This vintage coat was made in the 1930s. It is a single breasted mackinaw, with handwarmer pockets and flapped cargo pockets. It has a convertible roll collar. This style was generally called a “stag coat” at the time. It has an interior wind flap and a double thick front. At some point,it was re-lined with a heavy cotton lining, but it would have originally been made un-lined.
