A Clean Run exclusive! The Universal Sun Shade is a heavy-duty, flexible, and highly reflective cover that easily attaches to the outside windows of your vehicle, adding shade and keeping the inside cooler. It's made out of mylar-coated vinyl. Attach the Sun Shade to your back window, side window, or front windshield; six built-in suction cups secure it in place. Because the Sun Shade goes on the outside of the vehicle, you can easily move it to different windows as the sun moves. The Universal Sun Shade rolls or folds up for easy storage in the vehicle. Size is 54" at the top flaring to 60" at the bottom. Each side of the shade is 29".
