"is water proof ... it’s going to last me much MUCH longer than a 20-30$ foam mattress topper will, because it’s meant to go outside and be exposed to the elements."
"I've had a sea & summit dual-chamber pad for 8 years or so, never had a leak ... We live in CO and go camping 8-10x a year, for 3 or 4 day weekends each time."

"Or if it's little seam weld pinholes, take advantage of the warranty (I use Sea 2 Summit pads mostly). ... 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) ... 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. ... I talked to someone at Sea to Summit once who said that those type of failures are not due to external puncture/abrading but actually weaknesses that can occur when the seam welds are done that get exacerbated/worse over time. Typically they occur under the torso/arm area and are due to more contact from elbows specifically. ... sometimes (like quilted/dimpled baffles) the pads are just prone to little defects that emerge the longer the pad is used that no amount of babying can prevent. ... No matter how much you baby your sleeping pad, if it has a weak valve attachment, it's gonna develop a leak."

Sea-to-Summit Comfort Plus Insulated. It is a dual-chamber sleeping pad, so you can tune the bottom chamber to provide protection from the ground and top chamber to give you the right level of cushion. None of the other pads on the market can do this, including celebrated Therm-a-Rest and Exped offerings. Exped Megamat is still more comfortable, but it won't fit inside a kayak and weights a lot more. S2S Comfort Plus is the next best thing.
r/CampingGear • Sleeping pad for kayak camping ->I have both of these coincidentally. The plan was to take my Insulated on trips I’m packing light, and my Large S.I on trips where weight/size isn’t a factor. Both comfortable, but I personally enjoy the SI’s flat surface over the Insulated with their Air spring design. The SI has a R value of 4.1, and the insulated 4.0 so they’re basically the same for warmth. If size wasn’t a factor I’d go S.I if I had to choose one. Can’t go wrong with either one of these IMO
r/camping • Self inflating foam pads vs insulated air sleeping pads ->I've had a sea & summit dual-chamber pad for 8 years or so, never had a leak - my wife has a lighter, single chamber pad and also hasn't had any leaks in the same timeframe. Could just be you're getting cheap pads...
r/Ultralight • My sleeping pads never seem to last more than a few months ->I'd go for the insulated one. That "air sprung cell" structure is pretty much the comfiest I've ever tested, and going from self-inflatable to airpad was a big upgrade in sleeping comfort for me, even with another brand.
r/camping • Self inflating foam pads vs insulated air sleeping pads ->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.
r/CampingGear • Best cold weather mattress that’s NOT an xtherm ->Check out the Sea to Summit Comfort Plus XL - it's literally designed for bigger folks. The dual air chambers prevent you from bottoming out when side sleeping (i'm also a side sleeper at 260lbs). Usually around $199 but goes on sale sometimes and packs down surprisingly small.
r/CampingGear • Big Guy needs help picking a backpacking sleeping pad. ->exped megamat 10 big agnes captain comfort deluxe sea to summit comfort plus insulated
r/CampingGear • Sleeping pad suggestions ->I'm pretty much exactly like you. Tried and DONT LIKE: Therm-a-Rest NeoAir Topo Luxe. It's thick! But the horizontal baffles suck for side sleepers. Sea to Summit Comfort Plus Insulated. Not thick enough. Hip pain. Noisy. The one I want to try next: Therm-a-Rest NeoLoft.
r/camping • Sleeping Pad Recommendations ->I have the sea to summit comfort plus sleeping pad. It’s rated at an R4, while a foam pad like you’re describing is only rated R2. It’s under 3lbs, easily rolls up and is packed into a tiny bag so it’s easy to transport around, takes up very little space, auto inflates, is water proof and has a memory foam interior for comfort and warmth. On top of all of that, it’s going to last me much MUCH longer than a 20-30$ foam mattress topper will, because it’s meant to go outside and be exposed to the elements.
