they both kinda suck tbh try a nemo tensor, big agnes rapide, or sea to summit etherlite, or thermarest neo air

Hey I have the black  S2S Ether Light XT Air Sleeping Mat (reg-wide) I normally hammock camp but tried a tent. I'm a side sleeper and had one of the worst nights sleep on the S2S Ether, I had to swap with my partner who has a thin 1 inch think Thermarest. Something about the S2S made my spine bend the wrong way on my side.

Yes on the ether light but get the newer XR version which has a higher r rating.

Stronger seams is promising. I loved the comfort level of etherlight xt but had multiple get air leaks in all the seams so I gave up on using it.

i have a couple etherlights for different seasons. My partner got the REI helix which surprised me for how good it is for the price

I’d recommend looking at the Sea to Summit Etherlight XT insulated pads as they are currently on sale for 50% off direct from S2S. They generally are in the weight range of the pads you are looking at but right at the $100 price range right now. The R rating is only 3.2 so they won’t be as warm as some of your other options, but at the temps you mentioned it would be just fine.

I thought I needed a thick wide pad as a side sleeper. I got an S2S Etherlight. About half way thru a thru in ‘21 I had to try an XLite, because supply chain. Dropped about 9ozs and kicked myself the rest of the way down the trail for being so gullible. The XLite was much more comfortable for me sleeping and I could really feel those 9ozs off my back. Get that and bring a few ozs of Blue Chew and your gal will carry the rest of the gear! Ha!

The new **Sea to Summit Etherlite XR** Mummy Large. 10cm/4inches thick and comfy. Packs small. 580grams. other good current inflatable pads - Nemo Tensor All Season - Thermarest NeoAir NXT - Naturehike R5.8 (Budget option at $90)

They're selling off the S2S XT right now. Good deals to be had for the most comfortable sleeping pad there is.

Sea To Summit Etherlite XR

The Sea to Summit Etherlite Woman has been replaced by the new Etherlite **XR** which is warmer lighter and packs smaller. My advice would be to test lie in a shop - Thermarest NeoAir NXT - [Sea to Summit Etherlite XR](https://seatosummit.eu/en-ch/products/ether-light-xr-insulated-air-sleeping-pad) - [Nemo Tensor All Season](https://www.nemoequipment.com/products/tensor-all-season-insulated-sleeping-pad)

The newly updated version Etherlite X**R** which came out around April is a much better pad. Packs smaller, weighs less and is much warmer. It uses silver reflection film instead of insulation. I owned the XT before and let me tell you if you can sell the XT and buy the XR it's that good. https://seatosummit.com/products/ether-light-xr-insulated-air-sleeping-pad?srsltid=AfmBOoq_8pObfHzj71aOkuP45MvfnKwCO0wnHfKuJmTFyxk1hzqLM942 Ether Light XR Insulated Air Sleeping Pad

OT, the North American clearance price on the remaining XT mats is incredible. $59 for the women's XT.

They’re half off right now, about $100

I love the etherlight, I’m a side sleeper and it really helps prevent my arm from falling asleep. The only downside is the bulk. It takes up a lot of space in my pack. When I’m out for long hauls I don’t have the room for it and switch to the Tensor All-Season.

Same. Had the chance to try both in stores. I am a side sleeper / stomach who turn around a fair bit and just preferred the Ether (Long Wide)

I went with the S2S ether light XT wide. I think it is 4" / 10 cm thick whereas my previous thermarest prolite was 5cm... My hip needs 10cm. At the minimum.

I went with the S2S Ether Light XR for side sleeping comfort, good weight and size, and upgraded r-value. No regrets!

I've seen a few comments about cutting a Thinlight pad down to size, if required. But from the specs the Thinlight is shorter and narrower than typical inflatable pads. I've just ordered a regular size S2S Ether Light XR, which is 72in long x 21.7in wide. The rolled Thinlight pad is 58.7in long x 19in wide. Is this an issue? I also want to use a Thinlight pad to protect my inflatable pad.

This is why I've switched to Kilos elite pads after wasting decades and £££s on Nemo, Thermarest, etc. Kilos pads are at least 1/2 the price of the 'premium', but still unreliable, pads and easily the comfiest I've ever used. They look similar to the S2S Ether lites (which started leaking after 3 nights) but are way comfier for some reason.

This one from S2S might fit the bill: [https://seatosummit.com/products/ether-light-xr-pro-insulated-air-sleeping-pad?variant=44032184778925](https://seatosummit.com/products/ether-light-xr-pro-insulated-air-sleeping-pad?variant=44032184778925) I've had no issues with my UL Insulated one, though its R is \~ 3 so I combine it with a 2.5cm CCF pad for winter.

Buy once cry once. Thermarest, Nemo, Sea to Summit. They make the best small, lightweight, comfortable pads.

I was in the same dilemma this week and ended up with the ether lite XR (XR is the new version). I think it’s incredibly comfortable from my one night this week. If you want something potentially comfier, look at the thermarest Neoloft, it’s more like a puffy air mattress if you’re into that. If you don’t care about size weight, look into something self inflating or something like a exped mega mat

I had the old model and it made horrible noise in tent and especially when sleeping in cabins. My camping mates hated me. The spund was more like a rubbery groan instead of crinkly chip bag sound, very annoying. Hope that has been fixed.

It's literally not possible. The megamats are comfortable because they have several inches of foam inside of them. The foam makes the pad super soft and supportive. There is no way to make that packable. Backpacking air pads are either air with insulation or foam filled but really thin, like 1.5 inches. The most comfortable backpacking pad I've found is the sea to summit light because it has a lot of small baffles instead of long continuous tubes like most pads. That makes it a lot more supportive. But it will never compare to a megamat.

Nemo Tensor, Kilos Gear AeroCloud Elite, Big Agnes Rapide SL, Thermarest NeoLoft. The Sea To Summit Etherlight XT is also comfortable but heavy and bulky for a backpacking pad.

