This coat was made by Ralph Lauren under the Polo label. This one was made in the USA and probably dates to the 1980s. The style is based on a short lived variant on the work mackinaw, popular very briefly in the late 1930s, with a zip front, handwarmer pockets and flapped cargo pockets, a belted back and a zipped split hood. In keeping with the origins, this one is made with unlined construction.
