SEA TO SUMMIT ETHER LIGHT XT EXTREME SLEEPING MAT

The Ether Light XT Extreme is extra thick and exceptionally warm. The XT Air Sprung Cells provide 10 cm 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. 

For the extra thick (XT) Ether Light design, many TPU loops are used to connect 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.