Trie the STS XT at REO and compared to other pads it is loud when moving around. In addition it is bulky when packed and has a lower R value. I also have the Thermorest a=x lite and prefer the Nemo All Season.

Tra i menzionati possiedo il Sea to Summit e posso parlarne bene. A pari caratteristiche c'è il cinese Naturhike di cui ne parlano molto bene.

Excellent mattress! I used it with pleasure but then switched to the thermarest which is lighter and I feel great with it.

Ive had the same issue with the NXT. I went with S2S, its great for me and my tosses and turns.

Ive the new one. Its slipper as most of these pads. Ive put some silicon on it so I dont have that problem.

S2S XR. It's great.

Sea to summit etherlite xt has been my go to. Best nights sleep I've had as a side sleeper

My wife has S2S mattress - the one you are looking at or slightly colder and she likes to sleep warm. We were doing Tour du Mt Blanc this year and you want all the comfort you can get for multiple days of 1000 m up and downs even if it is worth few grams more. Nemo seems to be thicker though? And you don't have to inflate it all the way, so it will make more room for your hips but watch out, too close to the ground and it'll get cold in the middle of the night. We both use Cumulus 250 quilts and I have Thermarest NeoAir Xlite (R 4.5) - I was sweating some nights so if anything, Nemo will be too warm for the proper Summer and maybe shoulder months.

I really like the ether light!

I switched from a s2s eatherlight xt to a zenbivy ultralight and have quite enjoyed it.

I was sporting the s2s ether light and had to let so much air out. Got zenbivy ultralight fully inflated is wonderful. 200 pounds side to stomach sleeper. Seems to have a different type stretchy material.

I went from an OK REI inflatable to a NEMO tensor and then a Sea to Summit Etherlite XT. The waffle-looking baffles on the two latter pads were a huge improvement in comfort. I think the Etherlite is slightly more comfortable but I switched mostly for durability reasons. 3+ inch thick pad with the waffle pattern is the way to go in my book. Back feels better in the morning and I wake up way less often because some body part fell asleep.

Sea to Summit Etherlite XR. 4" thick, 4.1 R value. Super comfy and no drama in getting it inflated.

I’m 6’ 180 lbs, typically a side sleeper. My favorite pad is the Sea to Summit Women’s Ether Light XT. 6’ by 25 inches and 4 inches thick… great for side sleeping. Yup, I sleep on a womens pad - the men’s large/wide pads are unnecessarily long for me as a side sleeper. Why carry weight I don’t use?

oh hello, followed the same route as you. Just picked up an S2S Ether Light today to test, as I'm a cold side sleeper and haven't quite found the solution yet. How have you found it for warmth? It is heavier, but sleep deprivation weights a lot as well.

Sea to Summit has a structure they call "air sprung cell". I personally own an old NeoAir but have tested a Sea to summit pad with that structure and I must say, it was much comfier. I've been trying to justify chucking in the money for a new pad, but am not there yet.

Check out the sleeping pad comparison chart I posted. It's a quick reference for pack size and weight across multiple brands. The best 2 light air pads that are still comfortable: Big Agnes Rapide SL NEMO Tensor (any version really) I personally prefer the Rapide SL but my wife really likes the Tensor. Both available in 20x72 up to 25x78, I always recommend at least a 25" wide. Both insulated and smaller packing that the other that may offer more comfort or insulation like the Big Agnes Campmeister Deluxe or Therm-a-Rest NeoLoft. Maybe not as small as some cheaper Amazon pads or the infamous Klymit static V but guaranteed more comfortable. They also have lifetime warranty which I know doesn't help you in the woods, but does protect your investment in the event there's a leak you can't find. The Big Agnes zoom is too crinkly like all the Thermarest air pads are. The Sea to summit etherlight packs too big for what it is and the external material is super squeaky on a tent floor.

I can’t say for these specific models but I have owned three sleeping pads in my 41 years, Sea to summit, Nemo, and thermarest. The only one that has never gotten a hole in it is the thermarest and it is my oldest pad!

When I was in the boy scouts, they taught us how to make a bed by cutting/scavenging pine branches. That was the most comfortable camping bed I've ever slept on. Literally better than the big ass cot my Dad used to make us lug around. I don't do it all the time as I don't want to just be cutting branches off trees because I feel like that's not cool. But the last I went camping there was a big storm that had came through this valley and I found so many small pine branches. That was the 3rd time I made a nature cot or whatever you would call that. Omfg, that shit was more comfortable than my bed at home. Those little pine needles gently poking my back, holy shit I slept like a log, no pun intended. 🤭 But as for a an actual answer to your question, mine will be like half assed. I got this air filled one from the return rack in REI, I think its made by Sea to Summit. It's been my favorite for longer hike to camp trips. It rolls up relatively small, no pillow built-in, but it really gets the job done when I need something that fits in my pack. It's in my storage unit so I can't just grab it to tell you the name of it. I googled it tho, and I believe it's the Ether Light XT. And then I just use an inflatable pillow with it. My favorite has always been the foam/air with built-in pillow ones that you were talking about, but I feel you, that thingy is so bulky! Stay safe, and have a fun trip homie! 🙏🤘

Don’t go self inflating if you want that much height. Car camping, yes, any of the massive, tough, heavy self inflating mats will be fine.   Go to a camping/bushwalking shop and try a Nemo tensor insulated (wide). Fill it up then let out juuuust a bit of air. You can put a closed cell foam mat underneath if you can’t get a balance between a comfortable shape and your hips touching the ground.  Sea to summit are also comfortable but don’t insulate as well.   Also - I know you know this - it’s easier if you can lose a bit of weight. I find it much less comfortable sleeping on the ground after gaining weight. 

I don't like the horizontal baffles and height. I tend to fall off an xlite. That's why I got that sea to summit ultralight insulated one - much more stable and despite being thinner it's warm and comfortable on my hips.  But some people don't have that issue with xlites.  I'm selling my old xlite on gear trade subreddit. I'm sure it makes no sense for someone in the EU to buy from me in NA. But I'd it does then take a look at my profile and see if the price makes sense for you. 

