The Sea to Summit Ether Light XT Extreme Cold-Weather Insulated Air Mattress is an extra-thick and extra-warm 4-season sleeping pad for winter backpacking and camping. Its Air Sprung Cell construction mimics a spring mattress, maintaining more body contact area and even dispersion of pressure for restful backcountry slumber. At 4 inches thick, the sleeping pad features a single-layer design with fully-insulated flexible loops, providing a plush, warm sleeping surface. The multi-function reversible valve allows for fast and easy inflation—with the integrated Airstream Pumpsack which inflates the pad in just a few breaths—one-way deflation for quick packup, and fine-tuning of air pressure for a good night’s sleep. The insulated pad features Thermolite insulation which lofts up inside the Air Sprung Cells to prevent convective heat loss to the cold ground, as well as Exkin Platinum reflective fabric which radiates heat back during sleep (R-Value of 6.2—the higher the R-value, the warmer the sleeping pad). Non-slip 30D/40D nylon face fabric is durable and quiet. The Sea to Summit Ether Light XT Extreme Cold-Weather Insulated Air Mattress is available in four sizes: Tapered - Regular measures 72 x 21.5 x 4 inches, packs to 6.9 x 9.4 inches, weighs 1.6 pounds; Tapered - Large measures 78 x 25 x 4 inches, packs to 7.3 x 11 inches, weighs 2.1 pounds; Rectangular - Regular measures 72 x 25 x 4 inches, packs to 7.3 x 11 inches, weighs 2.1 pounds; Rectangular - Large measures 79 x 25 x 4 inches, packs to 7.3 x 11 inches, weighs 2.3 pounds.
