Our warmest fabric, waterproof insulated jacket is designed for end-of-season hunting where you can sit on exposed glass spots or ride through howling winds and snow. Synthetic insulation with 3M technology replicates the performance of down insulation, but with warm properties when wet. It maximizes temperature while minimizing volume and increasing maneuverability.
The unique structure of the fabric is made of two different substances. One is that the e-PTFE film is waterproof. There are 9 billion tiny pores in a square inch of film. And a drop of water is 20,000 times larger than these tiny pores, and water can't pass through them. In stormy weather (snow) can still resist the entry of rain (snow), to be 100% absolute and then each micropore is 700 times larger than the human body sweat molecules, sweat can easily pass through the fabric.
