IME there aren't any. If your doing it for kids in the back seat just tint your windows
I want to get car window shades. What's the best one to get?
https://www.amazon.com/Window-Protection-Shades-Stretchy-Through/dp/B06WWQ7CP6These look great and cover the whole window. Plus act as a screen and can open window while it's on.
Does it look weird from outside the car?
