Oakley Fast Jacket™ is a performance product with a unique interchangeable lens design that lets you match your optics to your environment. They took the idea of "adapt and conquer" to the extreme with these glasses. 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. Oakley shaped stainless steel with metal injection molding to create a convenient button that releases each lens. That means minimal handling and no hassle.

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. With Fast Jacket™, you have the power to adapt your vision quickly and give yoruself every possible advantage.

Oakley Fast Jacket™ comes with the unbeatable technologies you expect from a world leader in performance innovation. Impact protection meets ANSI Z87.1 standards while clarity and optical precision exceed them. Oakley achieves it all with the unrivaled technologies of High Definition Optics® (HDO®), including patented XYZ Optics® that maintains clarity at every angle of view. 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. Oakley 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.

Oakley Fast Jacket™ comes with two sets of interchangeable lenses. We formulated one set for bright sun and engineered the other for lower light, so you'll be ready for a wide range of environments. It all stows conveniently in the included case. When you're ready to hone-in on the best optics for your particular sport or application, take a look at the optional lens sets made for this premium performance sunglass.
