What is more American than fast cars and star spangled banner sunglasses? We have been a big fan of Knockaround sunglasses for years now, and its what we wear at every track event. Don't let the price fool you, these high quality sunglasses pack a punch. The blue fonts with the red, white and blue arms will tell everyone that America is #1, even if your car is German.. :). These glasses come with Polarized Lenses.
