Mountain Equipment Aerostat Synthetic Mat

With an R-value of 4.0, this mat is designed for three-season use. It provides enough insulation to keep you warm during chilly spring and autumn nights, though it may not be sufficient for extreme winter conditions.

The Windsock is a lightweight bag that attaches to the mat's valve. You fill the bag with air by waving it open, then roll the end to push that air into the mat, which is much faster and less moisture-intensive than blowing it up by mouth.

Yes, the vertical baffles are designed to provide a more stable surface than horizontal ones, which can sometimes feel like you are rolling off the sides. They create a consistent, supportive feel that helps keep you centered on the mat throughout the night.

The mat is constructed from 30D ripstop polyester, which is quite durable for backpacking gear. While it is tough enough for most tent floors and flat, cleared ground, you should still avoid sharp rocks or thorns to prevent punctures.

The Aerostat Synthetic 9.0 comes with an included repair kit. It is a good practice to keep this kit in your pack at all times so you can quickly patch small leaks or tears while you are out on the trail.
