Sea to Summit Ether Light XT Extreme Insulated Mat (Large)

The 10cm thick Ether Light XT Extreme Insulated Air Mat-Large redefines lightweight sleeping comfort for winter trips with an R-value of over 6.2.

The Air Sprung Cells from Sea to Summit are the reason you'll have one of the most comfortable nights sleep. The mat conforms to your body shape since each Air Sprung Cell deforms separately. This gives support and comfort by dividing the weight more evenly.

TPU loops securely holding the top and bottom layers together are designed in a way to allow these layers to be separated farther, resulting in greater air pockets when inflated, which is ideal for side sleepers. This design also uses less fabric in general, resulting in more stability and comfort for less weight.

The Air Sprung Cells are filled with dual-density layers of THERMOLITE insulation that work together to reduce convective heat transmission and improve warmth while staying lightweight and packable.
When the temperature lowers, the 6.2 (women's 6.3) ASTM R-value of the Ether Light XT Extreme will keep you cushioned and protected from the cold hard lumps and bumps beneath.
