The new Mizuno Pro 221 Irons is crafted to be more playable with an iconic muscleback design. The irons are expertly beveled for a shorter face profile and narrower top line without sacrificing mass in the upper blade. A microlayer of copper is built underneath the Nickel Chrome top to bring you the purest and softest feel. The Pro 221 features Mizunos shortest CG/shaft axis and is consistent throughout the set to allow better control of fades and draws. These irons are evolved to be more playable through a process of incremental refinements in shape and weight placement.
