Back in the day, aviators had flat lenses and simple barrel hinges, but thanks to the Oakley Plantiff Sunglasses, those days are long gone. Now lightweight alloy frames rock burly leaf-spring style hinges that let the Plantiff's arms flex past the point of no return to easily slide on your face. Curved optics not only maximize peripheral vision but also add dimensional style, and do so without gnarly distortion. We could go on and on, and eventually say something about afterburners and 4G inverted dives, but that's probably unnecessary. Plutonite lenses use a 8. 75 base curvature, meaning that the curve of these lenses maximizes coverage without distortionC5 metal alloy frames are strong, lightweight, and flexible in order to put up with life in the danger zoneMono Shock hinges borrow race engineering that uses leaf springs to allow the stems to flex beyond the limit of normal hingesA UV lens coating filters out 100% of UVA/UVB/UVC and blue light up to 400nm so the suns damaging rays won't degrade your visionOakley lenses meet all ANSI Z80. 3 standards of shatter- and impact-resistance
