Benefits Blocks harmful UV rays to protect passengers, especially young children, from sun exposure and heat. Reflects up to 99% of the sun’s rays to reduce interior temperature and keep the cabin cooler. Mounts without restricting window movement so you can enjoy fresh air while the shade remains in place. Key features Direct-attach design fastens to the vehicle body/window area while allowing free window operation. Includes two suction cups that secure the shade to the glass for quick installation and easy removal. Suitable for use on both front and rear car windows to provide consistent protection throughout the vehicle. Function and performance Sun protection: blocks UV radiation and reduces solar heat gain to help protect skin and interior surfaces. Temperature control: reflective surface helps lower cabin temperature, improving comfort on sunny days. Practical use: stays attached during normal driving yet allows ventilation because it does not prevent the window from moving. Compatibility and materials Designed for use on car front and rear windows; installs without modifying the vehicle. Constructed from sun-resistant shade material and reinforced where it mounts for reliable everyday use. Typical use scenarios Family trips: shields children in rear seats from direct sunlight during long drives. Parked vehicle: reduces interior heat buildup while you run errands or wait with passengers aboard. Driving with fresh air: let in outside airflow by lowering or raising windows while the shade continues to block direct sun. Installation and care Attach the shade to the window pane or body area and secure with the two supplied suction cups. Remove easily when not needed; store compactly until next use. This car sun shade provides straightforward UV protection, temperature reduction, and the flexibility to keep windows operational for ventilation.
