Kevin VanDam didn't build his reputation as the best competitive fisherman by taking shortcuts with his gear. He wants the best and Oakley delivers with its polarized Flak Jacket series sunglasses. The interchangeable lenses optimize performance in any environment. Frames are made of lightweight, stress-resistant O Matter® material. A 8.75 base curvature optimizes peripheral vision and side protection. XYZ Optics® extends razor-sharp vision all the way to the lens periphery. All lenses are treated with a hydrophobic/oleophobic anti-smudge coating. Three-point fit holds lenses in precise optical alignment. Plutonite® lenses filter 100% of UVA/UVB/UVC and harmful blue light up to 400nm. Optical precision and performance for lenses meets all ANSI Z87.1 standards. Impact resistance meets all ANSI Z87.1 standards for high-mass and high-velocity impacts. Includes sports-specific Oakley Soft Vault with capacity for extra lenses and two sizes of nose pads.
