Down trekking mattress -
The Aerostat Down 7.0 Mat is a 4-season mattress from the brand Mountain Equipment.
This 4-season mattress allows you to camp all year round. It stands out for its excellent thermal insulation in down. Indeed, with a R-Value of 5 achieved thanks to a duck down lining, it withstands the coldest nights. In addition to being highly insulating, this mattress has a low weight of 740 g: no problem carrying it with you on all your high-altitude treks. Its materials offer one of the most efficient weight/resistance ratios, allowing you to camp on uneven ground without fear of puncturing your mattress.
The Gas Mask bidirectional valve lets you inflate your mattress without air escaping, and deflate it without accidentally reinflating it. Convenient for breaking camp quickly and easily! This mattress also comes with its Windsock™, a small tube to inflate the mattress quickly and without introducing moisture. The repair kit is also included. The icing on the cake: this model meets the ASTM F3340 standard thanks to its excellent thermal performance.
For a good night’s sleep during your treks in cold temperatures, choose the Aerostat Down 7.0 Mat.
