The Mizuno Pro Fli-Hi Long Irons are designed to increase ball speed utilizing new materials and construction techniques. Ball launch is also increased through a heavier Tungsten and more optimal location.
First Nickle Chromoly 4335+ Hollow Body Construction Iron: Utilizing the ultra high strength properties of 4335+ in it’s heat treated state for a high COR face, and well as, the more malleable untreated state for body, thus allowing a bendable hosel.
L-Face Geometry: A more optimized welding technique that allows more sole flex contribution to COR and thinner top line.
Multi-Thickness CORTECH Face: Thickness profile developed through advanced CAE analysis for larger CORAREA and higher peak COR.
Harmonic Impact Technology: Through study of the model properties of the head, strategic use of internal sound ribs, provides solid impact sound.
Black Ion Satin Finish: Frames the ball perfectly at address and provides a slimmer, more compact look.
