Mizuno’s squat, powerful, player’s driver combines the scope to optimize launch and spin with the ball speed enhancements of Mizuno’s CORTECH Chamber.

Two convergent weight tracks allow the ST-G to be anything from a low spin bomber, fade or draw biased or simply a more stable compact driver.

“The ST-G 440cc is very stable in the category of compact driver heads. The addition of Mizuno’s CORTECH Chamber greatly influenced our ability to create more consistent ball speeds across the face.”

• David Llewellyn, R&D

FEATURES:

• CORTECH CHAMBER
  Encases a 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.
• MAX CONVERGENT FAST TRACK
  Two weights can be pushed to more extreme positions for ultra-low spin to mid-low spin settings.
• COMPACT 440CC PLAYERS PROFILE
  An inviting modern pear shape that sits perfectly square in the neutral setting.
• NEW BETA RICH TI LFS
  The ST-G boasts a new lighter, faster face material – measuring 9% higher in tensile strength (compared to SAT2041) for a complex multi-thickness face geometry. Tour testing demonstrated an average 1.5 mph ball speed improvement compared to SAT2041.
• EXPANDED CARBON TOE WRAP
  An extension of lightweight carbon into the toe section allows an even greater level of shot shape adjustability.
• TOUR TESTED FOR SOUND
  A combination of Mizuno’s CORTECH Chamber and internal tuning ribs creates a more solid feel at impact – in the full range of weight settings.
• QUICK SWITCH HOSEL
  4 degrees of adjustability to fine-tune address and trajectory.
