TaylorMade M4 Iron Set

The new TaylorMade M4 irons feature RIBCOR technology which localises face flexibility in the hitting area, transferring more energy to the ball to increase distance and accuracy.
RIBCOR technology also stiffens the perimeter of the head creating a more rigid structure, enhancing sound and feel.
Forgiveness and MOI are increased 24% through optimized heel and toe weighting.
A new Speed Pocket and ultra-thin leading edge works in conjuction to increase speed on low-face shots.
Fluted Hosel and 360° undercut produce discretionary weight, which is relocated low and back in the clubhead for a lower CG location and easy launch and increased distance and consistency.
