The Mizuno ST-Z 230 Driver. Straight, Stable and Low Spinning.

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.
