Our sandstone Detroit jacket works as hard as the industrial city itâs named for. Constructed of tough 12-ounce, 100% cotton sandstone duck, it features warm sherpa lining in the body and quilted-nylon lining in the sleeves. Well outfitted for storage, the jacket includes a left-chest pocket with zipper closure, plus an inside pocket as well as two lower-front pockets with zipper closures. The adjustable cuffs and waist enhance fit, and a pleated bi-swing back adds comfort. Built Carhartt strong with triple-stitched main seams.
