STRAIGHT DISTANCE AT ITS CORE
M4 irons unlock a new level of straightness, distance, and forgiveness in a product designed to be the longest in our irons lineup.
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.
“We packed this iron with our key performance technologies such as RibCOR, Face Slots, Speed Pocket, 180 Fluted Hosel, and tungsten weighting in a very low-CG package intended for the better player looking for more distance. The shaping has been modified as compared to prior models in this category. The M3 iron features a smaller profile, thinner sole, topline, and new leading edge to inspire confidence and allow for precision where it matters most.”
