The Oakley SI Ballistic Det Cord™ Sunglasses offer a blend of ballistic protection and style that's ideal for aggressive environments. These tactical sunglasses are compliant with MIL-MRF-32432 and ANSI Z87.1 standards for protection against high mass, high-velocity impacts. The ear stems feature thin stem technology for compatibility with your comms equipment, and the rubberized unobtanium nose piece keeps the frame firmly in place. Additionally, these Oakley sunglasses enhance color and contrast with Prizm™ lenses and have an anti-fog coating for unhindered vision.
