Sea to Summit Etherlight XT Insulated Air Sleeping Mat

Refining lightweight cold-climate sleeping comfort, this mat combines a lightweight 30/40D Nylon fabric, Exkin Platinum® and THERMOLITE® insualtion with a loop baffle Air Sprung Cell™ construction to create a 10cm thick mat with an incredibly low weight. Larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with our Air Sprung Cell™ dot weld pattern. The looped baffles allow the top and bottom layers to be positioned further apart creating larger pockets of air when inflated that require less fabric overall. Perfect for side sleepers, the extra height of this mat lets hips sink deeper into it without touching the ground.
