Shade Styx is a manually operated universal rear window sunshade that fits over 90% of the passenger cars on the market today. With the same ultra- premium quality sun protection found in luxury cars like Mercedes, BMW, Lexus and Audi. Shade Styx adds value by adding comfort to rear seat occupants and for protecting your interior from damaging sun. It's easy to install by affixing to the built-in car-seat anchors in your rear window deck. Installation takes about 5 to 10 minutes with no tools required. Shade Styx is a much more effective product to use than other shade products using suction cups that easily come undone. It's just as easy to uninstall so you can take Shade Styx from car to car. When raised, rear window coverage reaches up to 70% of direct sunlight and UV radiation being screened while still maintaining good driver visibility. Shade Styx comes with 1 year limited manufacturer's warranty.