Yes. Camped in around -7 deg C in the snow with it as a longer trip shakedown.  No issues with cold due to the pad  Also on the PCT we started in late March so we had cold nights (close to -5 C) in the desert including adjacent to snow around San Jacinto.  I replaced it with CCF in the Sierras but we timed that to have almost no snow. Only a couple cold nights in the Sierras. I like the S2S pad and it's likely to become my go to for an inflatable pad (thus I am selling those xlites, but keeping my double exped 3R)

Canadian side sleeper here. I often 3 season camp down past -5 deg ( probably closer to -10 deg ) depending on what the mountains decide to do. Not much camping in snow but a lot of waking up in it. I've never needed R value of 5. Are you sure you do? Have you tried anything else? Exped lists their 5R being good to -20 C. That's not 3 season is it? That seems overkill to me. Exped 3R in the shortest length (with any dangling feet on top of a pack or something) would be my preference for an inflatable for the brand's you listed. It's quite a bit lighter than those options and is worth a consideration. I have slept many nights in the previous version of it in a double wide with a partner (which may have had a slightly different R value than what is available now).  I also just spent a lot of nights on a slow LASH on the PCT (where I had slept in the temperatures of interest  - down below -5 C in both desert and mountains) on a sea to summit ultralight insulated short pad. This was very comfortable and warm. it's like 350 grams. Eventually on trail I went with a CCF pad (Nemo Switchback ) to reduce base weight a bit - and that hurt my hips when camping on some surfaces but was a compromise I accepted for many nights. This was much lower R value but warm enough on cold nights down below -5 C.  

sea to summit ether light xt - sweet spot for weight and durability. I prefer my exped lw for comfort (it's wide and even more silent) but these are not as durable. 3-4r are enough for what I do, for iceland I'd personally take a warmer one. But I'm a quilt user.

Ether light I found noisy and sold it.

I recently swapped to the Sea to Summit Ether Light XT Insulated and can definitely recommend it. I’m a side sleeper and the extra thickness is welcome but it’s not much bulkier packed than my previous pad.

Thanks - I’m fairly certain that’s the one I’ve got.

Sea to Summit EtherLight XT Insulated. I also have a NEMO Tensor Ultralight but find it too thin for side-sleeping.

Samw with my sea to summit absolutely unbelievable how comfy it is.

I own and use both. Both are now backups to my therm a rest neo loft bc that big boy is like sleeping in a real bed and is worth every ounce. But between the Nemo and ether light I’d say the Nemo is lighter and comfy, but the ether light is a tiny bit thicker and more comfortable, and the ether light is also more durable. My Nemo is still functional but I did have to patch it up once.

Looking to upgrade my sleeping pad in a 12L 3-season overnighter kit, so optimizing for packed size. I know about therm-a-rest 3/4 pads, but I've had issues with nerve compression due to the baffle design, making it really hard to sleep. If there's nothing better out there, I can try to make it work. Its specs are hard to beat... I've been eyeballing the new S2S XR pad. Seems to pack even smaller than their shortest UltraLite pad (the orange one.) Weirdly the small and regular have the same packed size listed on the S2S site. Heavier than the x-lite but pretty packable, comparable r-value and I could actually sleep on it. Any other pads people would recommend? Really aiming for >3 R-value minimum so I can get 3 season usage. Thanks Edit: Ordered the Tensor Elite Short to couple with a torso-length GG thinlight. Technically that's two pads and not one, but being able to just throw the thinlight on the outside of the pack makes that a non-issue, plus I get the various uses it provides. We'll see if I regret my decision...

this is probably what I'm going to end up going with. ordered the tensor elite short and an S2S XR short to compare. S2S is heavier and bulkier but still pretty small with a better r value and durability. although at 12L it probably won't win out over the tensor

You need a warmer sleeping pad. Or double up the S2S.

Went from Tensor to a S2S Etherlight and it is even better. The extra 1/2” of thickness makes a lot of difference if you’re a side sleeper (or heavier)

That’s what I did also. Went from crappy Amazon pad, to x-lite, to Tensor, to Etherlight. Each one was leaps and bounds improvement over the previous.

etherlight xt pads never had down. they were synthetic insulated

For another option... I had a sea to summit etherlite xt for 5 years and loved it. Eventually died. Tried saving weight and got a neoair xlite nxt. Hated it and it broke within a month. Crinkly and uncomfortable. Went back to the sea to summit and it's good.

I highly rate the nemo tensor (3.5"). I used to use a sea to summit etherlite xt (4") which was really comfy but heavy and had 3 of them with plastic weld multi-failure. I've tried thermarest neoair xlight nxt (3") and i hated it, felt like sleeping on a puffy bag of chips and unstable. For the pain you're feeling though, most mats are similar and the decider is getting a mat thick enough that you can deflate it so soften the pressure. Deflating the mat a bit if i'm going to sleep on the back helps with back pain and general pressure by increasing contact area. Raising the feet also helps, usually i put spare clothes under the feet. Choosing a sufficiently large/wide mat too.

I have the Sea to Summit Ultralight Insulated pad and I find it quite comfortable. I’m a side sleeper and it feels comparable to a normal bed at home. I’ve been using it for 7 years now and it’s still in perfect shape. Never had a puncture or any kind of issue with it. I find it significantly more comfortable than the cheap pad I had before it

Side sleeper here. +1 for the Ether lite. On sale right now for $100

Side sleeper with a bad back here. Can highly recommend the sea 2 summit ether light xt large rectangular. Certain exped pads with vertical baffles sound promising also but I've not tried them

Side sleeper here. I have the ether light xt large wide. It's quite good for me. Id like to try out an exped mat with vertical baffles though

Love my Sea to Summit Ether Lite XT. Recently went back to tent after hammocking for years and pad was biggest issue I had before with sleeping in tents. I found the Ether Lite a great pad (light, comfortable and pretty affordable relative to others)

Ether light is comfortable but if I was to purchase one now I’d probably go for thermarest neoloft based on reviews I’ve seen. Just above £200 but look out for offers

I also tried them both (NeoAir XLite NXT and now the Ether light XR) and can confirm the Sea to Summit is so much more comfortable and also more grippy. The therm a rest felt like a balloon and although it did feel warmer, the comfort wasn't even close

Maybe another option. The Sea to Summit Ether light XR is great to me. Thick enough, light enough and quite a non slippery surface with no noise. I heard the NeoLoft can be kinda unstable and balloony. Not experienced with the Zenbivy myself

Yup, if it's as comfortable as the previous model and delivers on the 4.1 R-value, it would be the dream pad for me. The current XT insulated is at best a 2.5 not a 3.2.

