Mizuno ST-X 220 Golf Driver

Mizuno ST-X 220 Golf Driver

The Mizuno ST-X 220 Golf Driver is a metal wood option that has been created for golfers who want even more ball speed while being able to experience extra forgiveness and stability. 

The club is designed with a large carbon fibre crown which also features carbon fibre in the heel and toes areas of the sole. The amount of carbon fibre used in the sole is around 40% more than in the previous design, which has meant that a lot of weight has been saved. 

Weight saving in the sole has allowed designers to adjust weighting in other areas in an attempt to positively influence your performance when using this Mizuno Driver. To demonstrate the weight-saving innovation, Mizuno increased the size of the stainless-steel weight that is placed in the back of the club by 80%.

In the sole, Mizuno engineers have used Wave Technology for additional ball speed. A series of ridges are used in the button of the head to allow for the lower section of the face to flex more on shots that strike lower on the face creating high ball speeds. 

The face used on the ST-X 220 uses a new high strength SAT2041 beta titanium face, designed to vary in thickness across the entire face. The Mizuno ST-X 220’s beta-titanium is an alloy that offers incredible flexibility and strength, 17% stronger than the material used in the Mizuno ST180 and ST190 drivers. 

Using this alloy means that the face of the driver is much more flexible, so when the face springs back after connecting with the golf ball it will be able to do so faster and with an extra burst of energy to carry the ball even further. 

The ST-X 220 has been designed to work in tandem with Mizuno’s FUSION 39 gram graphite shaft. This lightweight shaft is perfectly suited with the head design to get as much ball speed and distance as possible, without conceding any stability or control. 

All of this has been combined together for Mizuno to offer golfers a driver that will produce the most efficient drives and the highest ball speed consistently.
