The Filson and Mossy Oak® Mens Mackinaw Wool Field Jacket is like no other. This cold weather hunting jacket continues to insulate even if it becomes waterlogged. This makes it the perfect outer layer for hunting in cold, wet weather. Made of Filson's wind and water resistant 24.oz. Mackinaw Wool and cotton. It was designed with a roomy fit that allows you to smoothly shoulder a gun or draw a bow. Mossy Oak®’s original Bottomland® camouflage pattern from 1986 is woven into the coat to preserve the pattern’s integrity and the fabric’s performance.
