Developed in hand with Mizuno's tour advisors, yet midsized and playable for all skill levels, the adjustable ST-Z 230 Fairway Woods produce mid-to-low spin and a high launch. The ST-Z 230 Fairways feature Mizuno's new CORTECH Chamber technology. Strategically located close to the face, the CORTECH Chamber encases a stainless steel weight with elastomeric TPU, resulting in decreased spin and an additional energy source that increases ball speed. At the same time, CORTECH reduces stress on the face, granting Mizuno's engineers the ability to construct the face out of MAS1C steel. This high-energy material allows for a thinner, faster face with a complex multi-thickness design that preserves ball speed on mis-hits.If you would like to customize the shafts, grips, lengths or lies give us a call or send an email to Tom@dallasgolf.com. Standard Mizuno warranty applies and satisfaction is guaranteed.
