Thermarest xtherm pad - Therm-a-Rest NeoAir XTherm NXT MAX Sleeping Pad

Got the large. 77” long, 25” wide, 3” thick. Weighs about 1.6 pounds. Blows up with accompanying sack. Takes a while to blow it up. R value of 7.3. I don’t know what insulation is in the pad but it’s warm. I blew it up on the floor, laid down, and I felt the heat under me. Hard to believe this pad is so warm at this weight. I’m not convinced that this pad is durable and it is a little noisy. The pad, blow up sack, patch, and instructions all fit easily in the stuff sack with folding the pad in thirds and rolling lengthwise. The pad seemed comfortable at 3 inches thick. Can’t complain, a 4 season pad that weighs 1.6 pounds. It will nice to have one pad for backpacking regardless of the weather. Hope it holds up.
