Description

The new Mizuno JPX923 Hot Metal Irons are crafted from Chromoly 4335, which is 35% stronger than the Chromoly 4140M used in the previous generation, JPX921 Irons.  Chromoly 4335 is so durable that it’s used in landing gear, transmission gears, and military aircrafts.  This new, extremely tough material allowed Mizuno’s engineers to reduce face thickness by 8%, resulting in the thinnest face in JPX history.  The thinner, hotter face generates explosive ball speeds that toe the boundary of what the USGA legally allows.  Additionally, the previously mentioned speed and distance are available across a much larger area of the face.  The 923’s more prominent sweet spot works harmoniously with the iron’s revolutionary perimeter-weighted design, giving rise to prodigious forgiveness.

• New 4335 Nickel Chromoly is 35% stronger than the original Chromoly allowing for a thinner, faster club face
• New V-Chassis offers more satisfying feel with a fine-tuned vibration pattern
• Seamless cup face construction creates a deep center of gravity for high launch and controllable landings
• Thinnest part of the sole is wider to create a larger high-energy area for consistent speed all across the club face
• White stain non-reflective, Chrome-plated finish reduces glare at address
