The Mizuno ST-Z 230 Driver is a game-changing club that will take your golfing experience to the next level. With its innovative CORTECH Chamber technology, this driver provides an additional source of energy and takes stress away from the clubface. The forged SAT 2041 Beta Ti Face is more resilient than commonly used titanium, and it's engineered even thinner to further reduce stress on the CORTECH Chamber. The unified sole composite allows for a forward weight press of Mizuno's CORTECH Chamber, while the straight flight bias ensures a highly stable, straight ball flight. This driver also features a modern players profile that pushes lower to the ground for low/mid spin performance and aligns square to open. Finally, with its quick switch hosel mechanism offering four degrees of adjustability, you can customize your shot shape with ease.

  • Innovative CORTECH Chamber technology provides an additional source of energy and takes stress away from the clubface

This club is good for players seeking lots of forgiveness in a handsome package. The ST-Z provides high launch and high forgiveness in a club that feels effortless to hit straight. This model had the Kai Li shaft by Mitsubishi Chemical and really unloads easily providing a mid to high ball flight with mid to high spin. At impact you hear... Read more

The Mizuno ST-Z 230 driver features a new CORTECH Chamber that places an internal weight closer to the face to decrease spin rates and increase distances. During my testing of the ST-Z 230, I found it to be incredibly hot off the face, giving me competitive distances to some of the top distance drivers on the market. The ST-Z will... Read more

Nick was great, understood my needs a senior golfer.
5 /5
I was looking for a new driver to bring more consistency and some distance to my game. I discussed club head speed, loft, and distance. I really wanted more consistency over distance, but didn't want to loose to much distance or any. Nick was great on all levels, walk me thru each issue and answered my questions like the pro he is.

Paul was a great help and very responsive. He was quick to answer back to my questions. He sent me a few very affordable options for clubs and it was nice to see someone who just cares about the game and not selling the most expensive set. Definitely will continue my conversation with Paul for any future endeavors with curated!

I’m not sure I would’ve pulled the trigger on this purchase if it wasn’t for Ted’s assistance! He explained every detail of the options he shared and eased every hesitation I had about going with an option I wasn’t as familiar with. He seemed to go out of his way to make sure I was comfortable with the purchase and satisfied with the process. He has a customer for life in me!

Ted was knowledgeable and so helpful for a golf newcomer!
5 /5
I was paired with Ted as my curated expert and I needed guidance on a beginner set of clubs. He asked questions to ensure he would find me options that fit my needs and budget! He was so quick to find me a couple of options within my budget. He also made sure to inform me that due to my smaller height compared to the average female I would need a “petite” instead of the “standard” size clubs, which I never would have known had known had he not mentioned that. Always, Ted was awesome and super helpful and even made sure to check in to see if there was anything I else I needed. Definitely recommend working with him!

John was outstanding!
5 /5
I hadn't golfed in 12 years. Life happened and I just quit playing. I was convinced to be a part of a team in a scramble. I was hooked again and needed some updated clubs. I was a bit intimidated. I wanted to make sure I got clubs that would work for me and be worth the money I spent. I honestly did not know where to start. John answered every question I had and provided me with several great options based on what I told him. I could not be happier. I got a great price for a great set of clubs and look forward to working with John in the future!! Thanks John, you're appreciated man!

Thanks so much Kyle!!
5 /5
I do not golf, but my son is 15 and wants to learn how. I originally was looking for clubs for him as a starter set. Then decided my husband needs to destress and get away from all his "house/lake projects" with friends once in awhile. He used to golf before having kids....when you have more time. Now that he is older I thought it would be good to get a set they can both use. Also a little better quality incase my son keeps growing like he has and will need something for taller height down the road, the set we purchased can then become my husbands.
