About the Mizuno JPX EZ
The JPX EZ is the cast game-improvement model of the two-iron JPX EZ family Mizuno launched in the autumn of 2013 below the JPX-825 range. It is a super-oversized head with a very wide sole that carries most of the weighting for an easy, high launch: the 4- through 7-irons use Mizuno's deepest Max Pocket Cavity, while the 8-iron through gap wedge switch to a shallower Deep Pocket Cavity for control, all framed with Harmonic Impact Technology for feel. Lofts are distance-spec for the period — a 32-degree 7-iron and 45-degree pitching wedge — and the stock set ran 4-iron through gap wedge at $700 in steel. The sole is narrower at the heel and much wider toward the toe. Mizuno announced the restyled 2016-model JPX EZ in August 2015, which closes this record. All figures are the men's standard steel-shaft specification.

Frequently asked questions
What is the loft of a Mizuno JPX EZ 7-iron?
The 2013 Mizuno JPX EZ 7-iron has a loft of 32 degrees, a lie of 61.5 degrees and a steel-shaft length of 36.75 inches.
What is the difference between the Mizuno JPX EZ and JPX EZ Forged?
They share the same loft chart, but the EZ is a larger cast head with a wider sole, deeper pocket cavity and much more offset (0.26 inches at the 7-iron against 0.189), while the EZ Forged is Grain Flow Forged from carbon steel for feel.
Why do the Mizuno JPX EZ long irons have negative bounce?
Mizuno listed the 4- and 5-irons at -1 and -0.5 degrees of bounce; with such a wide sole, the negative bounce keeps the leading edge from sitting up at address.
When was the Mizuno JPX EZ made?
The original JPX EZ launched in the autumn of 2013 and was replaced when Mizuno announced the restyled 2016-model JPX EZ in August 2015.
Finding a used set
The Mizuno JPX EZ ran from 2013 to 2015 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
