Ultimate sun protection meets striking design with the Oakley SI Holbrook Multicam Black. The lightweight, stress-resistant O-Matter frame is designed to make contact only with the sides of your head and bridge of your nose, creating a fit that won't squeeze or pinch like many other frames that hook the ears. Using Oakley's Plutonite lenses to block 100% of all UVA and UVB rays, these sunglasses feature a reduced side curvature to deliver peripheral sun protection and unparalleled visual clarity. These shades also meet or exceed several ANSI standards for impact resistance and optical clarity. Initially made only for law enforcement officers and military personnel, these sunglasses are now commercially available with the same design features used by tactical professionals.
