Mizuno's new ST-X 220 brings extra distance, slight draw bias and a high flight for the player looking for the modern low spinning driver. The exceptional stability on off-center strikes allows you to deliver your best more often. X-Axis design pushes weight deep in the heel for a higher draw-bias flight, with a slightly more rounded profile encouraging higher launch and medium spin performance. A highly resilient forged titanium face features multi-thickness CORTECH for increased ball speeds and resistance to micro-fractures. A 20g weight is placed in the heel to create a deeper CG to give you longer, more efficient drives.
