The Sea to Summit Ether Light XT Extreme Mat offers increased insulation and warmth for colder camping expeditions and builds upon the popular Ether Light XT Mat.

Featuring air-sprung cells that provide a comfier base, where each air cell deforms independently and contours around your body shape, the Ether Light offers support and comfort by displacing your weight across the mat's surface. Boasting an R-value of over 6, the Ether Light XT Extreme Mat is 10cm thick and redefines lightweight sleeping comfort in colder conditions.

The 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. The use of TPU loops, and the mat's Air Sprung Cell dot weld pattern, allows the top and bottom layers to be positioned further apart creating larger pockets of air when inflated, ideal for side sleepers.

The Extreme has everything you need to keep warm in challenging conditions making it the perfect mat for your chilly winter trip.
