Comfortable

[This review was collected as part of a promotion.] It's relatively easy to inflate, comfortable to sleep on and fairly quiet. I am only speculating about the future but it "feels" cheaper than I would prefer. However that's merely opinion from comparing it to my 25 year old therm-a-rest.

Super comfy

[This review was collected as part of a promotion.] Super cushy. Able to lay on my side without my hip hitting the ground. Lightweight. Packs down great. Very happy with this purchase.

Great Pad

[This review was collected as part of a promotion.] My dad got this sleeping pad for me for my 21st birthday. I am going on tour with an indie band and this is an unexpectedly great and comfortable solution for crashing at people’s apartments when they don’t have 6 extra beds for the band. I recommend it to more musicians who are going on the road. It is comfortable, my bones don’t touch the floor, and fits in the car or plane with a bunch of other music gear. I will also use it outdoors in the future.

Amazing sleep upgrade

[This review was collected as part of a promotion.] The Ether Light XR is a great upgrade to my previous sleeping pad. This pad is super comfortable, packable, and warm. Even though I bought the rectangular wide pad, it is still amazingly small. Also, I love the integrated pump on the sleeve that makes pumping up the sleeping pad super quick and easy. I love that it is integrated right into the sleeve so you can't lose it. I have tried a lot of different sleeping pad brands, and I think the Sea to Summit pads are the best backpacking pads you can get.
