(Hierros del #4 al #PW)

Y-TUNE Pro

A reduced offset, more compact alternative to the award winning MX-200.

The MX-300 was designed for players looking for the assistance of Mizuno’s undercut cavity design and solid Grain Flow Forged feel – without the shotmaking constraints of normal cavity offset and sole width.

With address dimensions (top line, sole width, face size) falling squarely between the MP-52 and MX-200, and offset closer to MP characteristics , the new MX-300 offers a more solid feel and greater workability than any other iron in the MX line.

The full cavity utilized in the MX-300 irons also contains a reconfigured Y-TUNE Pro technology for enhanced feel and flight control. The milled pocket cavity (3-7) redistributes 12 grams of weight low and deep to provide a high penetrating launch, while the scoring irons (8-PW) utilize a solid power bar design for greater workability.

The sole of the MX-300 irons is dual cambered to minimize turf drag and digging through impact.

This model is designed to conform to the 2010 Condition of Competition rule.


"The MX-300 will be great for solid ball strikers who are accustomed to the forgiveness of a cavity, but want a step up in feel and shotmaking...".
"For good ball strikers, offset often does the opposite of its intended effect – keeping the ball low, rather than generating a higher flight. It also puts the COG way back from the shaft axis, meaning the club takes a bit too much control over where the balls heads.".
"The MX-300's short compact profile and re-configured Y-TUNE Pro gives an MP level feel in a head that will be popular on tour, but will still work for lots of amateur players – especially if their set make up includes the MX Fli-Hi in place of the longer irons.".
