This car sun visor is your thoughtful guardian for summer driving. It adopts multi-layer composite materials, with an outer layer of highly reflective aluminum foil that can effectively block 99% of ultraviolet rays and strong light, and an inner layer of insulation cotton that can reduce the temperature inside the car, so that you no longer face the "steaming hot" feeling when opening the car door. The size of the sun visor has been accurately calculated and is suitable for the vast majority of sedans and SUVs on the market. No tools are required for installation, just fix it on the front and rear windshields, and the elastic band design ensures that it will not slip off during driving. In addition, it also adopts a folding storage design, which can be easily folded into palm sized pieces when not in use and stuffed into the door storage compartment or trunk, without occupying extra space. Whether it's scorching summer parking and sun exposure, or dealing with glaring sunlight during long-distance driving, this sun visor can provide you with a comfortable interior environment while protecting the dashboard, seats, and other interior from UV aging damage, making it a practical choice for every car owner.
