The Mizuno JPX923 Hot Metal Pro Irons are designed for confident ball-strikers seeking maximum ball speed. These irons feature a new material called 4335 Nickel Chromoly, which is 35% stronger than the original Hot Metal material. This enables an 8% thinner clubface, resulting in additional ball speed. The V-Chassis technology delivers a more solid and satisfying vibration pattern, while the deep CG design provides increased stopping power and a high launch with controllable landing angles.

Key Features:

• Faster Nickel Chromoly: The new 4335 Nickel Chromoly material is 35% stronger than the original Chromoly, resulting in an 8% thinner clubface for increased ball speed.
• V-Chassis for more solid feel: Mizuno's V-Chassis technology delivers a more solid and satisfying vibration pattern despite the thinner clubface.
• Increased stopping power: The seamless cup face construction provides a deep center of gravity for high launch and controllable landing angles.
• Consistent ball speed across the face: The sole's thinnest part is extended by 18%, creating a wider high-energy area for consistent ball speeds across the face.
• White-satin brush finish: A non-reflective chrome plated finish reduces bright light glare.
