Performance and comfort have been par for the course, but recent advances have put topspin on our 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. Available with vented, interchangeable lenses of pure Pltuonite keep harmful UV rays from playing through.
