Brightness is a nuisance to their eyes (especially if car rides equal naptime), and car windows don?t provide adequate protection against UVA rays - so it?s good sense to practice sun safety while you drive.

And with a patented White Hot? system that turns white when it's too hot in the car, so you can have peace of mind that baby is safe and comfortable.
