Product details:

With an ultra-lightweight design, the award-winning Therm-a-Rest NeoAir XLite inflatable sleeping pad is built for ounce-counting backpackers. The mattress utilizes an integrated truss system and a heat-reflecting interior to achieve a 4.2 R-value at less than a pound. Unlike the limited number of vertical baffles employed by most traditional inflatable pads, the NeoAir XLite utilizes horizontal air baffles. While minimizing convective cooling, Therm-a-Rest's Triangular Core Matrix technology and the increased number of baffles help to increase stability and avoid the 'inflatable raft' feeling caused by overinflated vertical baffles. In addition, a patent-pending internal reflective barrier actually directs heat back to your body and cold air back to the ground The inflatable construction provides a full 2.5' thick support base. Ultra-lightweight, high-tenacity materials offer durability while maintaining an incredibly light packed weight. The pad can be quickly and easily inflated with the use of an included pump sack and the one-way WingLock valve. This saves you the work of inflating by mouth and keeps potentially damaging moisture from entering the pad. The Therm-a-Rest NeoAir XLite sleeping pad is available in Small (20' x 47'), Regular (20' x 72'), Regular Wide (25' x 72'), and Large (25' x 77') sizes. A pump sack, stuff sack, and field repair kit are all included.
