Mizuno ST-G Driver
A lot of people forget that Mizuno was the first OEM to produce a driver with an adjustable sliding weight track, and although it has gone through a number of iterations, it is back with the 2024 ST-G to help adjust ball flight and dial-in spin. The sliding weight track isn’t the only adjustable technology either, because both the fairway woods and the driver are also outfitted with Mizuno’s quick switch adjustable hosel.
You need to hit the ball with something, and to help the face of the ST-G driver better deliver more energy across a larger area the engineers at Mizuno utilize a beta-rich Ti LFS material. This titanium alloy offers up a 9 percent higher tensile strength compared to SAT2041 which gave designers the opportunity to push the multi-thickness face geometry further.

According to Mizuno, tour testing demonstrated an average 1.5 mph ball speed increase compared using the SAT2041 material. Now behind the face and on the sole is the Cortech Chamber which houses a stainless steel weight encased in an elastomeric TPU. This filed slot removes stress from the club face to create more flex, while also positioning more mass near the face to lower spin and offer a powerful sound at impact.
The ST-Max features a larger address profile, but what truly separates the ST-Max from the X, the Z and the newly released G models is how the engineers at Mizuno have optimized the geometry of the head for forgiveness, all while maintaining the same 460cc volume by making it shallower and longer heel to toe.
