The Innershirt is made for cold days with a lot of wind. On the front of the Innershirt there is a layer that blocks the wind and keeps your upper body protected from the cold wind. The wind stop is on the entire front and slightly out on the shoulder so that it covers the most exposed places.

The Innershirt works really well in the fall, when the temperature is reasonable, but the air is the biggest cooling factor.

The rest of the sweater is made of a slightly thicker sweat-transporting material, so you get rid of the sweat from the body, and the sweater still insulates and keeps you warm.
