Product Overview: Elite Players Cavity Everything tour players need to compete on extended, more demanding layouts - but never thought to ask for. The Mizuno Pro 223 conceals a ball speed-enhancing construction within the frame of a compact players cavity. A completely new technology platform from 4-7 iron combining Mizuno's tested Chromoly Forging and Flow Micro-Slot Grain Flow Forged in Hiroshima Japan with a soft copper underlay and uniquely satisfying Mizuno sensation at impact. Features: FORGED IN HIROSHIMA JAPAN One-piece Grain Flow Forged HD at Mizuno's iconic facility in Hiroshima, Japan – where Mizuno irons have been produced since 1968. SOFT COPPER UNDERLAY A microlayer of copper beneath Nickel Chrome – for the purest, softest feel made famous in the legendary TN87. Reintroduced in 2018. FORGED CHROMOLY WITH FLOW MICROSLOT (4-7 IRON) A completely new technology for extreme ball speeds from a small tour-ready profile - delivers a face thickness of just 2.4mm (vs 2.6mm JPX921 Forged). 1025E PURE SELECT MILD CARBON STEEL 8-PW For ultimate precision and control where it's most needed – the same construction as the Mizuno Pro 221. BUILT FOR DISTANCE. SIZED FOR TOUR The Mizuno Pro 223 was sized to get into the hands of tour players – where looks are the first barrier. The Mizuno Pro 223 is smaller than its predecessor, the MP-20 MMC – most noticeably in the scoring irons. PRECISELY BEVELLED BACK EDGE To accommodate the micro slot but still provide an authentic tour accepted sole – the back edge is heavily bevelled.
