Mizuno�s JPX Fli-Hi�s are precision hybrids � engineered to directly replace your least reliable long or mid irons. The new Fli-Hi�s wider footprint and material construction deliver an even more playable, high flying alternative than their predecessors. A 17-4 stainless steel face and 431 body delivers an upgrade in ball speed � while maintaining a bendable hosel that allows for adjustments in lie angle.
