Mizuno gives easy power a facelift with the new Pro Fli-Hi driving iron

While Mizuno's extensive roster of staff players tend to favour an eclectic mix of the Japanese brand's clubs, there's one model on which most of them seem united: the Pro Fli-Hi driving iron.

Pound-for-pound, the Pro Fli-Hi has for a long time been perhaps the brand's most popular single club on tour. In addition to the manufacturer's contracted roster, Wyndham Clark, Luke Donald and Cam Smith are just a few players to maintain one of the much-loved long irons in their bag.

How, then, do you improve on an already beloved formula? That's the mission of the new Pro Fli-Hi, launched today alongside the new Pro M-13 and M-15 irons with the start of the 2026 season rapidly approaching.

The Pro Hi-Fli is designed to sit spiritually (and, from a gapping perspective, practically) alongside these two new models, offering a forgiving, easy-launching long option for players who prefer a traditional driving iron to a hybrid or fairway wood. Rendered in a smart dark oil can finish that Mizuno calls Black Ion Satin, it sits distinctly apart from the clean nickel finish of the manufacturer's forged irons, equal parts imposing and reassuring.

The Pro Fli-Hi has long distinguished itself from other driving irons for its emphasis on launch, forgiveness and feel: all characteristics the brand has sought to improve further with the 2026 update. 

Ranging from a 2 to a 4 iron in loft, the new Pro Fli-Hi receives a heavier tungsten weight that sits just below the bottom of the face, lowering the centre of gravity, moving the sweet spot lower on the face, and increasing launch.

The chassis, meanwhile, has been cast (note: not forged, interestingly) entirely from 4335+ Nickel Chromoly for the first time, which is softer, more flexible and malleable. This, in combination with the new iron's 39% thinner face, optimises feel while increasing ball speeds.

The power boost hasn't come at the cost of playability, however, and Mizuno have taken added steps to ensure the new Pro Fli-Hi doesn't lose its emphasis on forgiveness. Mizuno have placed the weld line is back from the face, allowing greater flex and ball speeds on lower strikes, while they've also added bounce to the sole to aid turf interaction.

Priced at RRP £275, the new Mizuno Pro Fli-Hi driving irons will be available to pre-order from January 19, with an on-sale date of February 5.
