Sea to Summit Comfort Light Sleeping Mat [Large]

The Comfort Light 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. We use 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.

Details
• Exkin Platinum® fabric and Thermolite® insulation are combined to prevent radiant and convective heat loss
• Multi-function valve for easy inflation, deflation and fine tuning of air pressure
• 40D rip-stop nylon face fabric offers the right balance between weight and durability
• Our TPU lamination process - one used in the medical and aeronautical industries but unique to the outdoor industry - is vastly superior to the roll-to-roll lamination process that is commonly used in outdoor products at present. The TPU bonds better and more consistently, virtually eliminating delamination issues.
• Extended storage instructions: mat should be laid flat, folded as few times as possible with valve open

Technology
• Air Sprung Cells: 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'.
• Multi-Function Valves: Patent-pending, low-profile multi-function valve allows for easy, fast inflation and deflation and enables the user to precisely fine tune the firmness of the mat-tress.
• Liquid-Extruded TPU Lamination Process: An advanced lamination process which ensures an even and durable bond of the TPU (material which makes up the air bladder) to the face fabric. This process is superior to typical 'roll-to-roll' lamination and virtually eliminates the risk of delamination.
