The Oakley Fast Jacket sports sunglasses use Switchlock technology for quick and easy lens changing via a slick metal lever. Think of Switchlock as a quick release for your lenses. Just flip the lever and the lens pops out instantly with no strain or need to "muscle" the lens. The Fast Jacket is technically a sport sunglass but has the style and not too big size that makes is perfect for casual wear also.
Fast jackets suspend the lenses 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. Just put in a new lens set and go. So even if condition change, you can always have the best lens option.
Included with the Fast Jackets (polished black frame) are Black Iridium and Persimmon XL lenses. The XL lenses provide a little more coverage on the bottom outside corners for cycling (the Fast Jacket frame is the same for both standard and XL lenses). The Black Iridium lens is an excellent all-purpose lens for sunny conditions. It offers truer color perception and features an Iridium® coating to reduce glare. Persimmon is perfect for flat to low light.
Oakley engineered Fast Jacket® to be so lightweight, you'll forget you have it on. Unlike ordinary frames that hook the ears, Fast Jacket offers the comfort of a Three-Point Fit with balanced pressure points.
Oakley lenses have exceptional clarity and contain features not found in other lenses. Hydrophobic HDO® lenses make lenses much easier to clean versus other lenses. Also, the anti-static coating won't attract dirt like regular lenses. High Definition Optics® (HDO) take advantage of patented innovations, like XYZ Optics® for unbeatable clarity at all angles of vision--even at the sides of lens contours that open peripheral view and optimize protection against sun, wind and side impact.
