The Prestige-Line curtains feature a special sun-reflective silver material layer, effectively reflecting sun rays and reducing heat in your truck cabin. The inner side of the curtains is made of high-quality velvet fabric in color of your choice. The windshield curtains come with hooks for rail mounting and can be connected to each other using a zipper. To attach the decorative ruffle included in the set, simply use the Velcro provided or fasten it with pins to the rubber window seal.
