Once ball speed is maximized with launch angle and and spin rates optimized - the final route to elevated driving performance on the course is greater consistency. Step up to the Next Generation of Mizuno's ST Series - the new ST-Z 220 and ST-X 220. Engineered to produce your most efficient drives and highest ball speeds... more often.
ST-X DRIVER
ULTRA-STABLE WITH HIGH DRAW BIAS
A confidence-inspiring, draw-biased driver with heel focused weight location. The ST-X will appeal to players seeking a higher, right to left ball flight. With higher spin rates than its ST-Z counterpart, the ST-X will suit moderate swing speeds, needing help producing a more extended ball flight. A new 20-gram heel biased back weight creates a deeper center of gravity for more efficient, longer drives - more often. Also available as a J-Spec option with ultra-lightweight HELIUM Nanocore shaft for seniors and slower swing speeds.
