The Carhartt’s tough outer shell is constructed of 12 ounce, 100% cotton sandstone duck material. It’s tough and tear-resistant, tightly-woven and durable against wind. In the body of the insulated Carhartt jacket, quilted flannel lining holds in your natural warmth to provide comfort in cold conditions. The sleeves are finished with rib-knit cuffs that create a snug seal around each wrist, blocking cold air. The waistband has been rib-knit as well, a construction method that also prevents fraying. The hood is attached, and adjustable with a draw-cord closure. Even the hood on this insulated Carhartt jacket is lined with quilted flannel to extend the warmth all the way up to your head. Two inside pockets and two lower front pockets.
