Gear: Mizuno ST-Max 230 hybrids
Price: $250 with Mitsubishi Lai’ Li Blue, UST-Mamiya LIN-Q Blue Hybrid or Helium NanoCore Hybrid shaft and Lamkin ST Hybrid grip
Specs: MAS1C maraging stainless steel with stainless steel chassis with an adjustable hosel. 19, 22, 25 and 28-degree head options.
Who It’s For: Golfers who want an easy-to-hit replacement for their long irons that produces a high launch angle and extra carry distance.
The Skinny: The new ST-Max 230 hybrids are like miniature fairway woods, with a larger size and high moment of inertia (MOI) to make them easy to hit off the tee and from the fairway for golfers who want more forgiveness and distance than traditional long irons.
The Deep Dive: The new Mizuno ST-Max hybrids are designed to appeal to the same golfers who will benefit from the ST-Max driver and fairway woods, meaning golfers who want to maximize stability and forgiveness.
While the driver and fairway woods utilize multi-material constructions, the hybrids are all stainless steel. Instead of adding a small carbon fiber crown, Mizuno made the top of the club thicker in some areas and thinner in others. The brand refers to it as a Waffle Crown, and while the glossy black top gives the ST-Max hybrids a classic look in the address position, it reduces weight on the top of the head.

To increase ball speed, a larger CorTech Chamber complements the MAS1C stainless steel face in the sole. It’s a slot designed behind the leading edge that is then filled with a blue thermoplastic polyurethane (TPU), so grass and debris do not get inside the head. Inside the TPU, Mizuno designers have added a stainless steel bar that helps the head maintain forward momentum at the moment of impact. So, while the TPU reduces weight and soaks up excessive vibrations, the CorTech Chamber also helps golfers generate more ball speed.
The larger size, from heel to toe and from front to back, makes the ST-Max 230 hybrids more stable on off-center hits, but the addition of a weight in the back of the sole helps to drive up the MOI and further increase stability.
To help golfers and fitters fill distance gaps and provide clubs that go to precise distances, the ST-Max 230 hybrids are available in four loft options. However, each club’s adjustable hosel allows the stated loft to be increased or decreased by up to 2 degrees. The result is golfers can adjust the clubs to cover lofts from as little as 17 degrees to as much as 30 degrees.
