Our Detroit jacket is a classic. It features rugged, 12-ounce, 100% cotton sandstone duck as well as quilted nylon sleeves and sherpa lining in the body and pockets for warmth. The princess back seams and built-in bi-swing are designed to give women a premium fit while the adjustable waist and wrists provide added comfort. We’ve also built in a chest pocket with a zipper closure for secure storage. *Sherpa-lined *Triple-stitched main seams *Princess back seams
