Taylormade M4 Iron Set Men's Steel Shaft 2018
INTRODUCING RIBCOR TECHNOLOGY
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 ballspeed and promote straighter shots.
Speed Pocket technology improves low-face flexibility to deliver more ballspeed in the key area where golfers commonly mis-hit.
Face Slots enhance face flexibility in the heel and toe areas to preserve ballspeed on mis-hits for greater consistency.
The Fluted Hosel and 360 Undercut technologies produce discretionary weight that has been relocated low in the clubhead to improve launch, spin, and forgiveness.
