Mizuno ST-Z 230 Driver

Quick Switch Adjustability
CORTECH Chamber
Straight, Stable and Low Spinning

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.

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 while locating weight closer to the clubface to reduce spin rates. This also contributes to a more solid, powerful sensation at impact.

FORGED SAT 2041 BETA TI FACE: More resilient than commonly used 6-4 Ti, with a more complex multi-thickness design – made possible by Mizuno’s CORTECH Chamber.

UNIFIED SOLE COMPOSITE: The carbon sole plate is now a single piece to allow weight to be pushed to 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 aligned square to open.

QUICK SWITCH HOSEL: 4 degrees of adjustability.
