  • Features

    • Thermoplastic polyurethane-laminated loops connect top and bottom dot welds, resulting in greater thickness at lower overall weight than other pads
    • This eXtra Thick (XT) loop construction and the Air Sprung Cell™ construction work like the springs of a pocket-sprung mattress to deliver supreme support and comfort
    • THERMOLITE® insulation offers warmth with an R-value of 3.8; most sleeping pads we sell range in R-value from 1.0 (minimally insulated) to 9.5 (well insulated)
    • Exkin Platinum® thin metalized layer reflects warmth back to you to minimize radiant heat loss
    • Lightweight, quiet and grippy 30-denier x 40-denier nylon fabric is easily field repairable with the included self-adhesive patches
    • Liquid-extruded thermoplastic polyurethane (TPU) bonds permanently to shell fabric, virtually eliminating delamination
    • Ultra-Fresh® antimicrobial treatment added to the TPU helps prevent mold issues caused by warm, moist air trapped inside the mat
    • Low-profile, high-volume multifunction valve allows fast deflation without fighting re-inflation as you go
    • Includes an Airstream™ pump that's integrated into the stuff sack for quick and easy inflation
    • PillowLock™ attaches your Aeros™ pillow to your mat, holding it in place so you don't lose it in the night (pillow not included)
