Short and sweet. I've looked high and low, local and all over the Internet for this item.  Amazon has the best price, and when I got this jersey jacket, it is EXACTLY what I wanted.  All other versions imitate this benchmark top-of-the-line jacket from Carhartt. It is very warm, and the zipper is heavy duty brass that is durable and high quality like I've wanted ever since having to throw away cheaper versions with plastic zippers that before long quit working or start loosing teeth.  Man I'm glad I found this.  I'm not kidding.
