I just got back from eight days and 61 miles on Isle Royale. My goal was to get my pack weight down to 25 lbs. The Uber-lite helped me accomplish this. Since this is a 3/4 pad, I used my empty pack for my feet and got a fairly comfortable sleep. I do move around during the night, but I found that the pad was comfortable in every position. Don't get me wrong, it's not like your sleeping on a 1&1/2 inch Thermarest, but it's not 2 lbs either.
This pad did exactly what I wanted and I had the lightest pack on the island.
