Custom Mizuno Pro Fli-Hi Utility Iron

Tour-Preferred Flight With Modern Speed

The Mizuno Pro Fli-Hi Utility Iron has become a fixture in the bags of Mizuno’s tour players—an easy-launching, powerful long-iron replacement that blends seamlessly into Mizuno Pro sets. Its fully upgraded 4335+ Nickel Chromoly hollow body construction elevates ball speeds while preserving the soft, responsive feel players expect.

A 26-gram internal tungsten weight positioned low in the head boosts launch and forgiveness versus traditional long irons. The offset face weld allows a thinner topline and increased flex low on the face for added speed on strikes that impact the lower portion of the hitting surface. Harmonic Impact Technology is tuned to match the vibration patterns of a classic muscle-back, while increased bounce angle enhances turf interaction for more consistent contact.
