Sea to Summit Ether Light XT Mat

Sea to Summit has taken the best-selling Ether Light XT sleeping mat and increased the insulation to make it warmer when the temperature drops. With an R value above 6, the 10 cm thick Ether Light XT Extreme air mattress redefines lightweight sleeping comfort for winter adventures around the globe. The Air Sprung Cell technology is the reason why you sleep better on air mattresses. Each Air Sprung Cell deforms independently and allows the mat to adapt to your body shape. This provides more comfort by distributing the pressure more evenly over the mat surface. For the extra thick (XT) Ether Light design, Sea to Summit uses many TPU loops to connect the top and bottom layers of fabric to the spot welded Air Sprung Cell chambers. These loops allow the layers to be positioned further apart, creating larger air cushions when inflated – perfect for side sleepers. This design also requires less fabric overall, which means greater stability and comfort at a lower weight. Double layers of Thermolite insulation fill the Air Sprung Cells and prevent convective heat transfer from the warm body to the floor, while keeping the mat light and packable.
