Introducing the new MP-58 irons with revolutionary DUAL MUSCLE TITANIUM™ Technology! During the complex Grain Flow Forging process, a high-tech Titanium metal is forged into the outer muscle of the iron, which not only delivers the feel, workability and shape every MP player desires, but also takes playability in an MP iron to a whole new technological level. The light weight characteristics of the pure Titanium utilized in the MP-58s allow for an ideal amount of thickness behind the impact area to ensure the legendary soft, solid and consistent feel one expects from a Mizuno iron, while simultaneously providing a dramatic increase in perimeter weighting for enhanced playability. The MP-58 irons achieve the rare combination of a penetrating ball flight, increased MOI, and superior feel, all in the ultimate player’s head shape.
