Mizuno ST-Z 230 Hybrid

A low spinning, high launching, adjustable hybrid – developed hand in hand with our tour advisors, yet playable for all levels. Utilizing a high energy MAS1C steel face boosted by Mizuno’s CORTECH Chamber for exceptional ball speeds and powerful, solid sensation at impact. A slightly larger, more playable footprint than its predecessor the CLK.

Technical Details

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.

Waffle crown and thick sole weight

Engineered to create a low sweet spot and deep centre of gravity, for high stable launch and efficient spin rates.

High energy MAS1C steel face

Reworked with a new multi-thickness design – made possible through the face support of Mizuno’s CORTECH Chamber.

Quick Switch Hosel

4 degrees of adjustability.
