Early this year, Jeep launched the new 2013 models. All these models come with a new premium soft top which are made of Haartz’s Twillfast RPC. It is an acoustically enhanced three-ply composite made of acrylic twill weave outer fabric, a rubber inner layer and polyester lining fabric.
The soft tops are definitely cheaper than the retractable hardtop designs. However, the problems with soft tops is that they were not really good at noise insulation and are quite difficult to clean. Haartz’s soft top overcomes these by including a rubber inner layer which provides enhanced acoustics. Furthermore, the Twillfast RPC is easier to clean than previous materials used for the soft top Jeep models.
