This is an Oakley AIR BRAKE. Used about 3 times and I'm selling it because I won't be using it this year. The lenses are Prism Blue Iridium and Red Iridium. It's a set of 4 lenses, the original two types, suitable for all weather conditions, I believe. Comes with the case and the original instruction manual. It's in beautiful condition. Please comment if you have any questions about the price.
