After using cardboard cutouts for my front windows, it was time to get some premade reflective sun shades for the Toyota Prius.
Here is a link to buy them on Amazon, they are less than $20 for the front two windows.
I will say, over time with heavy daily use the material lost its strength and eventually became unusable. Granted, I wasn’t gentle with them and didn’t have a place to store them where they wouldn’t receive a lot of impact and just bags on top of them. Maybe if I had a hanging net on the roof that I always gently rolled them and stored them they would’ve lasted longer.
These custom fit sun shades fit perfectly and are easy to use.
