Oakley Fast Jacket Transitions SOLFX (Asian Fit) Sunglasses - 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. Between sunrise and sunset, there s a whole spectrum of possibility, but you can t take advantage of it unless your vision can adapt. If the sun pulls a disappearing act or busts its way through the clouds, just swap out the lenses with a different set. The advantages don t stop there. Pro athletes know it takes the right combination of light filtering, glare blocking, visual contrast and color balance to help them perform at their best, and it varies from sport to sport and place to place. With Fast Jacket , they have the power to adapt their vision quickly and give themselves every possible advantage.

Impact protection meets ANSI Z87.1 standards while clarity and optical precision exceed them. We achieve it all with the unrivaled technologies of High Definition Optics (HDO ), including patented XYZ OPTICS that maintains clarity at every angle of view. We use the most optically pure lens material in the industry, Plutonite . It has the added advantage of filtering out every baking ray of ultraviolet light including UVA, UVB, UVC and harmful blue light up to 400nm. Fast Jacket has open-edge lens architecture to give you an advantage when looking through the downward view. We made the frame out of comfortably lightweight O Matter , a durable material that withstands the punishment of pro sports. Each frame comes with two sizes of interchangeable nosepads to help you get a precise fit. Like the earstem sleeves, they are made of Oakley Unobtainium that increases grip when you perspire. A Three-Point Fit keeps the optics precisely aligned while maximizing comfort by eliminating the pressure points that come with ordinary frames that hook your ears.
