A straight bias driver with great stability on off centre hits. Similar in look and character to the previous ST-Z.
Boosted by the CORTECH Chamber to be faster from the face, spin less and deliver an incredible, solid sensation at impact.
CORETECH CHAMBER
Mizuno’s CORTECH Chamber encases a dense stainless steel weight with elastomeric TPU – taking stress from the clubface and creating an additional energy source. At the same time locating weight closer to the clubface to reduce spin rates. While contributing to a more solid, powerful sensation at impact.
FORGED SAT 2041 BETA TI FACE
More resilient than commonly used 6-4 Ti, with more complex multi-thickness design – made possible by Mizuno’s CORTECH Chamber.
UNIFIED SOLE COMPOSITE
Carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability.
STRAIGHT FLIGHT BIAS
Mass spread evenly to encourage a highly stable, straight ball flight.
MODERN PLAYERS PROFILE
Pushed lower to the ground for low / mid spin performance and aligns square to open.
QUICK SWITCH HOSEL
4 degrees of adjustability.
