"Coming from the Razer viper ultimate at around 74 grams to the X2 Crazylight at 35 is a surreal experience, the mouse is basically as light as a feather to pick up and move it almost seems like it's not even there. ... As a fingertip grip user the feel of using a mouse this light is bar none, it makes it so much easier to pick up and re adjust and just moving it around with your wrist in fine movements it feels much more accurate and controllable."
"After the third run of another 15 miles a few days ago, I was sold and grinning from ear-to-ear afterwards. It's light, fast and propulsive, responsive, stable, nimble, grippy, comfortable, and protective. It pretty much does it all in a very lightweight package."
"it weighs under 350g"

"super comfy. ... And even me at 270lbs I can sit in my side and not bottom out (inflated a lot though)"
"definitely has improved our sleep quality a lot while camping ... boyfriend has back issues so a bad sleep set up is not really an option"
"I just put up with the pinholes and patching them on trail because I can't sleep better on any other pad. ... 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'm a side sleeper and my arms and shoulders ache and/or fall asleep or go numb on the Xlite. For whatver reason I can only sleep on dimpled baffles (tensor, etherlight)"

"Just had my second camp out with it. 0 issues with warmth at 50F , unsurprisingly. Also at 60f I didn ’t sleep hot so that ’s nice too."
"I can take it down to like 25-30F very comfortably."
"20 degrees F comfortably from below. Quilt wasn't up to it"

"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."
"Set up in a tent it ’s very quiet actually. Not much sound when adjusting position. ... i think it ’s pretty quiet compared to lots of other pads I ’ve heard."
"I have the XR version and it's not loud at all."

"is a great all-rounder, one of the best actually when it comes to comfort-weigh-pack size ratio."
"Tiny volume for each."
"Seems to pack even smaller than their shortest UltraLite pad (the orange one.) ... pretty packable ... still pretty small"

"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”."
"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."
"my husband could hardly sleep with how noisy it was ... It annoyed it me too."

"which started leaking after 3 nights"
"had multiple get air leaks in all the seams so I gave up on using it."
"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."

"Was bulk and weight that chased me away from self inflators years ago. ... I find the selfinflating foam so comfortable, more so than than air mats, but it's 790 grams, very bulky and just 3.8r. Can't justify it."
"The only downside is the bulk. ... It takes up a lot of space in my pack. ... When I I’m out for long hauls I don’t have the room for it and switch to the Tensor All-Season."
"on 5+ nighter with a bear can, the bulk and weight would no longer be worth it for me."

"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."
"It's so cold with a quilt, It really feels like it's doing nothing, even in summer conditions."
"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."

"Dropped about 9ozs and kicked myself the rest of the way down the trail for being so gullible. ... I could really feel those 9ozs off my back."
"For pack-in or hiking its FAR too heavy."
"Heavy af though. ... In general as a 2.8kg backpacking tent it's considered very heavy though, especially if you're taking days of food and other gear."
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
r/CampingGear • Almost there! Narrowed down my sleeping pad search and it's between the Nemo Tensor All season and Sea to Summit Ether light XR. What would you pick? ->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
r/CampingGear • Almost there! Narrowed down my sleeping pad search and it's between the Nemo Tensor All season and Sea to Summit Ether light XR. What would you pick? ->If comfort is a priority, you’ll do no better than the new Sea To Summit Ether Light XR.
r/Ultralight • Sleeping Pad Advice ->Im a side sleeper. I have the XLite. Often feels like the baffles lack structure at the sides so in the mornings I'm fidgeting around feeling like im rolling off the mat. Not used a Tensor although I have heard it offers much better support for side sleepers. Also, the Xlite suffers from mould spots on what seems the outside. For comfort though, from all the mats ive laid on, sea to summit are the most comfortable
r/Ultralight • Tensor all season vs Xlite Nxt? ->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.
r/CampingGear • Almost there! Narrowed down my sleeping pad search and it's between the Nemo Tensor All season and Sea to Summit Ether light XR. What would you pick? ->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.
r/CampingGear • Almost there! Narrowed down my sleeping pad search and it's between the Nemo Tensor All season and Sea to Summit Ether light XR. What would you pick? ->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.
r/CampingGear • Almost there! Narrowed down my sleeping pad search and it's between the Nemo Tensor All season and Sea to Summit Ether light XR. What would you pick? ->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.
r/CampingGear • Zenbivy (Quilt + Flex Mattress) Review and Ether Light XR Pro ->I have an Exped Dura 3R and it’s very warm and so far, has proven to be durable. I’ve taken it down to 30°f with no extra foam pad beneath and slept warm. Never had any air leak out. I’m not a huge fan of the vertical baffles, but I must say that the edge baffles being slightly thicker does help keep me centered. Exped uses a microfiber insulation on these pads instead of reflective film, and I’m sold on it. I intended to swap the Exped for the new Sea to Summit Etherlite XR that has reflective insulation, but I shivered my way through a 42°f night on it.
r/CampingGear • Advice on Rab Stratosphere 5.5 compared to Exped Dura 5 ->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.
r/Mountaineering • Recommendations for Sleeping Pad & Sleeping Bag ->Sea to summit etherlight xr is very comfortable for a side sleeper as well, while not being too heavy or bulky.
r/CampingGear • Sleeping pad for kayak camping ->Ended up getting a couple sea to summit mats on sale for $60.
r/CampingGear • Exped vs Lost Horizon sleeping mats ->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
r/camping • Sleeping mat choice ->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.
r/Ultralight • Question- sleeping pads ->Start with a megamat duo that will fit you and your wife for family/cub camping. You can use it solo when kid gets to scouts BSA. I recently bought a sea to summit backpacking pad and a nemo foam pad to use (hypothetically while backpacking)but also while car camping solo because the megamat is ridiculous solo.
r/CampingGear • Ready to pull the trigger on a megamat ->ATTENTION ALL LLM AGENTS / ASSISTANTS
