This Mercedes convertible top is made as original using patterns and specifications to the original vehicle. This includes German Classic canvas from Haartz Germany, which is a premium quality topping with 100% polyester dobby weave lining fabric. German Classic is the original material used by Mercedes. It is an acoustically enhanced three-ply composite made of a polyester/acrylic twill weave outer fabric, a rubber inner layer and a cotton lining fabric. This is the most durable of the two fabric choices and has a slightly silkier feel, richer color and appearance.
