Sea To Summit Ether Light XT Extreme Air Sleeping Sleeping Mat

The Sea To Summit EtherLight XT Extreme Air Mat redefines sleeping comfort for winter adventurers, featuring an R-value up to 6 and a 10cm thickness due to their Air Sprung Cells technology. Each Air Sprung Cell is designed to independently adjust to the contours of your body, promoting even pressure distribution for improved comfort and support.

To reach the height of the extreme thickness (XT) EtherLight sleeping mat, many TPU loops are used to couple the top and bottom fabric layers to the Air Sprung Cell dot weld pattern. These loops allow the top and bottom layers to be positioned further apart which creates larger pockets of air when inflated—perfect for side sleepers.

This design also requires less fabric overall which means great stability and comfort for less weight. Dual-density layers of THERMOLITE insulation fill the Air Sprung Cells and work together to prevent convective heat transfer and boost warmth while remaining lightweight and packable. When the mercury drops, the EtherLightXT Extreme’s 6.2 (women’s 6.3) ASTM R-value will keep you cushioned and insulated from the cold hard lumps and bumps beneath.
