The Exped DownMat 7 cm Pump M is super comfortable, very warm and more compact thanks to the down filling. The thick cushion of air also provides comfort and smooths out uneven ground. And as down compresses extremely well, Downmats pack smaller than other insulated mats of the same warmth. The integrated pump makes inflation easy.
700 fill goose down is placed in cells similar to down sleeping bags. Foam baffles prevent down from escaping through the valves and migrating from one chamber to the next. Exped only uses IDFL-certified goose down, specially treated to eliminate the effects of humidity that may reach the mat's interior.
Light foam blocks at the mat's ends prevent down from escaping or migrating between chambers. Laminated polyester fabric is both durable and airtight. Top surface of honeycomb textured fabric provides superior slip resistance and comfort next to the skin. Seams are all high-frequency welded (most secure method of fusing fabrics and materials) to ensure mat integrity. Dark colors dry quickly.
Both low profile valves one for inflation and the other for deflation ensure ease of use. As the valves are flat and not on the mat‘s edge they do not protrude and are therefore protected and durable. Two loops at head end can be used to secure the packsack to the mat when used as a pillow.
Light and warm: The DownMat 7 Pump has a R-Value of 5.9 At about the same weight a standard 2.5 cm self inflating mat only has a R-Value of 2.5 Further EMPA tests demonstrated that regular mats lose 3x more heat to cold ground than to the air. The conclusion: use a lighter weight sleeping bag with a DownMat to achieve consistent overall comfort, and still reduce weight and bulk!
