A functional sun shade for rear door windows. It covers the window pane and effectively protects rear seat passengers, such as a child in a rearfacing child seat, from heat and irritating sunlight. The sun shade also gives the car the stylish "look" of tinted windows. If the rear side windows need to be lowered during a journey the sun screens minimize the wind noise, aka "booming noise", that can arise. Two clips are fastened in the doors' cover panel after drilling. Installation aids included. Supplied in pairs in a formfitting storage pouch one sun shade per side. The sun shade cannot be folded.
