The REI Co-op AirRail Plus self-inflating sleeping pad features a hybrid design that offers low weight, compressibility and sleeping comfort—plus rails to keep you from rolling off your pad.

  • Features

    • Hybrid design combines a self-inflating, insulated-foam center panel with large insulated air rails outside to keep you from rolling off
    • Contoured side rails provide support and comfort, ergonomically shaped to fit your body and maximize sleeping comfort
    • Cross-cored foam insulation is lightweight, compressible and stable
    • Quick-closing, high-flow valves
    • Durable 75-denier polyester top has an embossed nonslip surface; 75-denier polyester bottom resists wear; all seams are welded
    • Tapered mummy shape reduces weight and packed size
    • This pad has an R-value of 3.3, which makes it best for adventures in cool weather; it provides moderate insulation from ground temperature
    • Most sleeping pads we sell range from 1.0 (good for warm weather) to 5.5+ (for use in extreme cold); the higher the R-value, the more insulated the pad
    • Stuff sack included
    • R-value tested according to the ASTM F3340 standard
