Top is made from a non-original durable cloth topping material and includes all factory attachment, retainers and connectors for a quick and accurate installation. ABOUT THE MATERIAL: Manufactured using premium Haartz Stayfast canvas, which is mold and mildew resistance and has superior resistance to long term exposure to the sun. It's an three-ply composite made of acrylic square weave outer fabric, a rubber inner layer, and a cotton lining fabric. Includes a new heated glass window. The window is bonded using an advanced window bonding system with a clean, finished "OEM" look. The added strength of this bonding method keeps it from leaking or separating during normal use.
