This is one hard-working garment. Carhartt's duck Detroit jacket is made from rugged 12-ounce, 100% cotton duck, and features a blanket lining in the body with quilted nylon lining in the sleeves. There's a corduroy top collar with under- collar snaps to attach an optional hood. Inside, there is a welt pocket and on the outside there are two large front pockets and a zippered left-chest pocket. The waist and cuffs are snap adjustable, and the bi-swing back makes for easier movement.
