Oakley SI Polarized Flak Jacket Sunglasses
Oakley SI Polarized Flak Jacket Sunglasses are designed and engineered to be standard issue (SI) for world-class athletes and technicians.
Lightweight, rugged O Matter frame material resists stress and maximizes comfort for all-day wear, while the frames meet ANSI Z87.1 standards for high-mass and high-velocity impact. Hydrophilic Unobtainium material at the stem sleeves and interchangeable nose pads provides a secure, comfortable fit, even when it's raining or you're sweating. The semi-rimless design means there's nothing to block your downward view. The comfort and performance of Oakley's Three-Point Fit holds lenses in precise optical alignment for superior clarity.
Oakley HDPolarized lenses are engineered to filter out 99% of reflected glare without the haze and distortion found with ordinary polarized lenses. Plutonite lens material blocks 100% of all UV rays and harmful blue light up to 400 nm. Incorporating Oakley's High Definition Optics (HDO) and XYZ Optics technologies, Flak Jacket sunglasses extend razor-sharp clarity at all angles of view, maximizing peripheral vision and protection against sun, wind, and side impact. Flak Jacket lenses meet ANSI Z87.1 standards for optical precision and performance.
Hydrophobic permanent lens coating prevents rain and sweat from building up on the lens, as well as eliminating static electricity, so dirt and dust particles won't cling. Oleophobic lens coating repels skin oils and other contaminants, leaving the lens smudge-resistant and easy to keep clean. Quick, tool-free lens changing lets you optimize your vision in any sport environment. Includes a Sport Soft Vault Case and extra nose pads.
