Mizuno’s JPX923 irons are engineered for custom performance. Five unique iron models created from three specific metals - based on Swing DNA data from over 350,000 real golfers. The expanded head options combine with one of over 50 custom shafts for specific trajectory, ball speed and ease of use. This creates options for elite tour players, slow swinging amateurs and every player in between.
Introducing Nickel Chromoly – A new material with so much additional ball speed, our engineers switched their focus to feel and stopping power. At 35% stronger than our original Hot Metal material, 4335 Nickel Chromoly enables a high-energy 8% thinner clubface. Combined with Mizuno’s vibration controlling V-Chassis and deep CG design, the JPX923 Hot Metal irons are as enjoyable and controllable as they are long.
