Finally, a quiet sleeping pad

[This review was collected as part of a promotion.] After sleeping on crunchy pads by Nemo and Klymit, I decided to give the Sea to Summit model a shot after getting a targeted ad. I put the new pad to work this week during an overnight trip in central AZ. It took me about six casual fillings of the inflate bag to get the pad to a point where I could top it off with a few of my own breaths. The Ether pad pretty much filled my Marmot 1P tent which was fine by me. Despite the 35 degree temps in a well ventilated tent, I felt fully insulated from the ground beneath me. The biggest revelation was how quiet the pad is despite my usual tossing and turning. While the StoS pad is noticeably larger when rolled up than my Nemo pad, it has definitely earned a place in my pack.

Lightweight, But Thin

[This review was collected as part of a promotion.] Pad is lightweight, compact, durable, and easy to set up. However, while it attests to be 4 inches of thickness, it seems thin. Can feel the ground when sitting up or sleeping on side.

Great Pad

[This review was collected as part of a promotion.] This pad seems great! I got it during the winter sale and haven’t gotten the chance to take it outside, but from setting up inside, laying on it, and rolling around, it seems extremely comfortable and durable. Can’t wait to put it to use this spring and summer.

Best ultralight sleeping pad extant!

[This review was collected as part of a promotion.] If a better ultralight sleeping system exists, I haven't found it. It weighs <1lb (. 5k) and packs to the size of a Foster's beer can. Easy to use and completely self-contained sleeping system. Coupled with an Embers 30F down quilt, your entire sleep system weighs 2. 4lbs (1. 1k). You'll be lighter during the day, and nice and warm and comfy at night.

Can't wait to test it it in the field!

[This review was collected as part of a promotion.] This is a huge upgrade from my old bulky thermarest, and my lighter klymit. Seems incredibly comfortable when I blew up at home, and packs really small. Can't wait to test it in the field!

Satisfied customer

[This review was collected as part of a promotion.] The sleep pad worked great for a 4 day trip. I am glad I went with the insulated pad as temps were in the teens. I would recommend to a friend.

Love this sleeping mat!

[This review was collected as part of a promotion.] Love this sleeping mat! I have a herniated disk in my back but don’t want to be limited on my ability to do backcountry hunts. I’ve been testing this pad out and it’s working great and keeping me free to spend nights in the wilds. Thank you for making lightweight gear that WORKS!

comphy but loud

[This review was collected as part of a promotion.] Very comphy, fast to set up and take down. Kept me warm (nights went down to 2 degrees celcius). Good for side sleeping, no pressure points. 4 stars because it makes a lot of noise if you toss and turn.
