The WeatherTech TechShade is a custom fit windshield and window sun shade that protects your vehicle's interior from harmful UV rays. These are custom fit sun shades that will keep your vehicle cool in the summer by reflecting suns rays. In the winter use the black side to absorb the suns rays and help prevent frost from forming. Custom fit and perfect for any season, the TechShade can keep your vehicle cool in the summer and help prevent frost build-up in the winter. Reflective film chases the sun away in summer. Then, the reverse side absorbs the heat for those cold winter months. When not in use, the TechShade is easily removed, rolled and secured with a Hook & Loop strap. The WeatherTech TechShade is available in full vehicle kits depending on your make and model. WeatherTech TechShade Full Vehicle Kits help keep your entire vehicle's interior temperatures down while protecting it from the sun's damaging effects. TechShade Full Vehicle Kits include 4 or 6 pieces depending on the vehicle model.
