Jacket is a Carhartt Full Swing Chore Coat. Exterior is cotton duck, with a full fleece lining, which I find to be very warm, especially with the sherpa collar. Jacket does not have any patina yet, as it is barely worn or broken in. The fit is regular, and I find it to be perfect for a medium. If you are used to standard carhartt and have not worn the full swing products, they do feel a bit less baggy, yet easy to move around and work in.
