Sea to Summit UltraLight Sleeping Mat - Large

The Ultralight sleeping mat range has a single layer of medium resolution Air Sprung Cells™ to give you the lightest and smallest packed-volume mat without compromising comfort. These mats are ideal when going light and fast is your aim and getting a great night's sleep is essential for the next day's adventure. All Sea to Summit sleeping mats come with a quality stuff sack, a repair kit containing six self adhesive patches for repairing punctures in the field, and a spare silicone one-way valve flap.

Details
• Multi-function valve for fast and easy inflation, deflation and fine tuning of air pressure
• 40D rip-stop nylon face fabric offers the right balance between weight and durability
• The 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.
• An anti-microbial treatment is added to the TPU to prevent issues caused by warm, moist air trapped inside the mat.

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.….
