What a great cold weather coat!  I used to layer up with a couple of sweatshirts under my military field jacket to stay warm, but since I bought this coat I've been out in single digit temperatures with only a T-shirt on under it and stayed warm and comfortable.  A bit on the heavy and bulky side, but if you want to stay warm this is the cold weather coat you want.  Rugged Carhartt quality is a big plus!
