Made with Oakley's new SwitchLock system, the Jawbone Sunglasses ($TBA) allows for rapid lens changes with minimal effort. This unique sports frame design uses a locking mechanism and hinge that mechanically captures and secure the lenses with virtually zero tension to minimize optical distortion. The Jawbone features Oakley's XYZ lens optics, Unobtainium nosepiece and Hydrophobic lens coating that repels dust, water, skin oils and sunscreens. [source]
