Sea to Summit EtherLightXT Extreme

Ether Light XT Extreme is extra thick and unusually warm. XT Air Sprung Cells provide four inches of stability and comfort, while dual-density layers of THERMOLITE® insulation prevent convective heat loss and internal air movement. This results in true four-season performance.
