Aochol Car Seat Temperature Baby,Sun Protection Material Cover for Keep Your Baby's car seat at a Lower Temperature,Auto Window Sun Protection with Carseat Shade Reflector UV Ray Helpers(Sliver)

While this does keep a car seat from getting hot in the sun, it really is not easy to use. There is not elastic so you just have to pull over, it is a drawstring with elastic that you have to maneuver all around the seat to secure. It takes a bit of time and is not at all convenient. I had to purchase another model, this was a waste of money.

They have a draw string but difficult to cinch the string for snug fit

It does keep the carseat cooler so my son doesn’t burn when sitting on it

Works great!! Keeps seat cool.
