Big coverage with a revolutionary interchangeable design is what the Smith PIVLock V90 Max Sunglasses are all about. The ultralight, rimless design uses removable hinging temple arms and a removable bridge piece attached to a one-piece carbonic TLT lens. When lighting conditions change, snap off the arms and nose piece, and reattach them to another of the three included lenses. A sweat-seal lens coating resists moisture and oils, while the hydrophilic nose and temple pads keep your shades snugly secured in any conditions.
