Mizuno has introduced its new Pro 221, 223, 225 and Fli-Hi irons which will hit retail on February 3rd, 2022.

“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.” – Chris Voshall, Product Manager, Mizuno Golf.

The Mizuno Pro 221 is a new muscleback iron inspired by iconic Mizuno blades of the past. The Pro 223 is an elite players cavity iron, while the Pro 225 is a hot metal blade design.

Mizuno Pro 221

The Pro 221 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 more compact in the scoring irons than their predecessors while also featuring Mizuno’s shortest CG/shaft axis, which is consistent from 3-iron to PW, in design to allow for controlled shot shaping through the set.

Grain Flow Forged in Hiroshima, Japan, they feature a soft copper underlay in a bid to provide a classic, smooth Mizuno feel at impact.

“We’re obviously working in small increments on a Mizuno muscleback – we have to dig quite deep to get any negative feedback. The copper underlay and Grain Flow forging was such a great foundation on the MP-20. Players with a good eye will enjoy the subtle shape changes through the set – especially the 8, 9, PW” – David Llewellyn– Director of R&D for Mizuno

Mizuno Pro 223

The Mizuno Pro 223 irons 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 designed to produce extreme ball speeds from a small tour-ready profile.

The irons deliver a face thickness of just 2.4mm (vs 2.6mm JPX921 Forged), and from 8-PW, the Pro 223 irons are constructed from 1025E Pure Select Mild Carbon Steel in a bid to offer excellent precision and control.

“The good way to look at the new Mizuno Pro 223 is that we shrunk the JPX921 Forged technology platform to the profile of one of our small player’s cavities – comparable to the MP-62, MP-64 or MP.” – David Llewellyn.

Mizuno Pro 225

The Mizuno Pro 225 represents the second generation of Mizuno’s Hot Metal Blade and is designed to be the most playable of the Mizuno Pro series. The iron is more compact than the original and features a revised Cortech multi-thickness face in a bid to produce 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 – consistently 0.2mm thinner across the face. This combines with a COR Forged Hollow Body and 28.5g Tungsten weight in the 2-7 iron in a bid 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 in design for greater precision and a more penetrating flight.

“The original Hot Metal Blade was the extension of our hybrid iron technology into a full bladed look set. The new Mizuno Pro 225 pushes the profile and size deeper in the realms of the tour – but commits more fully to the pursuit of ball speed,” – David Llewellyn Director of R&D

Mizuno Pro Fli-Hi

A long iron replacement with a priority on ball speed – the Mizuno Pro Fli-Hi is designed to be played with a graphite shaft. 

The Mizuno Pro Fli-Hi features a longer head length, a little extra offset and a wider sole than the Mizuno Pro 225 long irons and includes the brand’s first-ever Maraging MAS1C face in an iron – which is designed to deliver vastly increased ball speeds.

The Pro Fli-Hi comes in 2-4 iron and is right-hand only.

“Over the last couple of seasons, we’ve noticed that there are two types of tour player – those who predominantly use their long iron hybrids into greens and others who use them to hit more fairways. With the Mizuno Pro 225 and Fli-Hi, we’ve got options for both – or to meet changing demands players might encounter at different types of courses.” – Jeff Cook, PGA Tour Manager, Mizuno.
