Mizuno JPX 900 Forged Irons

Mizuno JPC 900 Forged Steel

The successor to the JPX 850 Forged, the Mizuno JPX 900 integrates 1025 Boron with the forged steel to produce a stronger, yet thinner face. The updated design offers improvements in both ball speed and forgiveness.

TECH SPECS

Benefits from Boron:

• 1025 Boron is roughly 30% stronger than 1025E, allowing thinner, hotter, more extreme geometry.
• Increased strength of Boron material frees up discretionary weight to be more optimally used.
• Grain Flow Forging process delivers soft, solid, consistent feel.

NEW CORTECH Design:

• Multi-Thickness Face Allows for higher ball speed retention on off center hits
• Oriented to optimizer rebound and ball speeds on center impacts
• Large rebound area combined with COR Tech helps deliver a new level of COR for a forged iron

Reshaped Pocket Cavity:

• Thinnest area of sole extended in both the Toe and Heel directions for more ball speed across the face
• 21.5 grams removed to be redistributed to the Power Frame for forgiveness and stability
