Mizuno MX 900 Irons

The Mizuno MX 900 Irons. The MX-900 seamlessly blends every available Mizuno forged iron technology into one progressive set. Hollow long irons based on the Mizuno Fli-Hi - short forged irons as compact and solid as the MX-23. An equal transition from iron to iron, of distance, feel and workability. Long to mid irons (3-7) are hollow forged from high strength 4135 steel. Progressive Tungsten sole weights create Mizuno's first H.E.M.I technology (High Energy Mass Impact) iron design for an easy launch and maximum forgiveness.
