There are a number of different materials used by Carhartt for their articles of clothing, constructed from very durable outer fabrics . This includes cotton canvas (lightweight 9-ounce, 100% cotton canvas), cotton duck (heavy-weight, 12-ounce, 100% cotton duck) and 8-ounce, 100% cotton white drill. Due to their expert construction and the material used, Carhartt jackets are said to have lifelong durability, such as the J133 Carhartt Men’s Extremes Active Jac with Artic-Quilt lining – that has a warm insulation lining, is water-repellent, blocks wind, has ribbed cuffs and an attached hood.
