The Bestop Replace-a-Top includes no hardware and is designed to be used with the Factory hardware only. Matte Black Twill fabric is the same fabric used in all sorts of expensive sports cars and European luxury cars. Instead of the normal Jeep vinyl, this fabric is much more luxurious feeling, much more cloth-like. it is also the heaviest fabric Bestop has ever used, so it is not only a lot quieter, it is going to help stop heat transfer as well. The fabric is actually three heavy layers: Twill on the outside, rubber waterproofing, and finished twill on the inside. It makes the inside of the top look as finished as the outside. Since the fabric is the best ever, Bestop also upgraded and added extra thick 40mil windows and a Limited Lifetime Warranty.
