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.