They might have fixed that already with the XT. At least the XT insulated I bought last year is silent, not a even a hint of crinkling.

Also a side sleeper. +1 on the Ether Light mentioned by another commenter. For pillow, I have a stuff sack that has a layer of fleece on the inside- holds my sleeping clothes by day, at night I turn it inside out and shove my puffy inside. I find that more comfortable than a blow up pillow.

Ether light xt (sea to summit) is 4in thick and good for side sleepers. I use it for backpacking, so it should meet your size requirements.

I actually don’t have a problem with it (well not just me but my backpacking buddies)- put hiking clothes under it and it cuts down- there’s far worse

In November I went to a store and blew one up new and laid on it on the showroom floor. It was comfortable but sounded like a loud squeaky balloon. Every time I shifted weight or switched sides it was loud. Even someone walking by looked at me and said “that’s really noisy”. Because of this I bought the Nemo Tensor which is much quieter than the Sea to Summit.

I mis-read the post. I didn’t know there is an XR model coming out. I tried the XT

I’ve slept well — like *well* — in the backcountry for the first time this summer thanks to the StS Etherlight XR mummy. (No experience with the prior etherlight, which I think some might be commenting on.) It’s absolutely worth the few extra oz to me, and the packed size is still fairly small. I previously was using the NeoAir, and it’s just no contest. I don’t slide off the StS, and I can sleep on my side. I will start to feel the pressure on my hip and have to change position occasionally, but probably don’t end up doing that much more than when I’m at home. I’d thought about buying the wide version because my arms always slid off and were uncomfortable with the NeoAir. I went with the regular width mummy StS and have had no problems with any body parts sliding off. :) Thought about the Nemo Tensor(s) real hard the last few years but never purchased one due to the reported leakage potential even with occasional use. I haven’t tried the BA. I tried the regular (non-mummy) exped 5R last summer car camping. It has raised side baffles (similar approach to BA), and I found it more comfortable than the neoair. So I bought the exped 5R mummy this summer for backpacking. 1. It’s a very aggressive taper on the mummy. (Whereas the ether XR is relaxed.) 2. Its packed size was significantly larger than the neoair, and I couldn’t actually fit it into my pack in the spot that works best. Luckily I then saw that the Ether was a new version and returned the exped mummy, got the StS. The StS is more comfortable than the 5R rectangle, and I’ll probably use it for car camping too in the future.

The XR has not been very slippery in my experience. I stay in place better on it compared to other pads I've had, and it stays in place better on the tent floor. I think if you want a wide pad because there's literally not enough room for your arms, etc., on the regular width, or that sort of thing, a wide absolutely makes sense. But if you want a wide pad because your arms (or you) technically fit on the pad but tend to slip off, it may be worth seeing how you do with a less slippery pad.

I’ve always slept terribly on NeoAirs for the reasons you described. It made such a huge difference to change to the Sea to Summit etherlight XR.

Same. I think the few extra ounces for the XR is worth finally getting a decent’s night sleep while backpacking.

I think you may have accidentally pulled the 18 oz figure from the Nemo Extreme, or the 2nd smallest size of the BA Rapide SL. If comparing pads of the same length/shape/R-value, multiple options mentioned in this thread are closer than 6 oz to the XLite. NeoAir Xlite NXT. S, Regular (66", 72"): 11.5 oz, 13 oz. R = 4.1. NeoAir Xlite NXT XTherm. Regular (72"; this is the smallest)): 15.5 oz. R = 7.3. Nemo Tensor All Season. Reg mummy (72"; this is the smallest): 14.1 oz. R = 5.4. Nemo Extreme Conditions. Reg mummy, Regular (72"; this is the shortest): 17 oz, 18 oz. R = 8.5. Big Agnes Rapide SL. Petite, Reg (66", 72"): 17 oz, 18 oz. R = 4.8. Big Agnes Zoom SL. Regular (72"; this is smallest): 14 oz. R = 4.1. Sea to Summit Etherlight XR. S, M mummy (\*66", \*72"): 15.7 oz, 17.6 oz. R = 4.1. \*These are 21.7" and 21.3" wide respectively (compared to 20" for all of the others).

I wrote in another comment -- the Sea to Summit Etherlight XR is a little bit wider than others in the small, regular sizes (21.7" wide for small mummy, 21.2" for regular mummy). I don't know that this would make a difference for people with broader shoulders, but I have a fairly slight frame and it did make a difference for me in that my arms don't tend to slip off as easily. (Although being more grippy is probably also a factor).

See a recent thread for some more feedback on this pad. I love the StS XR. Absolutely worth the weight over my NeoAir XLite. I sleep so much better. (Side, back, stomach). The baffles are comfortable and I don’t slide around on the pad. I can’t speak to durability or sub freezing temps.

100% this - your Ether Light only has an R-value of 3.2 which is way too low for 0-15°F temps (you need at least 5+ for those conditions), no amount of merino will fix heat loss through the ground.

