Sea To Summit have taken their best selling mattress and increased the insulation for when the mercury drops.
With an R-Value of over 6 and 10cm of thickness the EtherLight XT Extreme Air Mattress redefines lightweight sleeping comfort for winter explorations and adventures around the globe!
Sea to Summit’s Air Sprung Cells are the reason they believe you will sleep better on their air mats. Each Air Sprung cell deforms independently and allows the mat to conform to your body shape. This provides support and comfort by more evenly dispersing pressure across the mats surface.
For the extra thick (XT) Etherlight design, Sea To Summit use many TPU loops to connect the top and bottom fabric layers to the air sprung cells 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.
When the mercury drops, the Women’s Ether Light XT Extreme’s 6.3 (Unisex/Mens 6.2) ASTM R-Value will keep you cushioned and insulated from the cold hard lumps and bumps beneath.
