The Z 585 is slightly more forgiving and features a high-strength steel face insert in the forged clubhead for higher COR and ballspeed at impact. A new internal “speed groove” behind the clubface further enhances face flex across a larger area of the hitting zone for extra forgiveness on off-center hits.
The JPX 919 Hot Metal is available in 4-LW in both right and left hand options with a wide variety of premium no-upcharge shafts and grips. All three new JPX 919 irons are available through Mizuno’s Performance Fitting System and can be mixed and matched depending on individual player needs and preferences.
Replacing the previous Z 565 model is the new Z 585 which is designed to produce a higher straighter ball flight than the Z 785 with more forgiveness on strikes away from the enter of the clubface.
