Duck Insulated Coverall is made from a tough 12 ounce weight cotton fabric to withstand tough use. Being one of the best insulated coveralls it features water repellent and firm hand brown material that provides warmth and safety in cold work environments. The oversized pockets and quality brass zippers are made with heavy duty material for durability regardless on the work you do. You can easily remove or put on your boots with the side zipper and button on the legs. It is always a good a idea to get one size bigger to offset future washing shrinkage.
