The new Mizuno MX 200 irons with Y-tune technology are a quantum leap in game improvement design. Y-tune technology extends and expands the sweet area of the clubface out toward the toe to deliver amazing forgiveness on mis-hits. With the re-engineered external power bar and inner Y-shape cavity pad, the MX 200s are tuned for unbelievable forgiveness, great trajectory and amazing, forged feel. Further enhancing the forgiveness is a larger clubhead and the super deep milled pocket that creates a lower, deeper center of gravity.
