Mizuno announce latest generation of Pro Series irons

Mizuno has announced the latest generation of its Mizuno Pro Series of irons. The Mizuno Pro 221, 223, 225 and Fli-Hi are the product of a timeline of exceptional innovations.

Mizuno Pro has always been Mizuno's most forward-thinking iron series with cutting-edge engineering concealed within precise playing profiles that are preferred by the game's elite players.

The Mizuno Pro 221, 223, 225 and Fli-Hi have been designed as elite players’ irons, but with a little rocket fuel added into the mix, they’re destined to make their own mark in iron history.

Showcasing the recent-feel orientated introductions of Grain Flow Forging HD and soft copper underlay, they offer a superb blend of power and playability.

"The concept of Mizuno Pro can be misunderstood - we're not trying to design instant classics or works of art. Mizuno just hides technology incredibly well. This could be perceived as the ultimate betrayal of Mizuno Pro. But the true essence has always been to make history - not be stuck in it," says Chris Voshall, Product Manager at Mizuno Golf.

Mizuno PRO 221 - The Ultimate Muscleback

Inspired by the iconic blades of Mizuno’s past, the Pro 221 has evolved to be more playable through incremental refinements in shape and weight placement.

The irons have been bevelled for the appearance of a shorter face profile and narrower top line, but without loss of mass in the upper blade.

The 221’s are dramatically more compact in the scoring irons than their predecessors. They also feature Mizuno’s shortest CG / shaft axis which is consistent from 3-iron to PW, allowing for controlled shot shaping through the set.

Mizuno PRO 223 - Elite Players Cavity

Mizuno Pro 223 delivers everything tour players need to compete on extended, more demanding layouts - but never thought to ask for. The 223’s conceal a ball speed-enhancing construction within the frame of a compact players cavity.

A completely new technology platform from 4-7 iron combines Mizuno's tested Chromoly Forging and Flow Micro-Slot - An innovation producing extreme ball speeds from a small tour-ready profile. It delivers a face thickness of just 2.4mm.

From 8-PW, Pro 223 are constructed from 1025E Pure Select Mild Carbon Steel for ultimate precision and control.

Mizuno PRO 225 - Hot Metal Blade Design

The Mizuno Pro 225 represents the second generation of Mizuno's staggering Hot Metal Blade and is the most playable of the Mizuno Pro series. It’s more compact than the original with a revised CORTECH multi-thickness face for even quicker ball speeds.

The Hot Metal Blade design features Grain Flow Forged 4135 Chromoly in the face and neck in the 2-8 iron. This combines with a COR Forged Hollow Body and 28.5g Tungsten weight in the 2-7 iron to produce a higher, more stable flight and enhanced ball speed.

In the 9-PW, 1025E Pure Select Mild Carbon Steel is used with stabilizing back weight for greater precision and a more penetrating flight.

Mizuno PRO Fli-Hi - The Authentic Driving Iron

The Mizuno Pro Fli-Hi is designed to be played with a graphite shaft. Relieved of the constraints needed to flow through a complete set, the Mizuno Pro Fli-Hi has a longer head length, a little extra offset and a wider sole than the Mizuno Pro 225 long irons.

With Mizuno's first-ever Maraging MAS1C face in an iron, delivering vastly increased ball speeds, it’s a powerful driving iron.
