Light and comfortable

[This review was collected as part of a promotion.] Slept on it for 3 nights and it's the best nights sleep I had on the ground and years. Packs small and lighter than my last pad.

Better than most

[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. 😅

Ether Light XT Insulated Air Sleeping Pad.

[This review was collected as part of a promotion.] It was exactly as advertised. Seem thick enough and easy to inflate. Can’t wait to try it in the west coast trail!

Great for the price!

[This review was collected as part of a promotion.] I bought my girlfriend a big Agnes and it's great so I wanted to upgrade my sleep system as well. I did not want to spend as much as I did on her so I bought this one since they were comparable in size. I slept great and did not experience as much noise as my previous sleep pad. The big Agnes is better but twice the price

Comfy, but I have some complaints

[This review was collected as part of a promotion.] First off I love the weight and the comfort, I do not regret my purchase at all. I have two complaints. The pump sack design, I think is less then ideal. I do not like having to blow into the pump sack to inflate a pad. It gets moisture inside the pad and although it might be a little easier, I think it defeats the purpose of the pump sack, my previous pump sack was tubular not tapered and I love that design. Your pump sack is a pain in the butt, I ended up buying an electric inflator. My second critique, im not 100% sure on the reason but I'll explain it. The first night I used it, I woke up in a flat sleeping pad, but it felt fine before i fell asleep. So it is a very slow leak, which leads me to believe it's a small leak from the valve system, and not a hole. I haven't had a chance to submerge it but if I'm wrong I'll definatly correct my self. So I think maybe some type of turn valve would be an improvement and a better pump sack. I love a pump sack that's the same diameter from the opening down to the valve. But besides that I still use it all the time!

Great so far

[This review was collected as part of a promotion.] After a few weeks of use it is easy to say I like it a lot. Positives: soft, quiet, robust. Negatives. Sewn in air pump, heavy,. Overall it’s a nice air mattress, the real test will be if it holds up.

Good sleeping mat for bigger people

[This review was collected as part of a promotion.] I got the wide, long rectangle since I’m 6’4” 235lbs and it’s long enough to stretch out on without hanging off and pretty comfortable. The outside material isn’t too squeaky but not quite as comfortable as my old school Thermarest (but it is thicker and more plush). Good for side-sleepers. Not the lightest but I think it’s worth the weight. 4. 5 stars out of 5

Comfortable mat, but not for the cold

[This review was collected as part of a promotion.] Love the thickness and the pillow lock works flawlessly with my pillow. The mat, however, could be warmer. Last time I was out it got down to ~2-3 degrees Celsius and I was cold in a mi is 1 bag and PLENTY of layers. No shade on the mat, just get the extreme if you're camping close to freezing temps.

It’s a comfortable pad but…

[This review was collected as part of a promotion.] I did get cold when I slept in 30°F. I was very comfortable tho since I’m a side sleeper and didn’t bottom out. I got the regular wide.
