The Oakley Holbrook (OO9102) squarish sunglasses have borne the heritage stamp while blending modern materials. Its frame, molded from O-Matter™, is light but durable and adorned with metal rivets and a Square O icon, for that retro touch. The lenses use Oakley's HDO® (High Definition Optics) and come in Prizm™, Polarized, and Iridium® options for sharpening contrast and reducing glare.
