Block the sun from penetrating your Class A windshield. One size fit's almost every Class A windshield with no drilling necessary. This is a must-have product for anyone who camps in the sun. While drapes and folding windshield reflectors prevent light from entering the windshield, this product stops the heat, eliminating the greenhouse effect. Plus, it prevents dashboards and curtains from fading in the sunlight. A cheaper, easier alternative to custom-fit windshield covers that will not leave your coach full of drilled holes. Constructed using patented Tyvek® RV™ fabric by DuPont™. Patent pending design secures in minutes with no need for drilling. Quick-connect buckles attach at 3 contact points: mirrors (bottom & top mounted models) and any accessory on the RV roof. Decreases need for A/C usage while camping. Includes storage bag. 2 year warranty.
