Optimised for warmth and comfort

Sharing a construction method patented by Exped® but with insulation optimisation technology designed and developed in-house by Mountain Equipment, our Aerostat Mats are amongst the very warmest sleeping mats available. One is filled with POLARLOFT® insulation, the warmest synthetic insulation available in wet conditions; the other with DOWN CODEX® approved duck down for the greatest thermal resistance in dry conditions. These are sleeping mats built for comfort and warmth no matter where you are.
Windsock™
After numerous prototypes and iterations we have developed the Windsock™. The best method we have yet found to inflate a sleeping mat. A design which offers rapid, easy, and reliable inflation without the need for heavy or gimmicky accessories. The Windsock™ works equally well whether in the thin air of the Himalaya or valley camping in the Alps.
Helix™ Baffle
Our patent-pending Helix™ Baffle vastly reduces down migration inside our Aerostat Down 7.0 Mat, keeping the down and subsequent warmth evenly distributed. Vertically aligned baffles plugs on both models combine to achieve the highest possible R Values for their weight.
Resistant Outer
30D ripstop nylon face fabrics and a hydrolysis-resistant protective coating to the inside of the mat balances the need for durability with the importance of low weight and packability.
Gas Mask Valve
Our Gas Mask valve is 2-way and allows a user to inflate their mat without fear of air escaping, but allows the user to dump air out quickly when it’s time to strike camp. Our custom-developed design makes identifying the correct valve parts easy.
