A small sacrifice.

You'll have to ditch the camping comforts if you want to backpack in higher altitudes, but if you're willing to sacrifice some packing space and about thirteen ounces, then Sea to Summit's UltraLight SI Sleeping Pad will make a world of difference. The difference, of course, is enjoying gigantic granite cirques, lush vegetation, and rocky summits with or without a sore back. This self-inflating pad cradles specific areas of contact—hips, shoulders, and more—with Delta Core-V technology to keep your back prime for the climb.
  • Packable sleeping pad suitable for alpine backpacking
  • Delta Core-V ensures warmth in contact areas
  • Self-inflating design with multi-function deflate valve
  • Item #STS004B

Good for the money

I've used it several times

This review is based on someone who is 255 lbs and on the shorter side. The mat was easy to set up and had good support. I went on a bike packing trip with this pad and while I did sleep a little, I don't know what it was that was, but I was uncomfortable. This is not the first trip I have been on at this weight. Last time I used a Therm-a-Rest pad and I slept like a baby. It was about half the price of this one. It does the job though, as I do not like feeling the ground beneath me. I even had to sleep on rocks at one point and I did not feel them beneath me. This pad held up very well. A little difficult getting it back in the bag that it comes with but if you go slow, it will go back in the bag. Overall, it was a good lightweight and compact sleeping pad.

great pad!

It's just thick enough to where my bony hips don't touch the ground while I'm sleeping on my side. Takes one breath to fill up if you let the foam do it's work first. Fits back into stuff sack easily.
