The Mizuno JPX 800 Pro irons are designed for the optimal blend of forgiveness, distance, and feel. They have the highest COR to date of any Mizuno Grain Flow Forged iron with a CNC milled cavity milling process and provides a low and deep center of gravity. They also feature an aggressive Triple Cut design sole, which results in improved face-to-ball contact from most any lie. The 3-7 irons feature the CNC Milled and Undercut Cavity, while the 8-PW features a solid power bar for improved control and feel. Modal Analysis and Harmonic Impact Technology are employed to produce optimal feel and sound, providing improved feedback for players who demand it.
