What Mizuno Says:
A long iron replacement with a priority on ball speed – the Mizuno Pro Fli-Hi is designed to be played with a Hybrid shaft. Relieved of the constraints needed to flow through a complete set, the Mizuno Pro Fli-Hi has a longer head length, a little extra offset and a wider sole than the Mizuno Pro 225 long irons. With Mizuno's 1st ever Maraging MAS1C face in an iron – for vastly increased ball speeds.

Features & benefits:

• 1st MAS1C Steel Face in An Iron - For the first time ever, we used the high ball speed face material generally reserved for our fairway woods in a Mizuno iron.
• Complex construction - For a high, stable fight, Mizuno combined a bendable 431SS body, MAS1C face and 21g Tungsten weight – dedicated to producing a consistent,
  reliable flight.
• HIT for sound - With such a complex construction, Mizuno's modelling of vibration (Harmonic Impact Technology) was vital in designing a satisfying sound from the
  conception.
• Blackout/Lights out - Turn the lights out on the competition with a fully blacked out ION plating.
