The Traverse Core Mummy sleeping pad from JR Gear is designed to provide really good sleeping comfort due to 8.9 cm. thick transverse tubes. Built-in Infrared Reflective Technology (IRR) coating on the inside, which improves insulation by reflecting body heat. The sleeping pad is made with cut-outs and rounded corners that reduce weight. Note that a pump is not included for this sleeping pad, in which case you can buy it if you wish.
