We improved our golf specific Zeros™ by arcing the earstems closer to the skull and streamlining the architecture with an integrated, asymmetrical hinge. The low-profile nosepiece and open-edge lenses let you address the ball without craning your neck. Larger Unobtainium™ earsocks enhance comfort and increase grip during perspiration. POLARIC ELLIPSOID™ geometry and Iridium™ coatings keep the course contours in critical focus.
