Have you ever felt really hot in a car on a sunny day? Well, that's because the sun is shining down on your car and making it super hot! A windshield sun shade is like an umbrella for your car. You know how an umbrella keeps you shaded from the sun when you are outside? Well, a windshield sun shade does the same thing for your car! It's like a big piece of fabric that you put up in your car's windshield to block out the sun. This way, your car doesn't get too hot and it's more comfortable to ride in when it's sunny outside. Plus, it protects the inside of your car from fading and damage caused by the sun's rays. So, if you're going on a road trip or just driving on a hot day, be sure to bring along your windshield sun shade to keep your car nice and cool!
