The JPX921 Hot Metal irons pair Mizuno's fastest ever ball speeds with a piercingly straight ball-flight and controllable landing angles.

The 3rd generation of Mizuno irons to utilize the resilience of Chromoly - the JPX921 has the most complex face geometry to date for additional energy from the clubface. The Pro version of the JPX 921 Hot Metal features a more compact profile with reduced offset when compared to the regular version.
