ST-G 220: The carbon-composite panels in the crown and sole save weight to make room for adjustable weights that fit in heel, toe and deep-center tracks to target preferred ball flights. The new configuration now allows for two central back weights for deeper CG capability, a higher stability, launch and spin, but two weights also can fit in either the extra draw track on the heel or the toe track.
Deeper faced, shorter back to front, but using the full capacity 460cc head size.
NEW MULTI-THICKNESS CORTECH FACE
Refined to maximize the return from Mizuno's Beta Ti face. Ball speeds most noticeably improved low on the clubface.
NEW DUAL WEIGHT CENTRE SLOT
Allows 2 central back weights for deeper CG capability - higher stability, launch and spin.
GREATER DRAW / FADE BIAS
Increased separation between lateral weight tracks.
CONSISTENTLY SOLID FEEDBACK
A tighter range of feel and sound across the weight settings.
QUICK SWITCH ADJUSTABILITY
4 degrees of loft adjustability to fine-tune look and trajectory.
OPTIMIZED WAVE SOLE
Delivers an additional contribution to ball speed - low from the clubface.
