Quick overview

Fully insulated, extra thick air pockets are created by using many TPU loops that connect the top and bottom fabric layers with Sea to Summit's Air Sprung Cell™ dot weld pattern. By filling the Ether Light XT Extreme mat with dual density layers of THERMOLITE®, Sea to Summit created a line of lightweight mattresses that can be used in the most extreme conditions. Thanks to its lightweight construction, you won't break your back carrying it around.
