Mizuno is a brand that is known for crafting some of the best irons in the game, but in recent years, the Japanese company has launched some seriously impressive drivers and the Mizuno ST-Z driver could be its best yet.

Mizuno’s ST Series drivers represent the culmination of its three-year, rapid-fire driver development project. Preceded by the highly acclaimed ST190 and ST200, Mizuno's first drivers widely played by its global tour staff, the ST-Z and ST-X further deploy Mizuno's new SAT2041 Beta Ti face and complex carbon construction to deliver both potent ball speeds and a dense, satisfying sensation at impact.

There are only a handful of players in the professional game who have a Mizuno driver in the bag, but there's no question that the brand is growing in popularity amongst amatuers. However, can the new ST drivers compete with the likes of TaylorMade, Callaway and PING?


Mizuno ST-Z driver - Key Features

SAT2041 stands for Super / Alloy / Titanium / 20% Vanadium / 4% Aluminium / 1% tin, and it offers 17% more tensile strength and 8% more flexibility than traditional 6-4Ti.

A Nippon steel product that was developed over five years as a lightweight, high strength material for the automotive industry and used for complex cycle parts requiring intricate design and an ability to withstand strong forces, SAT2041 has a fine grain structure inherently resistant to fatigue. As a high strength Beta Ti, SAT2041 maintains its characteristics and resists micro fractures for longer than the commonly used 6-4, Alpha Beta Ti.

The ST-Z driver has been designed to be ultra-stable and to offer low-spin efficiency. It has a balanced toe/heel carbon composite construction with deep central back weight – for a spin efficient, straight-line ball flight. It features the second generation of Mizuno's Forged SAT2041 Beta Ti face for potent ball speeds and consistent performance over time.

A balanced use of carbon composite on the sole and a deep central sole weight are biased towards a straight-line flight and low spin efficiency. The ST-Z driver has a wide, low footprint, with a neutral visual lie angle and comes with 4 degrees of quick switch adjustability to fine-tune look and trajectory.

Mizuno ST-Z driver - Looks and Feel

Let's start off with the looks to begin with. Now Mizuno might be known for making beautiful irons but the ST-Z driver is absolutely stunning.

It has a simplistic and classy feel to it, while the carbon crown on the sole of the club gives it that clean, sleek and modern finish.

But looks are only a small part of the overall package, there are other areas that we also need to mention.

Mizuno ST-Z driver - Performance and Forgiveness

Drivers have different sounds to them depending on the brand and the materials used in the club.

Every golfer will have a personal preference with sound, so you'll need to experience it for yourself and not just take our word for it, but we absolutely love the quieter, more muted, sound that the ST-Z driver produces.

Should you buy the Mizuno ST-Z driver?

In terms of data, consistency is key when it comes to drivers. There's no point getting your optimum numbers once every 10 drives, you want to see similar numbers every time.

We can honestly say, the Mizuno ST-Z driver was THE most consistent driver that we tested in 2021. Alex was producing a spin rate of 2020rpm, which is in the lower category, just as this driver promises to do and it was around that number every single time.

If you're thinking of adding a new driver to the bag, we strongly recommend you give this one a try.
