Mizuno ST-Z 230 Driver

The Mizuno ST-Z Driver is 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 and the 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.
