A breakthrough innovation in irons performance; RIBCOR is designed to help you hit it LONGER, HIGHER, and STRAIGHTER. RIBCOR localizes face flexibility, transferring more energy to the ball to increase ball speed and promote straighter shots.
Speed Pocket technology improves low-face flexibility to deliver more ball speed in the key area where golfers commonly mis-hit. Face Slots enhance face flexibility in the heel and toe areas to preserve ball speed on mis-hits for greater consistency.
