Sea to Summit's lightest, thickest and quietest sleeping mat with full Air Sprung Cells and insulation for year-round use. With the EtherLight XT Air Mat, we are setting a new standard in ultra-light and comfortable air mats. The Ether Light XT combines an extra lightweight 30/40D nylon fabric with Exkin Platinum and Thermolite insulation and Loop Baffle Air Sprung Cell construction. The result is a 10 cm thick mat with an incredibly low weight.Ether light - Single layer designMany interconnected TPU chambers create large air cores that are sealed at the top and bottom with the Air Sprung Cell spot weld. These generously connected chambers position the top and bottom layers further apart. This in turn means less material/weight.ThermoliteThermolite insulation, engineered for ultimate performance, is made from special fibers that allow for a high CLO value at a low weight. Thermolite HL-1 High Loft insulation is a textile fiber fill made from unique 3D ruffs with solid and hollow core fibers that combine outstanding lightweight warmth with excellent durability. The Thermolite insulation spreads within the Air Sprung Cells to prevent convection heat loss from the warm body to the ground. To produce the best possible effect, a combination of Exkin Platinum and Thermolite is used in all versions of the insulated sleeping pads.Exkin PlatinumExkin Platinum is a super lightweight, silent material with a thin metallic surface. Exkin Platinum Thermal Technology reflects radiated heat back to the user. - Category: Thermal Air Mattress - Details: - Includes Airstream Pump Sack - Extra-thick Air Sprung Cells - Lightweight, quiet and non-slip 30/40D nylon fabric - Material repairs easily with included self-adhesive patches - Exkin Platinum and Thermolite insulation - Ultra-Fresh antimicrobial TPU treatment reduces the risk of mildew - Integrated PillowLock attaches Aeros Pillows to sleeping pad - Air Sprung Cells for a comfortable night's sleep - Multi-function valve - Feature: Pack & carry bag included Material - Coating outside: TPU - Outer material: 100 % nylon Dimension - Length (cm): 201 cm - Width (cm): 64 cm - Thickness: 100 mm - Mat thickness: comfortable - Pack size (cm): 12 x 28 Mat & Mattress - Type: thermal air mattress - Type: extra long Performance - R-value: 3.8.
