Performance and comfort have been par for the course, but recent advances have put topspin on the proven M Frame™ design. Using the rugged marrow of the Pro M Frame, the new M Frame for golf has been reshaped for a closer float across the eyes. This lightweight articulated eyewear offers the startling clarity of POLARIC ELLIPSOID™ geometry and Iridium® lens coatings that help you read the green in sun or shadow. A low-profile nosepiece maximizes your field of vision, and vented lenses keep you cool through the worst slice. All Oakley eyewear is warranted for one year from the date of purchase against manufacturer defects.
