Mizuno Pro S-1 Irons: The Technology
While the Mizuno Pro S-1 honours Mizuno’s strong history when it comes to irons, it is by no means stuck in the past. In fact, this model debuts several refined technologies that elevate it beyond a standard muscle back.
Rather than a traditional solid muscle, the S-1 features a Channel Back geometry. This redistributes weight vertically for a more stable centre of gravity, enhancing launch consistency while maintaining workability. The feel is a slightly more solid, tour-preferred sensation., giving precise, confident feedback without compromising on Mizuno’s renowned softness.
