Mizuno proudly introduces the highly anticipated Mizuno Pro Irons, including the Mizuno Pro 241, Mizuno Pro 243, Mizuno Pro 245, and Mizuno Pro Fli-Hi. These irons signify a revolutionary leap in golf club design, a testament to Mizuno’s enduring commitment to precision craftsmanship and forging excellence.
The Mizuno Pro Irons are the result of a longstanding connection between Mizuno’s club engineers and the legendary Grain Flow Forging plant in Hiroshima, Japan. This unique relationship has enabled the creation of increasingly intricate designs flawlessly incorporated into the finished equipment. Every fraction of a millimeter and subtle curve has been meticulously considered, shaping the future of golf club technology.
David Llewellyn, Director of R&D at Mizuno, emphasized the significance of this innovation, stating, “Other manufacturers have widely adopted Mizuno’s work to elevate the performance of elite player’s irons. What now sets Mizuno apart is the ability to apply precise manufacturing techniques learned at our long-standing forging plant in Hiroshima, Japan, to increasingly complex designs.”
Chris Voshall, Product Director at Mizuno, remarked, “Everything about the new Mizuno Pro 241/243/245 and Fli-Hi is pushed to the extreme – from technology to more streamlined playing profiles. Each model has become better at its specific job, more distinct, yet able to be blended when required.”
Key Features of the Mizuno Pro 241 / Center Muscle:
● Grain Flow Forged HD in Hiroshima, Japan
● Soft Copper Underlay for enhanced feel
● Center mass for enhanced feedback
● Aggressively tapered blade for an ideal trajectory
● Thinner, tour preferred topline
● More compact short irons
● Increased bounce angle for improved turf interaction
● Full Satin Brush finish
● Available 3-PW / RH and 4-PW /LH
David Llewellyn noted, “With a muscle-back, the gains are in the details. The key to a visually appealing top-line might be a fraction of a millimeter, which can be lost or created in manufacturing. Working hand in hand with our forging plant for so many years allowed us to be incredibly precise in the engineering and craftsman’s stages of the Mizuno Pro 241.”
Chris Voshall added, “The muscle-back has re-established itself as Mizuno’s most played model on tour over the last couple of seasons, so we gave our professional ambassadors a more involved role in the development of the Mizuno Pro 241. You can see their influence most in the narrower top-line and compact scoring irons.”
Key Features of the Mizuno Pro 243 / Tour Speed:
● Grain Flow Forged HD in Hiroshima, Japan
● 4120 Chromoly with Flow Microslot (4-7 iron)
● Soft Copper Underlay for sensational feel
● Harmonic Impact Technology for a soft muscle-back feel
● Wrap Around Sole Grind for improved turf interaction
● Exceptionally compact players’ profile
● Increased bounce angle for enhanced performance
● Full Satin Brush finish
● Available 4-GW / RH only
David Llewellyn explained, “The Mizuno Pro 243 is the model that’s advanced the most, mainly due to evolution on the manufacturing side. It’s one thing for the R&D team to design a thinner face iron with stronger materials in the CAD world – but something else to have it Grain Flow Forged to those specifications and strength requirements.”
Chris Voshall noted, “The Mizuno Pro 243 looks much more compact than its predecessor, even though the performance has stepped up. The long and mid irons are flying far enough that we’ve had to modernize the lofts in the scoring irons. Mizuno Pro isn’t stuck in tradition – we’re led by performance above what might be expected historically.”
Key Features of the Mizuno Pro 245 / Tour Speed and Launch:
● Grain Flow Forged HD in Hiroshima, Japan
● Hollow body GFF 4135 Chromoly face and neck (2-8 iron)
● Internal Tungsten Weighting (2-7) for improved launch
● More compact partial hollow scoring irons (9-GW)
● Soft Copper Underlay for exceptional feel
● Harmonic Impact Technology for a soft muscle-back feel
● Traditional blade appearance
● Increased bounce angle for optimal turf interaction
● Full Satin Brush finish
● Available 2-GW / RH and 4-GW LH
David Llewellyn noted, “There’s so much to the Mizuno Pro 245 for an iron of its size and shape. A multi-piece Grain Flow Forged Chromoly construction, suspended Tungsten weight, and multi-thickness face. Impossible without Mizuno evolving its Grain Flow Forging process in Hiroshima.”
Chris Voshall commented, “There are some impressive ball speed gains in the Mizuno Pro 245, considering we’ve slimmed it down – especially in the longer irons. The biggest challenge for people now is telling this iron apart from the one-piece Mizuno Pro 241 muscle-back.”
Key Features of the Mizuno Pro Fli-Hi / Tour Long Iron:
● Nickel Chromoly 4335 Hollow Body Construction
● Internal Tungsten Weighting for elevated launch
● Harmonic Impact Technology is applied to best match the vibration patterns
● Increased bounce angle for improved turf interaction.
● Offset face weld for greater shot shape adjustability
● Black Ion Finish for a modern appearance
● Available 2, 3 & 4 iron / RH and LH
David Llewellyn highlighted, “Hybrid type irons generally use a flat sheet metal for the face – but upgrading to a heat-treated 4335 Nickel Chromoloy allowed us to incorporate a faster multi-thickness face and off-set face weld.”
Chris Voshall added, “The Fli-Hi has become a fixture on tour – not just with Mizuno’s contracted players. The new version is a little slimmer but does everything the original did, just better. It flights a little higher and goes further. All obvious improvements – just difficult to make.”
