Sea to Summit Ultralight Self Inflating Mat Sleeping mat (X-Small, orange/red) - The Ultralight Self Inflating Mat from Sea to Summit is ideal when you want to keep things light! The mat is made of ultralight 30D polyester with laminated TPU. By employing the vertical Delta Coring method, Sea to Summit was able to reduce the weight of the polyurethane foam by 20%. In more stressed areas, such as the hips, shoulders and feet, the delta cores are smaller to guarantee optimum thermal insulation. In less stressed areas, the cores are larger to minimise the mat's weight and pack size. The anti-slip print on the surface and base of the mat keeps the mat and your sleeping bag in place, preventing you slipping off in the middle of the night. The Ultralight Self Inflating Mat is a self-inflating sleeping mat that won't weigh you down on your next adventure!

I used the pad about 6 times before it got a hole and would deflate by morning. I should also mention that I'm pretty uptight when it comes to my gear and I treat it really well--i.e. this is not a user error. I tried finding the hole but was unable to do so. Still it would deflate at home when I left it alone overnight. I'm returning it.Otherwise, it was easy to inflate, very comfortable. Other reviewers were right in that it's a real pain to get it in the bag it comes in. Unless I can find another pad at this price point, I might get it again and give it one more chance.

I wish I can love it, but it came with the security tag. I went to a department to try and get it removed and they couldn't do it. The guy literally said, where was this from and that in California they didn't have that strong of magnets?? So now I am watching countless Youtube videos to figure out how to remove it. I've already made some small holes in the bag trying to break it.Other than this issue, the pad seems great, easy to roll up and perfect for my size. I'm excited to use it for camping.

I bought this sleep pad 15 months ago and used it for three nights. It worked as expected. Just took it with me on a second trip for a three week Colorado River trip and it went flat the first night. Not cool. I've got the patch kit, but finding the leak is impossible. Of course, I'm past the return window.

This pad is a good pad but not the best there is.It is light, it rolls up to a decent size, and it has cushion. However, in my use it doesnβt self inflate well and is very firm to sleep on. The pros are the rubber grips keep it from sliding around in the tent and it pairs well with other sea to summit sleep system products. I give it 3 out of 5 because it could pack down smaller and be more comfortable.
All the reviews had great things to say about this mat; however, it did not back down as small as I was hoping (it's probably the size of a 2L nalgene). I returned for the Sea to Summit Ultralight Insulated pad and was very pleased.
Little bit heavier than insulated one but less noise. I choose particularly Self Inflating one as previous Insulated one (not s2s but non brand) deflated first day of a week bush walking trip, couldn't find a hole to fix. Also Small size 170cm is the best for my height 165cm. I'm very happy with my purchase.
I bought this thing for bike touring. My first our out with it was amazing. The first night I stealth camped and ended up in a clearing with tons of thick vines and roots. This thing was so comfortable even on all those roots. The next night, I was in down town buffalo, and could only crash in a friends back yard due to the pandemic. The yard was just fenced in concrete. This pad again did the trick. i could hardly tell i was on cement.The only recommendation i have is to get a dry sack. Sleeve it comes with is great, but i rode 6 hours in a thunderstorm, so some water was able to leak in.Other than that, great purchase.
I needed an affordable pad to fit inside my sleeping bag for hammock camping on the now and affordable. I'm 5'5" and this went into my small sized mummy bag perfect. Combined with my down fill 20 degree Kelty I stayed warm wearing a base layer at 39 degrees. I had a little of that shoulder/side arm hammock chill but the rest of me was toasty warm. I saw the one star review stating the stuff sack was too small and made it my mission to prove them wrong, because of that I had it rolled so tight it went in the bag with room to spare. So if you actually take the time to roll it right, the stuff sack is perfect. I like to keep my volume as low as possible so I'm pleased with this unit.
It's light with low volume mattress for self-inflating. Very good R factor and so comfortable. Three seasons mattress perfect for camping, hiking and outdoor activities.
sleeping pad is made of sturdy material, no worries of puncturing. It inflates quickly, in about 9 big breathes. It packs small, half the size of the accordion foam mats. cons are it isn't any thicker than the cheap accordion foam mats and weights nearly twice as much for no extra comfort. for the price you would get much better value from the foam matts from a backpacking point of view. I am 6'4" the large mat is only just long enough.
