The tapered shape of Air Impact self-inflating mats provides space at the upper body where it is needed but saves weight by reducing width at the legs where it’s less crucial. Weight and packed size are also saved by the lightweight ripstop nylon outer and diamond profile to the core running through the foam fill. This makes the range particularly appealing to self-propelled adventurers like trekkers, cycle tourers and kayakers. The Air Impact uses the Pump Sack compatible and flat, unobtrusive Peak Valve for ease of inflation and deflation.
