Mizuno has introduced new golf clubs, including the ST-Z 220 and ST-X 220 drivers, fairway woods, and hybrids. The new releases have been showcased in several first look reviews, with some outlets also reviewing the individual components, such as the fairway woods. However, there is some inconsistency in the model numbers mentioned, with one outlet referencing the ST-Z 230 fairway wood, which may indicate a separate or related product.
