2. Block sun, insulate heat and protect interior: Made of sun-shielding material, it can block part of the direct strong sunlight, reduce the exposure of the car seats and instrument panel to the sun, slow down the aging of the interior, and at the same time lower the temperature inside the car in summer.

3. Block dust and debris: When driving or parking, it can prevent dust, fallen leaves, flying insects and other debris from entering the car when the windows are slightly open, keeping the interior clean and reducing the frequency of interior cleaning.

4. Improve driving safety: It can reduce fog on the window glass caused by temperature difference on rainy days, improving window clarity. At the same time, it prevents the driver from being distracted by rain when opening the window, indirectly ensuring driving safety.
