Klymit Backpacking Pads Insulated Static V Luxe Sleeping Pad Red Extra Large 06LIRD02D. The king of cold weather sleep comfort. The biggest warmest most comfortable inflatable pad at around two pounds. It’s 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 that’s wide enough so you can move around without feeling restricted. It even rolls up small enough to easily slide in a backpack.
