ZX4 is the new face of forgiveness. Hollow for distance, and sharp at address for game improvement playability without sacrifice.
A milled pattern on the backside of ZX4's face maximizes COR for more ball speed and more distance on every shot.
ZX4's hollow design gives you enough forgiveness to strike the ball across the face while still enjoying high shots that fly straight and find their targets.
Tungsten in the base of ZX4's long and mid irons (4i-7i) lowers its center of gravity for a higher launch. A forged HT1770 Steel face enhances speed and distance while a 431 Steel body absorbs vibration for softer feel.
V-shaped soles glide smoothly through turf, even if you strike slightly behind the ball. ZX4 Irons also feature the resurgence of our popular sole notches.
Grooves in the 8i through PW are sharper, narrower, and deeper for more spin and stopping power on approach shots into the green.
