Mizuno ST-Z Driver

Mizuno ST-Z Driver

Ultra-stable with low spin efficiency

A balanced toe/heel carbon composite construction with deep central back weight – for a spin efficient, straight-line ball flight. Built upon the 2nd generation of Mizuno's Forged SAT2041 Beta Ti face – for potent ball speeds and consistent performance over time.


20% Vanadium / 4% Aluminium / 1% Sn

Highly resilient Forged SAT2041 Beta Ti Face

As a high strength Beta Ti, SAT2041 maintains its characteristics and resists micro fractures for longer than the commonly used 6-4 Ti.

New Multi-thickness CORTECH Face structure

Refined to maximize the return from Mizuno's Beta Ti face. Ball speeds most noticeably improved low on the clubface.

'Dense' or solid feedback

The majority of Mizuno's tour players expressed a preference for more dense feedback through impact. Mizuno's engineers spent a year finessing the sound to a more muted, powerful tone.

Z Axis design for straight-line flight

Balanced use of carbon composite on the sole and deep central sole weight are biased towards a straight-line flight and low spin efficiency.

Optimized Wave Sole Plate

Delivers an additional contribution to ball speed – low from the clubface.

Wide, low footprint

With neutral visual lie angle.


4 degrees of loft adjustability to fine-tune look and trajectory.
