A straight bias driver with great stability on off centre hits. Similar in look and character to the previous ST-Z. Boosted by the CORTECH Chamber to be faster from the face, spin less and deliver an incredible, solid sensation at impact.

Features & Benefits

• CORTECH Chamber: Boosts energy transfer and reduces spin by placing weight closer to the clubface. It delivers a solid, powerful feel at impact.
• Forged SAT 2041 Beta Ti Face: More resilient than commonly used 6-4 Ti, with more complex multi-thickness design – made possible by Mizuno’s CORTECH Chamber.
• Unified Sole Composite: Carbon sole plate now a single piece to allow weight to be pushed to the extremes for overall stability.
