ST-Z

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.

​

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

​

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

​

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.

​

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

​

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