A confidence inspiring hybrid – engineered to produce a higher, draw biased flight. The ST-X hybrids are suited for moderate swing speed players who need elevated launch to reach both their optimal distance and controlled landing angles.
“The ST-X is a great hybrid option for players with moderate ball speeds. With the new thinner face and internal weighting it’s a nice alternative that will suit a lot of amateur golfers.”CHRIS VOSHALL, DIRECTOR OF PRODUCT
Mizuno’s X-Axis design – ultra light waffle crown, with deep internal weighting, encourages a high draw biased flight.
At 1.8mm Mizuno’s thinnest hybrid face to date – with the highest recorded ball speeds from centre strikes (compare to previous ST-X and CLK).
Mizuno's Harmonic Impact Research identifies and isolates vibration patterns that elite players associate with a preferred 'solid' feel. Knowledge of exact, preferred vibrations allows Mizuno to build sound into the design.
Hybrid specific design helps create higher ball speeds from low on the face – suited to strikes directly from the turf.
