REI Co-op AirRail Self-Inflating Sleeping Pad

REI Co-op's AirRail self-inflating sleeping pad pairs a self-inflating, insulated open-cell foam core with large insulated air rails on the outside to keep you from rolling off during the night. Its 4.2 R-value delivers 3-season warmth and considerable insulation from ground temperature.

The tapered mummy shape reduces weight and packed size, while the contoured side rails are ergonomically shaped to support your body and maximize sleeping comfort. The durable 75-denier polyester top has an embossed nonslip surface and the 75-denier polyester bottom resists wear, with all seams welded. Separate high-flow, color-coded inflation and deflation valves make setting up and breaking camp frustration-free, and the pad comes with a repair kit and a stuff sack.
