Down Air Mat Light
Down filled Mat from Exped. Heat loss is dramatically reduced with goose down insulation. Both EMPA, the Swiss government's material test and research laboratory, and private expeditions assisted to provide tests for the Downmats. A thick cushion of air provides comfort and smooths out uneven ground. And down compresses well, so that Downmats pack smaller than other pads. A combination pump and stuff sack is included for storing and inflating the mat. Pumping air rather than blowing it prevents humidity from reaching the down, which could clump or freeze. Foam has also been added to the pump sack to assist the inflation process.
