ST-G 440 DRIVER

•  CORTECH CHAMBER – The missing piece

•  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 pieces of 7grams 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 440 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 (HIT) 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.
