Shaped specifically for cold-weather women adventurers, the extra-thick Women's Ether Light Extreme is constructed with additional insulation compared to the unisex model. The XT Air Sprung Cells provide four inches of stability and comfort, while increased-density dual layers of THERMOLITE insulation prevent convective heat loss and internal air movement.
