Why Mizuno JPX 800 Irons Is So Hot?


The incredulous look on Ryder Cup star Luke Donald’s face when he first hit the latest Mizuno JPX-800 irons spoke volumes for its impact on the World’s No.8 golfer.


As Mizuno’s leading-ranked staff player, he had been lined up to give his endorsement to the MP-63 irons he plans to play on Tour later in the year but during a break in filming a test session, Donald also grabbed hold of a 6-iron from a set of JPX-800s, the clubs aimed at the improving club golfer.

Mizuno says the JPX forged model offers a different option for serious golfers with a unique combination of CNC milling and under cut forging that thin the face for improved energy transfer.
A serious looking iron with ‘Balanced Performance’ the JPX800 is Mizuno’sfirst to utilize its JPX exotic technology platform. ‘Balanced Performance’ is the result of a project to create an iron with strengths in a number of key criteria (feel, control, forgiveness, distance, profile) without one compromising another.


The JPX-800 is an incredible iron that’s hard to pigeonhole. To achieve these ball speeds and MOI numbers (stability at impact), you’d expect to compromise by adding lots of offset or thick top and bottom edges. But our design challenge was to pack all this performance into a head shape that a Tour player wouldn’t reject. It delivers the magical combination of being Mizuno’s most forgiving and longest iron of all time. 


Its look from address and solid feel at impact will have single figure players questioning their choice of iron. The visible distance gains of this irons are achieved by combining Mizuno’s Hot Metal approach – incorporating a new manufacturing process for a thinner, more uniform iron face. An exotic pocket cavity, with multiple thickness levels and an external power bar add the highest measurable levels of forgiveness (MOI) achieved in a Mizuno iron to date.


To be frank, I felt comfortable taking the JPX-800’s to the my ball with confidence. Unlike some game improvement clubs- there was a good amount of workability available to me as well. I don’t have enough skill to sit on the range hitting cuts and draws consistently, but I can tinker enough to know that a good golfer shouldn’t be afraid to take on these clubs.
