The look of Holbrook, from its iconic style to keyhole bridge and metal rivets, has been scaled up to fit larger faces. Even with enhanced sizing for larger faces, it stays comfortable with lightweight O Matter frame material. Pure Plutonite lenses filter out 100% of all UV while XYZ Optics maintains clarity at every angle of view. To help maintain the High Definition Optics (HDO) of Oakley lenses, your new eyewear comes with a specially-woven electrostatic Microclear bag for cleaning and storage. Using it will preserve the superior optical quality of Oakley's pure Plutonite lenses. Hand wash and air-dry the Microclear bag regularly.
