CNC Milled Forged

Mizuno's JPX technology platform provides a different option for serious golfers - a high feel Grain Flow Forged iron, packed with forgiveness and distance properties

The largest of Mizuno's Grain Flow Forged irons, the JPX has a longer profile than its MP counterparts, though a modest offset and top line preserve the traditional Mizuno look at address.

Distance gains are achieved through a unique combination of CNC milling and "under cut forging" that thin the face for improved energy transfer - resulting in the highest COR ever developed in a Mizuno Grain Flow Forged iron. The JPX800 Pro's 'under-cut' also allows an unlikely level of stability and forgiveness for an iron of such modest proportions.

JPX800 Triple Cut Sole

While workability is reigned in through the use of the 'under-cut', the JPX800 Pro's Grain Flow Forged feel is enhanced through the application of Mizuno's Harmonic Impact Technology project - re-enforcing strategic areas for a pure sound at impact.

Mizuno's triple cut sole design is applied to effectively reduce the impact of the wider sole - for effective use from even the tightest cut fairways.

The JPX800 Pro is Grain Flow Forged at Mizuno's exclusive Hiroshima facility for exceptional feel and distance control.

"For a feel orientated player"

"For a feel orientated player willing to trade a little workability for stability from off centre hits, the JPX800 will work beautifully. We've achieved that forgiveness without adding much offset - which is going to appeal to even professionals and single figure players. The fact that ball speeds are upto 2% quicker than our other forgings, puts the JPX800 Pro in a category of its own"
