Mizuno ST-Z 230 Driver

This Driver features:

Cortech Chamber
Forged Sat 2041 Beta Ti Face
Unified Sole Composite

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.

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
