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 and will fit your coach like a glove. Quick-connect buckles attach at 3 contact points - mirrors (bottom and top mounted models) and any accessory on the RV roof. Decreases need for A/C usage while camping. Includes storage bag.
