Klymits Insulated Static V Luxe sleeping pad is Klymits biggest, warmest, most comfortable inflatable pad at around two pounds. Its incredible what we were able to pack into this luxury pad without going overboard on weight. Klymalite lofted synthetic insulation keeps you comfortably warm throughout the night on a V-Chambered sleeping surface thats wide enough so you can move around without feeling restricted. It even rolls up small enough to easily slide in a backpack.
