Now side windows won't let heat, UV rays and glare in to make your child hot and uncomfortable. Our patented White Hot® heat alert will let you know if the car's temperature is unsafe for your child. The retractable shade opens and closes with a 2-step release button, and is easy to adjust to any window. It stays securely on your window with suction cups and has a suction cup pull-handle. It makes everyone a little more comfortable in the car.
