ULTRA LOW SPIN TOUR PERFORMANCE

Mizuno's squat, powerful, player's driver combines the scope to optimize launch and spin with the ball speed enhancements of Mizuno's CORTECH Chamber. Two convergent weight tracks allow the ST-G to be anything from a low spin bomber, fade or draw biased or simply a more stable compact driver.

Mizuno ST-G Driver
The ST-G 440cc is very stable in the category of compact driver heads. The addition of Mizuno's CORTECH Chamber greatly influenced our ability to create more consistent ball speeds across the face. DAVID LLWELLEYN - DIRECTOR OF R&D

Cortech Chamber Encases a stainless steel weight with elastomeric TPU - taking stress from the clubface and creating an additional energy source. At the same time locating weight closer to the clubface to reduce spin rates. While contributing to a more solid, powerful sensation at impact.

Max Convergent Fast Track

We've had a significant surge in tour usage for Mizuno drivers over the last few years, and the addition of a more compact 440cc ultra-low spin option will only accelerate that trend. CHRIS VOSHALL - DIRECTOR OF PRODUCT
