This vintage mackinaw coat was made in the 1920s. It is tailored from red and black Hudson’s Bay Company point blankets, in a classic double breasted cut. The coat is belted, with flapped hip pockets and slash handwarmers on the chest. The belt has buttons instead of a buckle, a typically 1920s detail. As with most mackinaws of this era, this example is unlined, with finished interior seams. This blanket material was highly sought after in this era for serious outdoorsmen. Upgrading to point blanket material over standard mackinaw wool could almost double the price.