I’ve slept on the Comfort Plus for a couple dozen nights and just picked up the Ether Light XT Extreme after having a couple nights of bad hip pain using the comfort plus. I haven’t slept on the Ether Light yet, but it seems to be much more comfortable for side sleepers like myself. I got the regular sized Ether Light XT Extreme and have the rectangular Comfort Plus. The Ether Light is a lot smaller when packed and I’m sure the non-extreme would be even smaller yet when packed. I also think the 3” thickness of the Comfort Plus is slightly exaggerated, seems to be less than that, but that’s anecdotal. The Ether Light is markedly thicker and fellow side sleepers seem to really enjoy it. I think both are pretty nice, but based on the necessity to sleep on your side and reduce packed size/weight, would recommend the Ether Light.

The Ether Light XT was very comfortable, would definitely recommend if you’re primarily a side sleeper. If not, and you will be primarily car camping, the Comfort Plus will do well. The Ether Light’s are not on sale anymore either which is a bit of a bummer.

It’s because that pad specifically is known to do that. The sea to summit ultralight insulated pads are fabricated completely differently and make zero noise when you move around. That’s not a reason to switch to foam because there are better solutions

I’ve never used that pad, I have the sea to summit ultralight insulated pad and it works very well. It’s comfortable and reliable and packs down really small. Any higher end pad (like in the $100+) range should be good

I mean, it’s not. That’s the full price. This is what a sale listing looks like on REI, the prices are in red & the percentage off is next to the price https://www.rei.com/product/250165/sea-to-summit-ether-light-xt-insulated-sleeping-pad

Well for whatever reason, it’s cheaper and worth spending a few more bucks for a high quality product

Let me guess — Zoom UL? I ended up going with the Sea to Summit Ether Light XR, actually. I found out my local store was having a big sale on S2S gear, so I snagged mine for €190. The AeroCloud UL would’ve cost me €127 after VAT and import fees. Saving €63 just wasn’t enough to give up the 2-year warranty and local support. I have to say, I’m pretty impressed with the new XR mat. It’s the first ultralight mat I’ve used that doesn’t sound like a bag of chips when I move around — no annoying crinkle from the heat-reflective foil. The outer fabric is also surprisingly quiet. Comfort-wise, it’s excellent. Sure, there are more luxurious mats out there, like the Exped Megamat Ultra, but those are way heavier and bulkier. If the R-value holds up in real-world conditions, I’ll be even happier. My only real gripe so far is the thickness as it is advertised as 10 cm thick, while the reality is 9,5 cm ([https://imgur.com/a/Fgd9pHt](https://imgur.com/a/Fgd9pHt))

Sea To Summit Ether Light XR (XT is the old model, definitely go for the XR it's lighter, warmer and pack smaller) is a great all-rounder, one of the best actually when it comes to comfort-weigh-pack size ratio. Other good all-rounders are REI Helix and Zenbivy Ultralight Mattress, both of these has very similar comfort but are slightly heavier. If you seek ultimate comfort there would be there competitors: Zenbivy Flex Air Mattress, ThermaRest NeoLoft and Exped MegaMat Ultra. Each of these are basically best of the class, which one would be the best comes down to personal preferences as each of them using different baffle construction.

I love my sea to summit ether lite. Im also a big dude who sleeps on his side. I have the biggest one and the insulated version. Its more than $200 but goes on sale occasionally and its well worth it

Just switched from the NXT to the Sea to Summit XR. It’s a bit heavier but more comfortable, like night and day for me. Decent R Value, packs small, quieter. Pads are definitely an individual choice, so I use the REI return policy to make changes.

I had the opposite experience somehow. I had to return the etherlite after waking up with a sore back every night.

One of the guys I go on trips with got his this week. Be interesting to see how it performs vs my S2S ether extreme!

Ether light xr has been the most comfortable pad I've had. Highly recommend. Easily the best upgrade to my sleep when backpacking. It also has a blow bag pump to blow up the pad that's part of the bag it comes in. Don't make my mistake and hold it against your mouth to gill it. All you do is connect it, hold it open and blow a few times and the whole thing fills with air damn near instantly, then fill the pad. Took me like 20 seconds to blow up my pad (not that it really takes that long without it.

Surface it's not smooth rubber but reminds me of a fabric almost? I definitely didn't slide around on it much but I don't think that feature is a deal maker. Size wise I'm a bigger guy and I went with the regular tapered one, my arms do just kinda drop off the sides so if you're in a similar boat consider the rectangular one for more room. Pack size is about the size of a 32 oz nalgene water bottle and actually a bit smaller. So quite compact. The tapered pad works for me size wise but it'd definitely be more comfortable it I had gone with the rectangular version. And yes the bag uses pretty much an air vortex, not be to be a huge dork but its using a phenomenon called the Bernoulli principal.

Can't say long term but I just replace my sea to summit pad with a Tensor All season. Very comfy just about to leave on tour with it.

I really like the Sea to Summit Etherlite. I use it for bikepacking, backpacking, music festivals...pretty much everything. I need an alarm to get up in the morning. 4 inches thick. Quiet. Mine weighed in at 20.8 oz. If you aren't super tall. I reccomend the women's version. You can get a 25"x72" "women's" pad and it is a little bit warmer in R value than the men's version. But no matter what you get for length...the 25" wide version is worth it for sure.

is that the new one that just came out? they say its a bit warmer but packs down smaller than the old one. they were selling off the old model cheap on the company website a few weeks ago. I don't know if they have any left but I got the women's wide for $60. Its my backup now! 🤣

Agreed the Exped is surprisingly comfy for a side sleeper. I went with the ultra 5r but that shouldn’t make a difference. Tried and eventually got rid of: thermarest, ether light, klymit.

I have the Tensor and Ether Light XT. I find the latter more comfortable. There's a significant difference in packed size between the two, but iiuc the XR is significantly smaller than the XT.

Agreed, I had to return my Etherlight XT since it was too cold to use even in summer. If these live up to their R-values this time it could be new king of comfort.

It's best if you can visit a local outdoor retailer like REI to try out some pads. That way you know what's comfortable for you, and can make some choices on picking the lightest pad that meets those needs. For me I find the Nemo Tensor (lightest), S2S Etherlight XR, and REI Helix (heaviest) to be reasonably comfortable pads as well. Xlite/Xtherm were definitely less comfortable last I tried.

