Full set of 13 grips. For golfers with higher swing speeds seeking a high-performance grip to enhance shot-making from tee-to-green, Sonar Tour Calibrate features reminder technology to promote consistent hand placement and greater control of the club to better square the face at impact. Calibrate Technology delivers a more pronounced and conforming reminder grip, providing golfers optimal hand placement, club face awareness, and control. It is purposefully engineered with Lamkin’s proprietary tacky Genesis Material in a slightly firmer durometer and Fingerprint Technology for enhanced torsion control and consistent feel in any weather.
