Construction workers have enough things to worry about than suffering through a day wet and cold. The CornerStone Men's Duck Brown Duck Cloth Work Jacket possesses 100% cotton duck, which weave tightly throughout the jacket to keep the warm air in and the cold air out. Soft to the touch, this workwear jacket is much more wind and water-resistant than standard construction clothing. Polyfill nylon lines the inside of the construction jacket to enhance insulation. As a workwear staple, the CornerStone Duck Cloth Work Jacket makes the perfect outer garment for layering clothes. Triple-needle stitching at the shoulders and armhole ensures long lasting durability.
