The "Coat, Mackinaw, OD", also called the "Jeep Coat" was first issued in 1938 (called the "first pattern"), intended for cold weather use by troops who did not engage in much movements, such as drivers. The Mackinaw had a water resistant cotton duck outer shell with a wool blanket lining. The distinguishing feature of the first pattern mackinaw was that the 30 oz. blanket lining extended visibly over the shawl collar.
