JPX 921 Hot Metal Iron
CHROMOLOY
The JPX 921 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 JPX 921 has the most complex face geometry to date for additional energy from the clubface.
FASTER AND FASTER CHROMOLY 4140M
Our 3rd generation of designing and manufacturing irons using Chromoly – now taken to its limits. A re-engineered CORTECH face, is now 0.2mm thinner across the center point.
SEAMLESS CUP FACE
A new variable thickness sole design allows the leading edge to act as a hinge, resulting in greater face flex and ball speeds.
HARMONIC IMPACT
Predicting vibration patters dictated 3 additional sound ribs – producing a more solid sensation.
PEARL BRUSH FINISH
Anti-glare to minimize distractions over the ball.
STABILITY FRAME
Additional perimeter weighting with toe bias for stability from off center strikes.
JPX FLI-HI
THE PRECISION HYBRID
The JPX 921 Hot Metal irons pair Mizuno’s fastest ever ball speeds with a piercingly straight, ball flight and controllable landing angles.

FAIRWAY WOOD TO HYBRID PROFILE
The 20 degree (#4) has a wider fairway type profile, graduating to a tighter hybrid type shaped 29 degree (#7) with a deeper face.
NEW 17-4 STAINLESS STEEL FACE AND 431 BODY
Entirely new construction creates a lighter crown for higher ball flight – with a bendable neck for lie angle adjustment.
MORE CONSISTENT BALLS SPEEDS
A re-engineered Wave Soleplate expands the high ball speed area of the Fli-Hi’s clubface.
MORE RELIABLE DISTANCE GAPS
A deeper center of gravity than the replaced iron – means more predictable launch, spin and distance gaps.
