When you are driving around in your car and singing along to your favorite song of the summer, you are wearing your Ditty Sunglasses by VonZipper. The lightweight frames lie so comfortable on your face that you forget you are wearing sunglasses until you show off a new dance move that sends them flying into the seat next to you. Thankfully the impact-resistant lenses are dance-proof so you can continue to enjoy the song.
