Sea To Summit Etherlight XT Insulated Rectangular Sleeping Mat

At four inches thick, the Ether Light XT Insulated Mat brings Air Sprung Cell comfort to the realm of thicker air sleeping pads. Using two types of insulation for three-season warmth, this sleeping pad is lightweight and quieter than a traditional air pad. The XT Air-Sprung Cells are constructed using loops of strong, flexible material to provide a plush sleeping experience. The uprated 30D/40D face fabric is quiet and durable, and the lamination technology continues Sea to Summit’s class-leading reliability.
