One hard-working garment, our Carhartt RNJ001 Weathered Duck Detroit Jacket is made of 12-ounce, naturally worn, 100% ring-spun cotton duck that has been washed for a naturally worn, already broken-in-feel. It features a blanket lining in the body and quilted nylon lining in the sleeves. There’s a corduroy top collar with under-collar snaps to attach an optional hood. Inside, there’s a welt pocket and 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.
