The Mizuno ST-Z builds on the success of the ST200 and offers performance that is a match for anything else currently on the market. With a classic teradrop shaped profile that better plyers will love and appealing confidence inspiring carbon crown, it looks and feels like a driver with another £100 on the price tag. The Mizuno ST-Z driver benefits from an all-new multi thickness Cortech face which has been designed to maximise energy transference and brings large increases in performance especially on low face strikes.
