Mizuno ST-Z 220 Driver

With a balanced toe/heel carbon construction and central back weight, Mizuno's ST-Z 220 driver encourages a low spinning, efficient straight ball flight. The modern ground hugging 460cc profile is both confidence inspiring and appealing to elite players. While a heavier 20-gram back weight creates a deeper centre of gravity for more efficient performance, more often.

Features & Benefits:

• More Performance - More Often
  The ST-Z delivers your optimum more often through exceptional stability from off-centre strikes. An expansion of the carbon sole area by 40% and thinning out the Titanium portion. Alongside a near doubling of the stabilising back weight.
• Straight Flight Bias
  Mizuno’s Z-Axis design - weight is evenly distributed across toe and heel, encouraging a low spinning stable straight flight.
• Modern Players Profile
  Full 460cc volume pushed slightly to the ground for higher launch and low/mid spin performance. Visually square to slightly open in the standard-setting.
• Highly Resilient Forged SAT2041 Beta Ti face
  Maintains its characteristics and resists micro-fractures longer than the commonly used 6-4 Ti.  Elevated through a multi-thickness CORTECH design for increased ball speeds.
• Engineered For Solid Feel
  Mizuno's Harmonic Impact Research identifies and isolates vibration patterns that elite players associate with a preferred 'solid' feel. Knowledge of exact, preferred vibrations allows Mizuno to build sound into the design.
• Optimised Wave Sole
  Delivers an additional contribution to ball speeds, particularly from low on the clubface.
• Quick Switch Adjustability
  With 4 degrees of loft adjustability to fine-tune launch and trajectory.

Specifications:

• Right Hand: 9.5 and 10.5 degrees.
• Left Hand: 9.5 degrees only.
