Our Carhartt Seat Covers are made from the same iconic duck-weave fabric you have come to love in the clothing. Made from the strongest cotton and is there most durable canvas. This fabric is crafted with added toughness and water repellency to hold up to the toughest abrasions and spills. Carhartt Brown Duck was initially created by Hamilton Carhartt for railroad worker overalls back in 1915 which revolutionized the clothing for the working class that needed clothing to hold up extreme abuse in any weather. This duck fabric has continued to evolve over the years though the initial duck fabric is still in use. We use the Firm Duck fabric in our seat covers to provide the rugged protection, comfort, and style you need in your seats.
