Klymit Static V2 Sleeping Pad, 72" x 23 " x 2.5", Green features our patented V-shaped Body Mapping Technology that delivers support and comfort no matter how you sleep - on your side, stomach or back. Side Rails, integrated into the patterning and construction also provide a secure, comfortable sleep by centering you on the pad and inhibiting air movement while tossing and turning. Unlike traditional pads that flatten the bag's fill, the Deep Weld Patterning creates expansion zones that allow your bag to fully loft beneath you for improved thermal comfort.
