So lightweight, you’ll think the name refers to gravity. We reengineered ZERO™ S sunglasses with a sleeker, more aerodynamic sculpt that maps better to cranial contours. Lens configuration includes larger UNOBTAINIUM® earsocks to enhance comfort and grip. The low-profile nosepiece and open-edge lenses unlock your range of view. The application of HIGH DEFINITION OPTICS® (HDO®) allows the lens to maintain optical clarity when the world blasts by in a high-velocity blur. In addition to the sports-specific nose piece pictured on the eyewear above, low-profile ZERO™ Nose Pads are included to reconfigure the frame for street wear.
