Stayfast Soft Tops
Many People ask, "What is Stayfast?"
Stayfast is constructed by bonding 3 layers of material together together about 25-30 mil thick. The outer layer (face) is a fade resistant acrylic fabric, the middle layer is a rubber membrane, and a final inner layer of cotton bowdrill. The lining material is plain. Overall life of the material is dependent on care given as well as sun exposure. But, overall it performs much better then Vinyl.
