Featuring a more rounded silhouette than the original Holbrook, the Oakley Holbrook R Prizm Sunglasses are the slightly larger version that packs more performance than you'd expect from a lifestyle look. Oakley's High Definition Optics technology enhances the plutonite lenses to deliver an extremely clear field of view. Prizm technology further improves it by enhancing the colors and details you see. The O-Matter frame is lightweight and comfortable to wear for long periods of time, and it features Unobtanium nose and temple pads to help the frame stay in place.
