Its Air Sprung Cell construction mimics a spring mattress, maintaining more body contact area and even dispersion of pressure for restful backcountry slumber. At 2.5 inches thick, it provides a soft and comfortable 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 pack up, 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 3.7—the higher the R-value, the warmer the sleeping pad). Air Sprung Cells are double layered in the torso for increased comfort and warmth, with a single layer of cells in the head and leg areas for reduced weight. Non-slip 30D/40D nylon face fabric is durable and quiet. The Sea to Summit Comfort Light Insulated Air Mattress is available in two sizes: Regular measures 72 x 21.5 x 2.5 inches, packs to 4.5 x 9 inches, weighs 1.4 pounds; Large measures 79 x 25 x 2.5 inches, packs to 4.5 x 10 inches, weighs 1.7 pounds. Includes stuff sack, field repair kit, and PillowLock patches for securing a Sea to Summit pillow to mat.
