Cleverly constructed comfort for the coldest conditions
The Ether Light XT Extreme is extra thick and exceptionally warm. The XT Air Sprung Cells provide 4" of stability and comfort, while dual-density layers of THERMOLITE® insulation prevent convective heat loss and internal air movement. The result: true four-season performance.
Best Use: Backpacking in cold weather or winter conditions
Air Sprung Cell construction makes the Ether Light series more stable than other similarly thick air pads for greater comfort.
Liquid-extruded lamination forms an extremely reliable airproof barrier. The laminate and RF welds are engineered for years of trouble-free performance.

Suitable for backpacking? Possibly. The Tapered Regular weighs 25.5 ozs / 720 g – a little heavy for warm weather backpacking, but fine for backpack trips in cold-environments.
