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.
“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 Llewellyn, R&D
FEATURES:
- 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
Two weights can be pushed to more extreme positions for ultra-low spin to mid-low spin settings. - COMPACT 440CC PLAYERS PROFILE
An inviting modern pear shape that sits perfectly square in the neutral setting. - NEW BETA RICH TI LFS
The ST-G boasts a new lighter, faster face material – measuring 9% higher in tensile strength (compared to SAT2041) for a complex multi-thickness face geometry. Tour testing demonstrated an average 1.5 mph ball speed improvement compared to SAT2041. - EXPANDED CARBON TOE WRAP
An extension of lightweight carbon into the toe section allows an even greater level of shot shape adjustability. - TOUR TESTED FOR SOUND
A combination of Mizuno’s CORTECH Chamber and internal tuning ribs creates a more solid feel at impact – in the full range of weight settings. - QUICK SWITCH HOSEL
4 degrees of adjustability to fine-tune address and trajectory.

I wanted a specific configuration for my drive and this was easy and straithforward. I had a slight doubt with regards to the swingweitght and the tork wrench and was quickly answered via the chat. The drive was packaged very professionally. Really impressed with the entire process and the product received.

I’m loving these irons. Great feel, great workability, great distance. I was hesitant to buy them because I was worried about yardages being too long. I’m glad I didn’t let that steer me away from these because they are fantastic irons

Bought my first new driver in 6 years, and it was a great decision. Bought the Qi35 in gold to go with my green and gold golf bag. The club head is lighter then my M5, and I am able to work the ball better and more consistency. Best buy of 2025.

I had old sm6 Vokeys and decided it was time for an upgrade. Heard and saw great things about the MG4s and decide to go with them. I purchased 50-SB, 54-SB, and 58-LB and I have to say these things rip. The spin I can achieve with these is incredible. TaylorMade for the win.

Great Replacement set for my 25+ year old original clubs. Quality is great and received them in a week. Took them to the range twice already and am very pleased, looking forward to play some rounds to get a real feel for them.
