THE PRECISION HYBRIDMizuno’s JPX Fli-Hi’s are precision hybrids – engineered to directly replace your least reliable long or mid irons. The new Fli-Hi’s wider footprint and material construction deliver an even more playable, high flying alternative than their predecessors. A 17-4 stainless steel face and 431 body delivers an upgrade in ball speed – while maintaining a bendable hosel that allows for adjustments in lie angle.JPX921 Hot Metal ironsThe 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.
