Uber comfortable
[This review was collected as part of a promotion.] Super comfortable. I’ve had many designs, but this quilted like pattern makes it super comfortable less noisy than normal and doesn’t need to be a stick to feel comfortable as a side sleeper. The fact that it’s small and light is obviously the reason why I bought it, but I love it because it’s actually really comfortable to sleep on and it has replaced my heavier mat on non-backpacking trips

Sea-to-Summit Short Ultralight Pad
I got the shortest version of this pad because I put my empty pack under my lower legs and feet. I've used it now on 2 separate 3-night trips (to the same location and same sleeping spot of ground) and it's the MOST comfy pad I've had yet. We'll see how long term it lasts but so far it inflates well with the supplied stuff-sack/inflation-bag. I use 1/2" closed cell foam underneath it for protection and more comfort. Overall, I like this a Lot more than my similar Thermarest 3" thick (too thick) short pad because this Sea-to-Summit is more comfy, and less tapered (I wish they were all rectangular again!) and the inflation bag snaps on/in a Lot easier. I'd prefer to buy from USA Thermarest but they don't make what I want anymore.

Great
[This review was collected as part of a promotion.] I really appreciate you guys just replacing this for me. I love these pads and will buy them for the rest of my life. Hard to find companies that will just make things right.

Motocampers best friend
[This review was collected as part of a promotion.] Man this bed pad is great, I’ve had it on sand, rock, dirt, roots, and its comfort is amazing for how thin it is. Being completely honest, at 220lb I thought it wasn’t enough until I layed directly flat and some how some way there wasn’t a single pressure point even sleeping on my side! This bed pad is perfect and inflates so easy with the bag!

Not too thick
[This review was collected as part of a promotion.] Dont like 3”+ mats generally because my arms spill off as I move around as a full rotation sleeper. Also have a bivy that can get cramped. This is more than a zlite and less than most and is perfect for me. I use a section of 1/8” clf pad under to keep mat from sliding around in the bivy

Sleeping pad
[This review was collected as part of a promotion.] I updated to this pad for casual camping, backpacking and cycle touring so wanted something that was light, durable but with the highest level of comfort. All of these features exist without compromise.

Doesn’t handle gravel
[This review was collected as part of a promotion.] Went camping and had to set up last minute on the flattest area I could find, on the side of a gravel road. It barely supports your weight, so the moment you lay up right you will hit bottom. I do love sea to summit products but this was a miss for me.

Great Pad
[This review was collected as part of a promotion.] The engineering on this thins is great. The integrated inflation sack and dual action port work great and make for quick inflation and deflation. Pack size is just right and weight is truly UL. I used it in conjunction with a top quilt and was comfortable down to 35 degrees F. Minimal movement squeaking. I would recommend for all your 3 season needs.

Great sleeping pad
[This review was collected as part of a promotion.] I switched to this pad from the neo air uberlite because of punctures and night time deflation. The sea to summit pad is much more durable and being insulated doesn't deflate at night, highly recommended

Great Pad with Great Warranty
[This review was collected as part of a promotion.] Absolutely love the pad, light and warm. When it inevitably got some small holes, the S2S people helped a ton.
