Offering cleverly constructed comfort for the coldest conditions, the Sea To Summit® Ether Light XT Extreme Insulated Sleeping Mat offers adventurers true 4-season performance. Extra thick and exceptionally warm, the Ether Light XT Extreme combines extra thick Air Sprung Cell construction with dual-density layers of Thermolite® insulation inside to provide a 6.2 R-Value. Quiet and grippy thermoplastic-polyurethane-laminated 30- and 40-denier nylon shell reduces overall weight while maximizing durability. The shell's liquid-extruded lamination forms an extremely reliable airproof barrier, with RF welds engineered for years of trouble-free performance. This durable laminate also features microbe-resistant treatments to resist internal mold growth over time. More stable than other thick air pad designs, the Air Sprung Cell construction offers 4" of warm and stable comfort. The mat's multifunction valve makes it easy to inflate the bag to your liking, and then allows the mattress to be rolled tightly without fighting re-inflation as you roll it up. PillowLock™ design is compatible with Sea to Summit Aeros™ Pillow (not included). Includes Airstream™ Pump/Stuff Sack and repair kit.
