Mizuno Pro 243 Irons

Crafted with the meticulous precision of a samurai sword, the Mizuno Pro 243 irons are a testament to the enduring partnership between Mizuno's R&D team and its legendary Grain Flow Forging plant in Hiroshima, Japan. This collaboration has yielded a masterpiece of clubmaking, one that's both more compact and precise than its predecessor, yet faster off the face and undeniably satisfying at impact.
