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 CHAMBEREncases 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 TRACKTwo weights can be pushed to more extreme positions for ultra-low spin to mid-low spin settings. COMPACT 440CC PLAYERS PROFILEAn inviting modern pear shape that sits perfectly square in the neutral setting. NEW BETA RICH TI LFSThe 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 WRAPAn extension of lightweight carbon into the toe section allows an even greater level of shot shape adjustability. TOUR TESTED FOR SOUNDA combination of Mizuno’s CORTECH Chamber and internal tuning ribs creates a more solid feel at impact – in the full range of weight settings.
