Mizuno JPX 921 Hot Metal Pro Iron Set

Who’s It For?

The Mizuno JPX iron families have brought a modern appearance to a brand that has been most famously successful in creating beautiful, traditionally-shaped irons. The JPX 921 family, new in 2020, builds off some of the construction techniques used in the JPX 919 family to bolster performance. Of the four models in the JPX 921 family, the JPX 921 Hot Metal Pro irons are built with similar DNA as the standard JPX 921 Hot Metal game-improvement model, but in a smaller, more compact shape to appeal to players that don’t want to see a larger profile at address.

The Tech Story

The JPX 921 Hot Metal Pro irons are the fastest ever created by Mizuno. It’s the third generation of the JPX irons that utilizes the resilience of Chromoly, and the new and improved engineering behind the JPX 921 irons, in particular, created a more complex face geometry to provide added ball speed. Essentially, Chromoly is now being taken to the limit. The re-engineered CORTECH clubface is now 0.2mm thinner, improving the ball speed at impact. Meanwhile, a variable thickness sole design allows the leading edge to act as a hinge to improve face flexing for more distance. The Stability Frame consists of extreme perimeter weighting with added toe bias to add both performance and better feel on mis-hits. The more compact head shape of the JPX 921 Hot Metal Pro will also enhance a bit of control and workability compared to the standard JPX 921 Hot Metal.
