The Oakley Men's Batwolf Sunglasses are about original style; and it s a clean look of authenticity that makes the statement. A single continuous lens sweeps across a comfortably lightweight O MATTER frame. The icons are interchangeable and two sets are included. They stay secure with hidden latches until you re ready to swap them out with a new color. It s fast and easy; and it lets you change your look in seconds. We also designed BATWOLF with dual cam hinges that blend smoothly into the sculpture. This unique sunglass has a Three-Point Fit that keeps the optics in precise alignment; and we designed the frame to fit comfortably on medium to large faces.
