Refining lightweight cold-climate sleeping comfort, this mat combines a lightweight 30/40D Nylon fabric, Exkin Platinum and THERMOLITE insulation with a loop baffle Air Sprung Cell construction to create a 10cm thick mat with an incredibly low weight. Larger air pockets are created by using many looped TPU baffles which connect the top and bottom fabric layers with our Air Sprung Cell dot weld pattern. The looped baffles allow the top and bottom layers to be positioned further apart creating larger pockets of air when inflated that require less fabric overall. Perfect for side sleepers, the extra height of this mat lets hips sink deeper into it without touching the ground. Includes an Airstream Pump that is integrated into the stuff sack for quick and easy inflation Extra Thick (XT) loop baffle Air Sprung Cells - Air Sprung Cells are the core technology of our sleeping mat range, and are the reason why you will sleep better on a Sea to Summit sleeping mat. Instead of the typical baffled construction, Sea to Summit sleeping mats are constructed using a dot-weld pattern to create a high surface-area matrix of interconnected chambers called Air Sprung Cells. Air Sprung Cells operate in the same way as a pocket spring mattress. As each cell deforms independently the mattress conforms to your body shape. This makes for a softer and more comfortable feel with more body contact area and even dispersion of pressure. Lightweight, quiet and grippy 30/40D Nylon fabric, field repairable with included self-adhesive patches Ultra-Fresh anti-microbial treatment to the TPU formula to prevent internal mould growth PillowL
