ST-Z 230 DRIVER
STRAIGHT, STABLE AND LOW SPINNING
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.

Mizuno’s CORTECH Chamber encases a 3 gram stainless steel weight with elastomeric TPU – taking stress from the clubface and creating an additional source of energy.

Balanced Composite for neutral weight distribution

Design focus is a combination of deeper CG and shorter CG distance for a balance of workability in both directions while providing higher MOI and mid/low spin.


Features

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.

UNIFIED SOLE COMPOSITE
Carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability.

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

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.

STRAIGHT FLIGHT BIAS
Mass spread evenly to encourage a highly stable, straight ball flight.

QUICK SWITCH HOSEL
4 degrees of adjustability.
