Engineered For high warmth in severely cold conditions, anyone who works outside can appreciate the cold-weather chops of this men's flannel-lined hooded jacket. It's crafted with rugged cotton duck, and the body and hood are lined with quilted flannel for under-the-covers warmth. A rib-knit waist and cuffs keep heat in, cold out, and prevent excess material from getting in the way of your work.
