Robens says about the Air Impact 38
The Air Impact self-inflating mats are designed with a tapered shape, providing extra space for the upper body while saving weight by reducing width at the legs where its less needed. The lightweight ripstop nylon exterior and diamond-profile core reduce weight and pack size, making this mat ideal for adventurers with limited space, such as trekkers, cycle tourers, and kayakers. The Air Impact also features the flat, low-profile Peak Valve, compatible with a Pump Sack, for easy and efficient inflation and deflation.
