Mizuno has announced an upgrade to its stunning MP iron range for the 2022 season and they come with an all-new name too, as the Japanese brand are now referring to their elite players irons as the Mizuno Pro Series.

Mizuno Pro Series Irons 2021

The Mizuno Pro 221, 223, 225 and Fli-Hi have all been designed with the best players in mind, but still include plenty of cutting edge technology under the hood to provide a perfect blend of power and playability, as proven by the Gran Flow Forging HD and soft copper underlay.

Mizuno Pro Series Irons 2021

Mizuno Pro 221 is described as the ultimate muscleback iron, inspired by iconic blades of the past, Pro 223 is an elite players cavity iron and Pro 225 is a hot metal blade design, whilst the Fli-Hi is an 'authentic driving iron'.

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.

Mizuno Pro 221 Irons

Said to be inspired by iconic Mizuno blades from down the years, the Pro 221 has evolved to provide more playability through 'incremental refinements' in both shape and weight placement.

The irons have been bevelled to give the look of a shorter face profile and a narrower top line, without taking away mass from the upper section of the blade.

The 221 irons are much more compact in the shorter scoring irons than the MP20s. They feature Mizuno's shortest CG/shaft axis from 3 iron all the way down to PW, encouraging controlled shot shaping throughout the set.

Grain Flow Forged in Hiroshima, Japan, the irons feature a soft copper underlay which provides that unique Mizuno feel at impact.

The Pro 221 irons are available in 3-PW at £165 per iron.

Mizuno Pro 223 Irons

Mizuno says that the 223 is an iron which is aimed to give tour players everything they need to compete on extended, more demanding layouts - but never thought to ask for.

This is done by enhancing ball speed whilst keeping the frame of a compact cavity iron. The 4-7 irons combine Chromoly Forging and Flow Micro-Slot to produce higher ball speeds whilst retaining the sleek profile.

The iron delivers a face thickness of just 2.4mm, compared to 2.6mm in the JPX921 Forged irons.

From 8-PW the Pro 223 irons are constructed from 1025E Carbon Steel for ultimate 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.

The Pro 223 irons are available in 4-GW at £180 per iron.

Mizuno Pro 225 Irons

The Mizuno Pro 225 is the second generation of Mizuno's Hot Metal Blade and so is the most playable of the Mizuno Pro Series. It's more compact than the original model, with an improved Cortech multi-thickness face which is engineered to provide even faster ball speeds.

This Hot Metal Blade design features Grain Flow Forged 4135 Chromoly in the face and neck from 2-8 iron, which is 0.2mm thinner across the face than the previous iron.

This combines with a COR Forged Hollow Body and 28.5g of tungsten weight in the 2-7 iron to produce a higher, more stable ball flight and enhance ball speed.

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

Mizuno suggest that the 225 irons are just as effective as a mid-long iron alternative for better players as they are as a a full set for low to mid handicap golfers.

The Pro 225 irons are available in 4-GW with the option of a 2-iron, and are priced at £200 per iron.

Mizuno Pro Fli-Hi Iron

The Fli-Hi is a long iron replacement which is all about providing ball speed, and is designed to be played with a graphite shaft.

It has a longer head length, slightly more offset and a wider sole than the 225 long irons.

It features Mizuno's first ever Maraging MAS1C face in an iron, delivering much higher ball speeds to give you more distance and more power off the tee.

Available in 2-4 iron only, the Fli-Hi is priced at £250.
