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.