r/camping • What are you getting with a $200+ sleeping pad ->I’m a side sleeper as well and I stopped using my Nemo tensor so much because of the potato chip bag noise effects heh. This past winter, I’ve used the Sea to Summit comfort plus. It is easily the most comfortable pad I’ve ever used for side sleeping. And inflates and deflates easily. Highly recommend!
r/REI • Looking forward the unicorn of a sleep pad. Quiet. Side sleeper. Lightweight ->I'm a big fan of the sea to summit pads. If I was buying now I'd buy the comfort plus. 6'5" 250ish side/stomach sleeper
r/CampingGear • Big Guy needs help picking a backpacking sleeping pad. ->Plus comfort and packability. The foam pads typicially have R value of 2 and weigh about 1.4 kg/3 lbs. One could construct the equivalent of R4 by stacking 2, at a cost of about $50-60, giving a weight of 6 lbs. The Sea to Summit Comfort Plus with an R4 rating is $178 at REI. It's just under 2 lbs. You could save $120 at the cost of 4 lbs, a huge increase in bulk, and a worse night's sleep
r/camping • What are you getting with a $200+ sleeping pad ->I had the same challenge recently, as in buying my first pad. I went with Sea to Summit comfort plus in the end. Paid 70 quid with delivery. I tested it in a 2 day camp and was impressed by the quality and “warmth”. But it is to the heavy/bulky side.
r/wildcampingintheuk • Sleeping pad recommendations for a beginner ->I recently got a Sea to Summit comfort plus and used for the first time at 1 degree and I was nicely warm. I got it for around 70 quid. It is to the heavy side though and in the summer I intend to buy a light mat but for the price I was very impressed with the quality and warmth.
r/UKhiking • Sleeping mat recommendations ->I have the Sea To Summit comfort plus. It’s nice and thick and not too heavy.
r/wildcampingintheuk • What’s your go-to sleeping pad for rough or uneven ground? ->I like the sea to summit comfort plus. Though I've heard good things about their comfort delux pad and the brand Exped is mentioned a lot as well.
r/camping • Self inflating mats? ->If you haven't tried self-inflating pads you should give them a shot. I hate sleeping on air mattresses or inflatable sleeping pads, and self-inflating feel much more like a real mattress. It's a combination of foam/air, also helps if you don't inflate it all the way. Sea to summit has a whole line including the comfort and comfort light which I've used and I think are great. I've also used a cheaper REI branded one and ALPS mountaineering version and found them just as good.(Only difference being the cut which shaves weight instead of just a rectangle.) They are heavier than what everyone seems to want to go for, but they have better insulation properties than inflatable and in case of a puncture will still have some comfort.
r/WildernessBackpacking • How much better are “nice” sleeping pads? ->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.
r/army • Best sleeping mat for the field? ->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 ->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 ->I personally think Sea to Summit pads are comfortable. Nemo Tensor might interest you as well.
r/hiking • Most comfortable sleeping 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
r/Ultralight • My sleeping pads never seem to last more than a few months ->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.
r/Ultralight • My sleeping pads never seem to last more than a few months ->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.
r/Ultralight • My sleeping pads never seem to last more than a few months ->Buy once cry once. Thermarest, Nemo, Sea to Summit. They make the best small, lightweight, comfortable pads.
r/Ultralight • save me from sleeping pad hell pls ->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.
r/wildcampingintheuk • Sleeping Mat recommendations ->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.
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 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!
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? ->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.
r/backpacking • What’s the best self inflating sleeping pad for backpacking? ->Samw with my sea to summit absolutely unbelievable how comfy it is.
r/camping • Air matress vs sleeping pad ->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.
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 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.
r/WildernessBackpacking • How much better are “nice” sleeping pads? ->I have the S2S and love it! Side/back sleeper.
r/CampingGear • Sleeping Pad suggestion ->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.
r/Ultralight • Very poor sleep on the NeoAir X Lite NXT. Recommendations? ->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.
