Mizuno ST-Z 220 Driver — 9.5° Stiff Flex Right Hand

The Mizuno ST-Z 220 Driver is designed for the better player who values control and workability over maximum forgiveness — the driver that complements Mizuno’s reputation for precision engineering carried over from their legendary iron line. ST-Z stands for Speed Technology Zero-Center: the design principle of placing the CG directly behind the sweet spot rather than low and deep as forgiveness-focused drivers do. The SP700 forged titanium face delivers Mizuno’s characteristic clean, responsive impact feel with excellent ball speed from a material that’s more difficult to work with than cast titanium but produces superior consistency. A 220cc designation in the name indicates a head volume that, while still at standard 460cc, uses a more compact footprint for an aerodynamically cleaner profile that reduces drag through the hitting zone. The carbon crown saves mass for CG optimization, and adjustable weight positions allow draw or neutral flight preference. For the golfer who has moved past max-forgiveness and wants a driver that responds to skill, the ST-Z 220 at its current price is a compelling Mizuno statement.
