The Enovoe Car Window Shade is made of mesh fabric and blocks over 97-percent of harmful UV rays. The shade provides protection from heat and sun glare, keeps your car cooler, and reduces skin irritation. The dual-layer design provides excellent protection without compromising the driver’s ability to see and drive safely. Rather than using suction cups, the shades use static to stick to the windows, making them easy to place and remove as required. The shades come in a pack of four and measure 21 inches by 14 inches, making them ideal for windows on larger cars, minivans, and SUVs.
