Mizuno Pro Fli-Hi Irons 2024 Specs & Design

The first generation of the Fli-His make history as the first ever Mizuno irons to be made from a Maraging MAS1C steel face and that is retained in the new 2024 version.

Having been a huge success, including in the bag of Cameron Smith, the new version has been made more compact to fit seamlessly into a setup with any of the other Pro series models.

The driving irons have a new L-Face structure in the latest design to increase the rebound of the face and deliver increased ball speeds compared to the 2022 version.

Mizuno have also reengineered the Advanced Core Tech Face, making it thicker in the center and thinner at the perimeter for better weighting.

The overall design of those two technologies means the CNC milled face flexes more than the Fli-Hi 2022 irons and as a result generate better ball speeds.

Feel and sound have also been made better with improved Harmonic Impact Technology for an overall impressive ball strike.

Available in 2-iron (17 degrees), 3-iron (19 degrees) or 4-iron (21.5 degrees), the Fli-His are fully blacked out using Blackout Cosmetic+ treatment in the new version.

Mizuno Pro Fli-Hi Irons 2024 Review: Are they any good?

The Fli-Hi driving irons were a huge hit when first released in 2022 and the 2024 model adds even more performance gains.

The weighting has been improved for more consistent ball striking and some added forgiveness, while the face now flexes more than the previous version.

The more compact clubhead makes the new Fli-Hi irons a better fit at the top end of the back regardless of whether you game the 241, 243 or 245 irons, and we are very impressed with the improvements.