Can't speak to the tensor, but just got the Either Light XR and it's really comfortable. I've been carrying around an absurdly large pad because I can never get comfortable as a side sleeper on most standard ones, and this is the best nights sleep I've gotten since switching. It probably comes down to the baffle style tbh. I've tried the vertical and horizontal ones and neither felt good on my shoulders or hips the next morning. If you don't like the dimple style baffles though, you should go with the tensor. Haven't pushed the temperature rating to it's limit yet, but if you're not going in extremely low temps I can't imagine 4.1 won't be enough for a majority of the year.

Im about 190. The pad sinks to the floor if I'm not fully laying down on it, but once I'm spread out it completely supports me with ample loft. Before this I've been carrying around a megamat lite 12, which is enormous but like sleeping in a bed. This is the first alternative pad that I've actually felt support in my shoulders and hips.

this pad is so comfy imo, my partner has it, i’ve borrowed it a few times and idk what i was thinking buying anything different. my partner is 6’2 200 lbs and a side sleeper, he really likes it. i bought the sea to summit ether light xr last year and im regretting it because i know what im missing out on (it’s the mec vectair)

As a cold sleeper for the love of God do not get the ether light. I had it for a while and I was just dang cold all the time unless it was properly warm out. The winter version is absurdly bulky. Even worse is I can't sleep on fully inflated pads so had to let some air out which reduces the r value even further. Then it developed a slow leak. I bought the nemo all season in wide and it's night and day on warmth and noise. Tbh though if dealing with freezing temps I'd be taking a winter mat as a cold sleeper. Or be prepared to bump with a foam supplemental mat. After some absolutely freezing nights I don't push boundaries on this. ETA thermarest wasn't thick enough for me but this was the old model the newer one is 0.5 thicker so maybe it's enough.

I just picked up a Sea to Summit sleeping pad earlier this summer after years of making do with the cheap Walmart foam pad. I've slept so much better with my new setup, especially because I also bought their inflatable pillow that attaches to the sleeping pad. Wasn't the cheapest setup but very well worth it.

Agree, I had one and it was very squeaky, sometimes even like rubbing balloons together. Could also be due to pad rubbing against tent floor. Exped pads never have the same issue.

I picked up the Ether Light XT extreme for £150 other month. R value is 6.2 and comfy

I have the SeatoSummit Ether Light XR Reg Wide and love it. Super comfortable, warm and quiet.

Basically the best value pad you can get right now. I have a S2S Etherlight, which is a great pad, but I'm looking to cut down the weight and pack size.

I have the XR version and it's not loud at all.

Looks like they're being discontinued? Maybe a new model is coming?

I got you, also a side sleeper, this is what I finally settled on: * [Ether Light XT Insulated Air Sleeping Pad - Regular Wide](https://seatosummit.com/products/ether-light-xt-insulated-sleeping-pad?variant=19512263278695) - 4" thick & 25" wide - After spending most of the AT on a 2" thick & 20" wide Neoair, the thickness and extra 5" of width of this pad is heaven when side sleeping. * [Nemo Fillo Camping Pillow](https://www.nemoequipment.com/products/fillo-backpacking-and-camping-pillow) - Hybrid foam and blow up pillow, best pillow I have tried, much better than the blow up only pillows. I usually only blow this up like 50% and it cradles my head real well. I also throw some clothes in a stuff sack and throw that between my knees when sleeping.

First thing is to experiment, try some ideas and figure out what combination of tricks work work best. Don't worry about having the lightest kit until you figure out what you want to do, then you can figure out how to trim weight. Here's a few cheap ideas that should work in some combination: I'm looking at your ether light and thinking that's probably too cold to be used alone, I'd start with layering a foam pad on top, ⅛in foam should do it or just try whatever is cheap. Putting the foam inside the sleeping bag can be a big warmth boost. Experiment with a VBL, you can try a Christmas tree bag for a few bucks, but beware of overheating and sweating too much. Get a lightweight blanket and trim/hem it to make a simple overquilt. Try an extra fleece sleep layer from amazon or something cheap. Bring a heat safe bottle and pour hot water in and sleep with that. Wear a beanie or pehaps a balaclava that you can roll down over your nose to your lips just enough to help pre warm the air before inhale but not too much to restrict breathing. It's tough to find a beanie that fits just right where it is bothe comfortable and functional but the right one can be very helpful at keeping warm. Try a mix of these, you probably have some of these already, see what works and what doesn't, then iterate until it's working for you.

I actually cross-shopped these three pads earlier this summer, and tried each one of them. My thoughts below: Packed size (smallest to largest): \-Nemo \-S2S \-Big Agnes Actual measured weight (lightest to heaviest): \-Nemo \-S2S \-Big Agnes Comfort (most comfy to least comfy): \-S2S \-Big Agnes \-Nemo I settled pretty happily on the S2S. It's significantly more comfy (IMO) than the other two. The other two have a slippery surface that makes the last 1" on each side unusable since you slide off it anyway. Even the Big Agnes, with it's raised outer baffle, doesn't help as much as you'd think since it's so slippery. For reference, I'm a side sleeper and move around quite a bit throughout the night. The S2S surface has more friction, is quieter, and just isolates movement overall a little bit better than the other two. I couldn't compare/contrast actual warmth since I've only taken them summer camping.

LOL, yeah I dove pretty hard into upgrading my sleep system this year. I tried the rectangular reg/wide in all pads. I settled on the S2S and love it. I used the Nemo several nights as well as the S2S several nights. The S2S is way ahead of the Nemo in terms of comfort, with only a slight penalty in weight. Packability is pretty similar, with a slight nod to the Nemo. You may be thinking of the previous gen S2S "XT" pads, which were not very packable, slightly heavier, colder, and maybe louder? The new "XR" version is fantastic. Big Agnes was another step up in bulk and weight, and I just couldn't justify either when the comfort wasn't as great as the S2S (which surprised me). I never camped with the Big Agnes, only tried it at home.

