The ALPS Mountaineering Nimble Insulated air pad features a 3D body-mapped design to help keep you from sliding or rolling off no matter what sleeping position you prefer. The TechLoft silver insulation provides an R-value of 4 and is treated with antimicrobials to prevent the growth of bacteria. The included stuff sack features a one-way valve that securely attaches to the Nimble's flat valve, for quick inflation. As with all ALPS air pads, the Nimble series comes with a stuff sack and repair kit.
