Sea to Summit Comfort Light Insulated Air Mattress for Backpacking and Camping, Large (79 x 25 x 2.5 inches)

The Sea to Summit Comfort Light Insulated sleeping mats feature hybrid layer Air Sprung Cell technology - a double layer of high resolution cells in the torso for maximum comfort and insulation, and single layer of medium resolution cells in the head and legs for reduced weight. Air Sprung Cells are small, point-weld divided air chambers which individually absorb pressure and conform to the contours and movement of your body without affecting adjacent cells. The result is a mattress that supports you better than one with ‘tubes’ or ‘baffles’. Sea to Summit uses Exkin Platinum, a quiet non-woven fabric, to reflect radiant heat loss back to the user and Thermolite insulation to prevent convective heat loss between your body and the ground. A patent-pending, multi-function low profile valve means inflation and deflation faster than any other mat, and easy fine-tuning of the comfort level. All Sea to Summit sleeping mats come with an integrated Airstream Pumpsack and a repair kit containing six self adhesive patches for repairing punctures in the field, and a spare silicone one-way valve flap.
