What Mizuno Say:
STRAIGHT, STABLE AND LOW SPINNING. A straight bias driver with great stability on off center 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.

Features & Benefits:

• 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 - Full 460cc volume pushed slightly to the ground for higher launch and low/mid spin performance. Visually square to slightly open in the standard-setting.


• Quick Switch Adjustability - With 4 degrees of loft adjustability to fine-tune launch and trajectory.