That comment is incorrect. It may be referring to a previous generation. Of the 3, the STS XR pad is least slippery. I sleep in pajamas and bring a leg up when I sleep, so the slipperiness is annoying for me since it just allows my leg to slide back down/off the pad (this is why I tried and ultimately moved away from the Nemo). The S2S had enough friction that it wasn’t an issue. I’m sure the dimples help, but the material itself is just different/better. Speaking of, I know the Nemo looks like it has dimples, but it really doesn’t. They do nothing.

I have it and love it. I’ve used basically all the popular pads over the years and I really, really enjoy the XR. It’s my current go-to.

Only used it about 7 or 8 nights, but none so far

31° is lowest I’ve had it out. Didn’t feel cold.

have you tried NEMO Tensors? Trail, Trail Ultralight, or Extreme Conditions - all pack down to 10x4in, 1lb 1oz to 1lb 4oz. 3.5in thick so very comfy for me as a restless side sleeper with hip problems! smaller/lighter than the sea to summit Ether Light XT Extreme i was using.

I have the S2S and love it! Side/back sleeper.

I've been liking the new Sea to Summit Ether Light XR Insulated. Usually go for a wide, but using the regular mummy and have gotten some good nights sleep on it. It is a bit loud though.

When you put it on a hardwood or vinyl floor, does it sound like a balloon rubbing when you move on it? The XT was bearable on silnylon tent bottom, but with wood hut or a PU tent bottom everyone in a 50 foot range hears every move.

I’ve only used mine twice (xt women’s insulated) and it was super comfortable but I tend to flop around a lot and my husband could hardly sleep with how noisy it was. It annoyed it me too. Super super comfortable though!

I have the sea to summit ether light insulated, they have the rectangle shape that is pretty wide and is currently on clearance. Lifetime warranty. I use it with the nemo disco, love the spoon shape. Might be worth a look at the s2s site, might still have some available

Ok, so for me foam makes a world of difference in comfort. Air pads feel more bouncy and I find it harder to roll over, etc, which is honestly hard enough later in pregnancy. I also found the Ether somewhat plastic feeling and crinkly sounding. The stretchy fabric on the Comfort Plus SI is super comfy and quiet. I have found the 3” enough, but I’m a back sleeper. I’ve had both the women’s version and the men’s and the women’s seemed to have denser foam, therefore a bit heavier for its size and warmer. Hope you find the perfect one for you!

Self-inflating mats are basically 1990’s technology. Heavy and less comfortable than fully inflatable mats. Get yourselves decent comfortable inflatable mats like. Sea to Summit Etherlight XT insulated or Exped Ultra.

Etherlight XR is the same excellent comfort as the XT with a better R value.

A fully inflatable mat like the Etherlight is lighter and much thicker. But significantly more money. Which is why I said what I said originally. 38 mm isn’t comfortable for most side sleepers.

Some mats have internal noise when you move: the crisp packet effect. Etherlights it’s the surface. It’s a much more rubber-like surface that produces a squeaking noise when you rub your skin over it. Doesn’t bother me, but it’s a different noise effect than other brands.

For me, only the S2S Ether Lt XT and the Nemo Tensor work. Horizontal baffles are a nightmare with the "slipping off" feeling and movement! I sleep on my side and stomach and sometimes back, and those two work great.

For me the S2S works where others don’t work. I find horizontal baffles extremely uncomfortable … it feels as if anything closer to the edge falls down and doesn’t give any support. So for me the S2S works for longer trips and for shorter I use a short version of the Nemo Tensor.

Agree. I have Nemo tensor and S2S Ether Lt xt because I find horizontal baffles very uncomfortable.

When I do use an inflatable, my S2S Ether XT is my favourite (best baffles and system with pillow etc).

Awesome! That's good to hear they sorted out the insulation problems of the XT. I just purchased the XR myself, but I haven't had the opportunity to use it anywhere other than my living room. It's definitely much comfier than my old thermarest !

https://imgur.com/a/78A23hn Hey all! Just picked up the new Etherlight XR, literally just opened and inflated it but curious if anyone has any questions for me about it compared to the old one. I don’t see any information about this online from YouTubers or any posts on Reddit. So let me know if you want me to check anything. The seams claimed to be improved, as far as I can tell they look a bit different than the last model (which I didn’t own) Inflating it with the two in one bag/inflated was pretty easy too! I live in Florida but am a sucker for new gear (my 11 year old pad just kicked the bucket) so I hope this isn’t too warm for the summer months. Leak testing it right now and will see if there are any issues out of the box.

I’m not super sensitive to it, and did not own the last one. That being said i think it’s pretty quiet compared to lots of other pads I’ve heard. Let me see if I can get a sound recording for you

Per the marketing material. Stronger seams, lighter, and a much smaller pack size. Also the insulation is better/different. Looking inside you can see reflective sheets.

Yep I follow what you’re saying. I see 0 ways that is possible on this current design https://imgur.com/a/xuKrSc7

I’m actually camping with it Saturday. Set up in a tent it’s very quiet actually. Not much sound when adjusting position. But yeah super comfy. And even me at 270lbs I can sit in my side and not bottom out (inflated a lot though)

I got ether light xr, and I got WL (I’m 6.2ft male), on sale for like 80$ new. It fits, I like it. I decided to get one because I got my girlfriend one in WR and she enjoyed it, pump system is easy, compact and it is 3 inch thick

I had cheap sleeping pad, had klymit pad, thermarest scout and now ether light. It isn’t slippery for me nor any different from others. Especially because it is 2 of us in 2p tent so there isn’t any room to slide too. And since I got Nemo sleeping bag it has a pocket for my pillow within hood, so pillow is always attached and isn’t sliding away. If you’re 6.2ft or under - try to score ether xr in women large and you’ll be comfy on budget

I've been curious about this: I've used the Ether Light XT Extreme (r-value 6.2) year round here in the PNW, and honestly felt like it has slept warmer than the Tensor Extreme Conditions (r-value 8.5) in the snow here. Unless you are talking about the original Ether Light XT *Insulated* (r-value 3.2)?

