Great replacement for a coat
I don’t like wearing a coat in Wisconsin. I wanted a solution that provided warmth while still fitting my aesthetic. This base layer 4.0 has been perfect for me. It’s fitted, not bulky and makes a huge difference in keeping my chest and arms warm with just a long sleeve on top of it. I recommend!

SO WARM!
This shirt blew my expectations away. I wear this on patrol and it keeps me warm throughout the night. I usually wear size L but got a M and it is nice and snug.
