Protect your eyes from sunlight's shrapnel with Oakley's Flak Jacket XLJ and its longer lens design. Oakley polarized lenses were awarded the highest ranking in an independent study, beating all the competition. It's no wonder Oakley's technology is chosen by those whose lives depend on their gear, including members of the Navy SEALs. To meet their uncompromising standards, Oakley achieved unrivaled optical performance by bonding the polarizing filter at the molecular level so there is no visual haze and no optical distortion like conventional polarized lenses. Made with adhesives and thermal shaping. The Flak Jacket XLJ sunglasses feature an open-edge design of lightweight O Matter™ frame material. Offer an unobstructed field of downward view. Especially well suited for athletes and sport professionals. Plutonite®, Oakley's proprietary polycarbonate lens material, inherently blocks 100% of all UVA, UVB, UVC and harmful blue light. Durable, lightweight Pultonite provides startling optical clarity with Oakley's High-Definition Optics and protection against high-mass and high-velocity impact, exceeding the ANSI Z87.1 performance requirements of the American National Standards Institute. Oakley's fishing-specific eyewear options enhance contrast and depth perception for superior underwater viewing. For rivers, shallows and saltwater flats choose Shallow Blue® lenses. They are ideal for bright and sunny conditions on the open water. If you need to read river bottoms and spot the reds and greens of prized species, choose the VR28® lenses. They eliminate harsh blue light while enhancing the colors you need to work the line with precision. Iridium® lens coating maximizes glare reduction.
