Perfect for Children! Young kids in back seats are most vulnerable to heat and strong sunlight. Installing these shades on rear car doors provides shade for car/booster seats, offering UV protection, reducing glare, lowering temperatures, and preventing sunburn or overheating for your little ones. Super Easy Installation! Simply pull down this soft, stretchy shade to cover the open door. Fits most vehicles with a max length of 126 cm / 49 inches and max height of 50 cm / 20 inches. Keep Your Windows Down! The breathable mesh installs outside the window frame, letting you open windows for cool breezes while staying shaded from the sun – something tinted films can't do! Upgraded Design! No adhesive tape needed on your windows. Removes cleanly with no sticky residue left behind. Fits Most Vehicles (Rear Windows Only)! Compatible with common car types: large vehicles with tempered glass, small doors (curved/rectangular windows), MPVs, hatchbacks, small SUVs, and large SUVs/crossovers (curved/rectangular windows). Fits windows up to 45 inches wide.
