After 17 nights, I can tell you I slept like a baby every night. Other hikers commented on the noise it made when I turned over but all of the positive aspects outweigh those peoples comments :) 290lbs 6'2" and this pad works perfectly for me.

Poor quality
Josh3 years ago
I work as a wildland firefighter and bought this at the beginning of fire season last year. When I saw the included patch kit I should have realized how low quality this is. This thing gave me a good night sleep for about two nights before it began gradually deflating every single night. The fact that they included a patch kit suggest they knew this was a terrible product and was not going to hold up, they only included two patches and by the end of the fire season I had a half a dozen. This item was only either in my tent or in my pack the entire season and 6 of the seems managed to pop leaks. For the price I could have bought four of the lower quality ones and I would have slept much better throughout the work season. To end on a high note, the air filling bag is a cool feature but not enough to redeem the product

Mass Manufacturer's Defect
9 months ago
I bought two of these air mattresses and both had persistent leaks all on the welded dimples all oriented the same way and on the same side of the air mattress, indicating a manufacturing defect with the welds. Reached out to Sea to Summit about it, they eventually sent me two new ones... and alas they had the exact same problem! This model of air mattresses by Sea to Summit appear to me to have a mass issue with the way they weld them in Taiwan and I urge all interested buyers in avoiding this model! To top this disappointment off, after contacting Sea to Summit about this problem a second time they asked for the production batch number and haven't returned my emails since then. Its been over 3 weeks and they've ghosted my every communication. Don't buy this product, go with a tried and true thermarest instead.

Sleep like your at 4 star Hotel

[This review was collected as part of a promotion.] This is my 2nd Sea to Summit sleeping pad. A slight upgrade for myself. I found the Etherlight to be quieter, a plus for my girl who thought the other pad initially sounded like a chip bag on every movement. So great job on making a thicker, quieter, more comfortable pad. I gave up a few ounces to get the extra inch of "loft" but occasionally I turn on my side and this pad is awesome. I no longer worry about my hip or pelvis laying on hard ground. The adjustable air valve let's me fine tune for any terrain. Super easy to inflate in just a couple minutes with the stuff sack attached air below. The wide air release valve assures we get out of camp and back on the trail quick. There are similar options available, but Sea to Summit does an amazing job and I have always had a good sleep with no worries about performance or durability even on multi week backpacking trips.

[This review was collected as part of a promotion.] Unbelievably light. Packs small compared to my prior insulated pad. Very warm! Used in two snowstorms so far and was very warm with a 10 degree sleep system.

Defective Product Sad Times
1 year ago
Used for 42 nights on the Tour Divide (GDMBR) Read the reviews that have used the mattress more than 10 days and you will see they had the same issue as mine. Nine air leaks in the top of the mattress where the aircell buttons are. All leaks are on the top of the mattress. Same with other reviews. This is not cool. I lost a lot of sleep blowing this thing up throughout the night on many nights.

[This review was collected as part of a promotion.] Took this with me for 30 miles on the 100 mile wilderness in Maines Appalachian trail segment. Easy to inflate, great insulation, and packs easy. Used in temps ranging from single digits to 20F. Highly recommend for winter use!

Better than most
3 months ago
[This review was collected as part of a promotion.] Very comfortable. Are there other pads that do other things? Yes. Is a sleep pad perfect for one person, and less perfect for another? Also yes. My wife uses a rapide, and I use the etherlight. Both are extremely comfortable, and both are surprisingly very different via their sound, feel, and overall warmth delivery. I'm not saying this one is for you, but it is better than a bunch of them. It's been a durable companion that delivers the ZZZ. Worth checking out. Oh! And I love the inflation/stuff sack. That is actually a step above the competition. Not the best thing for the UL community, but you guys will just use your breath anyway. 😅

Warm but noisy
2 years ago
If warmth is your critical factor this pad works great. It also is contoured and works well with other sleep systems like Zenbivy sheets. My biggest complaint is how noisy this pad is. It's literally the squeakiest of all the various pads I've owned. I even later bought a bag liner to put over the pad to reduce friction with the tent bottom and sleeping bag bottom but it didn't help much. It sounds like one of those cheap styrofoam egg cartons all night long. But it is warm and keeps you off the ground high enough to not feel rocks and roots. I think if the surface was flat rather than dimpled, it would be much quieter when pressure is applied.

great pad, great inflation system, horrible stuff sack.
4 years ago
I've really enjoyed this pad - thick, warm, and quiet. The inflation system of using the stuff sack is great and easy to use. Awesome for side sleeper and light too However the stuff sack is really too small for the size and its my biggest gripe. Granted I have the largest size version, but I'm not sure if the sack is the same size for all, so who knows if the issue is same for smaller sizes. facts is you need to roll your pad just the right tightness and pray their inst a spare air molecule between it and the sack. Otherwise you're gonna be rerolling and hope the packing gods smile upon you. great product, love it, stuff sack is awful.

Quiet & Cushy

The limited use I have had so far with the ELight XT has been very positive. Looks to be very durable and love the weight to R value ratio. I think even coupled with a rigid foam pad it could be very useful deep into the shoulder seasons if not some winter use with the right sleeping bag and liner system. I love the Reg Length/Wide size availability as I tend to be a toss & turner (roll off a narrow mummy shaped pad easily) and use wide sleeping bags to help with side sleeping. Very impressed with the inflation bag system. Much better than another (Swiss made) bag inflate system i have with a double width pad i use when backpacking with my wife.
