Lightly used Oakley Fast Jacket Sunglasses. Black Frame. Have had these for 1 year - but got Smith Optics as a gift - so these need to go. These are as good as anything I've worn. Retail for $220 - but I misplaced the case and cleaning cloth - no extra lenses - but easy to change to new color. Lenses are in very good condition. Non-noticeable light swirls on lenses but want to disclose. Cannot be seen while you are looking through these polarized lenses. Great gripping for sports type activities - also cool while playing bass! From Oakley site: >> We took the idea of “adapt and conquer” to the extreme. Oakley Fast Jacket™ is a performance product with a unique interchangeable lens design that lets you match your optics to your environment. Switching out the lenses is fast and easy, thanks to Switchlock™ Technology. It’s an innovation that locks the lenses in place with a quick release system. With Switchlock, the lenses are securely suspended without any stresses that could alter the optics, so you’ll have premium clarity with true, accurate vision. We shaped stainless steel with metal injection molding to create a convenient button that releases each lens. That means minimal handling and no hassle. Just put in a new lens set and go.<< Ships USPS Priority. No trades please. PPal only.
