Mizuno ST-Z 230 Driver

CORTECH 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.

Straight Flight Bias

• CG is positioned further back in the head along the neutral Z axis for a low spin, straight trajectory with launch stability.

Modern Players Profile

• Pushed lower to the ground for low / mid spin performance and aligns square to open.

Multi-Thickness CORTECH Face

• Refined to maximize the return from Mizuno's Beta Ti face. Ball speeds most noticeably improved low on the clubface.

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.

HIT Tuned Impact Sound

• Strategically placed internal sound ribs tune the impact sound to the appropriate frequency and sound pressure.

Quick Switch Hosel

• Offers 4 degrees of adjustability
