Proto Concept C07 Custom Irons

Pocket cavity iron with satisfying feel that prioritizes distance and softness.

SAE8655 with remarkable toughness is used for the face. While increasing the initial velocity of the ball with high bounce, the excess weight created is used to maximize forgiveness and straight ball flight.

The face is designed to be thinner towards the top with proprietary thickness deviation, and the body is made of soft S20C material to achieve high bounce and solid feel. This is a highly stable model for golfers who prioritize distance performance and results with low loft.

With SAE8655 chrome molybdenum steel, the face is made thinner and high bounce is created by using SAE8655 tougher than soft iron for the face material.
