Klymalite™ lofted synthetic insulation creates additional warmth that lasts through the night. Take on cold conditions without sacrificing comfort or pack size. Klymalite™ lofted synthetic insulation in the pad offers exceptional warmth without the dreaded crinkle noise of other insulated pads. The exclusive V-Chambers and dynamic side rails also limit the movement of air, helping warmth stay closer to the top of the pad—meaning closer to you. Features. DESIGNED FOR YOU: Our patented V-shaped design delivers support and comfort no matter how you sleep – on your side, stomach, or back. STAY CENTERED: 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. EXTRA WARM: 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. With the new Flip Valve.
