This vintage coat is a “Mighty Mac” Boatcoat. It is a peacoat style with a twist. With its navy blue Melton wool body, its handwarmer pockets, patch pockets and button-on hood, it draws from the designs of WWI peacoats, WWII peacoats and British duffel coats to create something which is unique, yet recognizable. These were marketed in the late 1950s through to about 1962 by Mighty Mac to the high school and college aged crowd, and were made in sizes 14 through 20 (ages). This one is the largest size, a young man’s 20, which is equivalent to a men’s 40. It originally sold for $37.95, which is roughly equivalent to $300 in today’s money.

Chest (pit to pit): 23″ (doubled = 46″)
