Mountain Equipment Aerostat Down 7.0 Sleeping Mat Wide Regular (R5.0)

The Aerostat Down 7.0 Mat Wide Regular is a down-filled sleeping mat built for those who refuse to compromise on warmth or comfort in the backcountry. With 205 g of 700 fill power duck down distributed through vertically aligned baffles and Helix technology to prevent migration, it delivers consistent insulation across the full surface of the mat. At 7.0 cm thick and with an R Value of 5.0, it is well suited to cold conditions and extended expeditions where a good night's sleep is non-negotiable.

The recycled 30D ripstop polyester shell with TPU lamination keeps weight and pack size low, while the 2-way self-sealing Gas Mask valve makes inflation and deflation straightforward. The included Windsock inflates the mat quickly and doubles as a lightweight stuff sack, and a repair kit is also supplied.
