Klymit Insulated Static V Lite Sleeping Pad, 72" x 23" x 2.5" (Orange) is a 4-Season Ultralight Sleeping Pad featuring lighter weight fabric for smaller pack size and weight. Provides warmth all year long with a R-Value of 4.4. Our patented V-shaped Body Mapping Technology delivers support and comfort no matter how you sleep - on your side, stomach or back. The Klymalite Synthetic insulation is 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, 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 Weld Patterning creates expansion zones that allow your bag to fully loft beneath you for improved thermal comfort.
