Mizuno ST-G Driver

Who’s It For?

Mizuno’s ST-G driver is not like most drivers on the market, and it is surely different from the ST-Z and ST-X drivers that Mizuno released early in 2023. Of note, the ST-G driver features a smaller clubhead volume that produces lower spin, and increased adjustment capabilities. Ultimately, these features cater more toward a golfer with higher swing speeds and/or golfers who like to tinker with adjustable weights on their driver.

The Tech Story

The Mizuno ST-G driver is powered by a player-preferred 440cc Pear Shape clubhead design with a deep face to allow for more discretionary weight, which provided Mizuno engineers wiggle room to enhance spin characteristics, whether you prefer mid-low spin or very low spin. The Fast Track and CORTECH Chamber allow for maximum adjustability to dial in optimal launch and spin. There’s also a new clubface material – Forged Beta Rich Ti-LFS, which is lighter, faster, and stronger. The clubface also features a CORTECH multi-thickness design that optimizes ball speed and adds forgiveness. The expanded wrap around composite crown allows for neutral, right, and left biases to be created. And lastly, thanks to Quick Switch Adjustability, there is 4 degrees of loft adjustability to fine-tune the ST-G.
