  • Works well as long as you’re laying down
Style: Large (78 x 25 x 2 inches)
Yeah, it works well when you’re laying down. Weird point to raise with a sleeping pad I know, but if you try and just sit on it, it doesn’t work as well because the air displaces to other parts of the pad that aren’t under pressure.

  • Great for Backpacking
Style: Women's Regular (66 x 21.5 x 2 inches)
I got this for a friend who was hiking the Wonderland Trail around Mt Rainier and had problems with the insulated pad she brought with her. We met at a break in the trail and camped together for a night. She said it was the best night's sleep she had all hike. It's easy to inflate, lightweight, warm and packs up small. Best of all, it doesn't make noise when someone shifts position which is a big deal when you're spending 10 days hiking with someone in a small two-person tent! ... show more

  • Disappointed and a little heartbroken
Style: X-Small (50 x 21.5 x 2 inches)
Used this sleeping pad on the continental divide trail. Was flawless for the first 50 nights. After that I regularly slept on the ground by morning and tried to patch pad in every town I stoped in. Soon the pad gave me a complete failure as a 3” rip appeared as I was inflating it one night. All the failures were on the sleeping side of pad and not on the ground side. Sea to summit if you see this know I’m not mad, just disappointed. You used to be my go to for much equipment. now you are as an old lover who lost their way and forced me to move on. ... show more

  • Works as stated
Style: Regular (72 x 21.5 x 2 inches)
Haven't used it yet but I'll be using it for camping and it is easy to inflate and deflate and packs small.

  • From Store to Landfill
Style: Regular (72 x 21.5 x 2 inches)
Second trip with this pad it started losing air around the fire on a multi-day BC trip. I pumped it back up before bed, and within 5 mins I was flat on the cold hard ground. NOT COOL. Stick with Thermarest. These flim flam pads blow.
