Universal fit for 99% of vehicles: Each shade is designed to fit a specific vehicle model, ensuring a precise fit. Sizes are measured manually, so please measure your windscreen before to select the size. Advanced sun shade material: Made with nano ice crystal material to significantly block UV, IR, and heat. The silver reflective cover helps reflect ultraviolet rays, while the black side provides heat isolation to keep the cabin cooler and slow interior aging. Effective darkness inside: When installed, the shade creates a noticeably dim interior by blocking the vast majority of UV rays, protecting occupants from sun exposure and UV damage. Protects and preserves your interior: Insulates the cabin from temperatures, helping maintain a stable interior climate. By reducing sun exposure, it helps prevent aging of seats, dash, and other components, reducing fading, cracking, and warping. Use scenarios: Parking outdoors for extended periods in direct sun: lowers interior heat and blocks UV to protect upholstery and panels. Daily driving in bright, hot climates: reduces heat buildup and UV exposure for a cooler, more comfortable cabin. Long road trips or transporting children and pets: provides ongoing interior protection and a more pleasant environment.
