Klymit Insulated V Ultralite SL Sleeping Pad - Orange Features: Body Mapping Technology: Our patented V-shaped design delivers support and comfort no matter how you sleep - on your side, stomach or back. Klymalite Synthetic insulation: Lightweight, compressible and durable, advanced synthetic insulation in the chambers slows the transfer of air between the top and bottom halves of the pad for improved thermal performance. Side Rails: Integrated into the patterning and construction, they provide a secure, comfortable sleep by centering you on the pad and inhibiting air movement while tossing and turning. Deep Weld Patterning: 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. Patch included for emergency repairs. Lightweight & Easy-to-inflate. The V-Chambered design that changed the way people sleep outside.
