Sleeping pad with Body Mapping technology. Features a patented V-shaped design which delivers support and comfort no matter how you sleep - on your side, stomach, or back. Side rails integrated into the patterning and construction 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, Deep Welds create expansion zones that allow your bag to fully loft beneath you for improved thermal comfort. Anti-microbial laminate permeates the inside laminate to inhibit the growth of microorganisms, including fungus and , that can cause odors and material damage. Patch included for emergency repairs.