I've personally found the Ether Light XT Extreme to be pretty quiet. Along with it being the comfort king, imo. Been my primary pad for the past four years. This updated XR Pro packing down so much smaller and weighing somewhat less is very intriguing!

Nope! I’ve used the Ether Light XT, Ether Light XT Insulated, and Ether Light XT Extreme: all three are very quiet. Honestly think a lot of people have mixed up sleeping pads, or have some other/older Sea to Summit pad, when they mention noise on the XT models.

I do like to sleep comfortably when backpacking, and have spent a lot of time trying to figure out what works best for me. I've tried many pads over the past decades, including these two, along with similar Exped sleeping pads like the Ultra, Versa, and Dura. I am primarily a side sleeper, so that informs some of my sleeping experience on these, and am 190cm and 95kg. Personally I was not able to sleep comfortably on the Exped MegaMat Lite, or its siblings (Dura/Versa/Ultra). A through-line in my testing of these is the vertical baffling: I regularly wake up and find my arm is numb. I think these might work better for me if I was primarily a back or chest sleeper; lots of people like them and recommend them. But in my adulthood I've probably maximum only got about two hours of sleep at a time on a design like these. I have only had to contact Exped for warranty once, and they ended up shipping me a new unit before I even had to send the old one back: top marks here in support. I just picked up the Therm-a-rest NeoLoft before the holidays and took it on two trips in Mt Hood National Forest. Maybe the most comfortable backpacking pad I've personally used recently, even if the large (long wide, 78x26) weighs 2lbs! When fully inflated it is 4.6" thick. One of the few pads I've slept more than six straight hours on, which is kind of how I prioritize pads. Not only comfortable, but has a soft-touch stretchy fabric which feels good against the skin (I tend to sleep with quilts rather than bags). The first night I did wake up to find my arm was numb, so curious if that was a one-off with a weird sleeping position... R-value is 4.7, so I haven't used it at all in the past 45 days because of the cold where I am. It looks like the REI exclusivity is now over in early 2025, and this can be picked up lots of different places. Honestly the thing I dislike the most is the valves; I just don't care for the old-style Therm-a-rest valves. Realizing your question was specifically about those two, I also wanted to recommend what I have found to be my most comfortable pads in recent years: 1. Sea to Summit Ether Light XT Extreme Insulated. This specific pad and its sibling, Ether Light XT Insulated, have been my primary pads the past four-ish years. They are 4" thick and the most comfortable pads I've used, probably tied with the NeoLoft. Never woken with my arm numb, and the only pad I've ever slept seven-plus hours straight-through. In the PNW I use the non-Extreme-variant in the warmer half of the year, and the Extreme-variant in the colder half. The stuff sack with the inflation aid built-in is the smartest I've seen. Extreme version has an r-value of 6.2, and the non-Extreme version r-value is 3.2. The Extreme has that spider-web looking Thermolite insulation, which in my mind is the most reliable winter/cold insulation; it doesn't crinkle and potentially fail like newer thin reflective films in other lighter pads (NEMO Tensor, Big Agnes Rapide, etc). On the flip side that makes the Extreme very heavy, more than 2lbs, and also packs down the biggest of any backpacking pad I've owned. 2. REI Helix. Been using this on-and-off for the past few seasons. One of the few pads that has me sleeping through the night. It is only 3" thick, but I have found the trick is to fully inflate: the dimples do a good jump of evening out my weight and not experiencing any arm numbness. The long wide is 1lb 13oz, and seems pretty sturdy compared to other REI-brand pads I've used in the past; no leaks yet... R-value of 4.9. I always wake up refreshed and feeling good on those mats, baring any environmental issues outside of the pad. I cannot recommend the NeoLoft in that way yet, but will continue to use and test it out in the near future with an additional foam pad underneath to make it safe for snow conditions (as the r-value stacks). And I don't think I will ever recommend an Exped pad for backpacking. Exped does make fantastic foam inflating car-camping pads though!

Love my S to S pad also. Rivals my Select Comfort bed at home. Bought a back up in case they go out of business.

The Rapide SL is really excellent. My partner and I have both been using them for quite a while now and I think it’s the comfiest pad out there. I’m also a side sleeper. I tend to agree it’s not quite as warm as it claims but I still use it during autumn and spring. However I do tend to sleep quite cold so that’s a factor to bear in mind with my opinion. I have the Sea to Summit Etherlite XT (my mid winter mat), which has a similar construction to the XR, and it’s also a very, very comfortable pad. The XR is the newer version of it and looks like an excellent pad and will be perfect for year round use. They are extremely lightweight for that kind of warmth. The Sea to Summit pads also come with little velcro stickers that keep your pillow in place, if your pillow is covered in fuzzy fabric (they’re made to lock Sea to Summit’s own pillows specifically but any fuzzy fabric pillow would work) which is a feature I really love. Broadly speaking, the pads with a “cushioned” build like the Rapide and the Etherlights, are the most comfortable for most sleepers, but they do weigh slightly more than horizontal or vertical baffle pads. For me, as an increasingly creaky 40 something, it’s worth the extra weight for a good night’s sleep.

You can’t go wrong with them. Another feature I love about the Sea to Summit is that their storage sack is also the pump sack. I’ve often forgotten to bring my Big Agnes pump sack when I’ve had my Rapide with, whereas that never happens with the S2S one. When they brought out the XR range a few months ago, I actually seriously considered getting one but just couldn’t really justify it when I already have the XT. They really are fantastic mats.

Imo yes. The Sea to Summit mats are incredibly comfortable with 4-6inches of foam. I have one that has a built in pillow that I use for my feet (helps blood flow at night after a shitty day with the infantry Joes) and bought a wider inflatable pillow for my head. Best part is both the mat and pillow deflate and fit inside the small front pockets of the ruck.
