ProtoConcept C07 Golf Irons


ProtoConcept C07 Golf Irons

Distance, maneuverability, straight-shot prowess, forgiveness, and feel -- all embodied in this tour-pocket-cavity iron, delivering an unparalleled experience!

SAE86555 Chrome Molybdenum Steel Used for the Face with Three Level Thickness Deviation

Made from tougher SAE8655 chrome molybdenum steel, the face of Proto-Concept C07 Irons not only has an excess weight to lower its center of gravity, but also features a 3-level thickness deviation with three unique phases. To enhance the feel and sound of face-welded irons, the lower face is made thicker to 2.7mm and the top blade thinner, so players with slower swing speeds get a great ball retention. To maintain strength with its 1.8mm thinness, only the upper part of the face is heat-treated with high-frequency. This results in a ball rising easily and soaring straightly!

Engineered with Optimal Weight Placement in Pursuit of Results

The bold pocket and face structure with thickness deviation results in a low and deep CG, offering mis-hit forgiveness and a straight ball flight. Featuring an orthodox shape, ease of addressing and swinging, our proprietary 3-level thickness deviation on the face, and the soft S20C body, PROTOCONCEPT provides high bounce, solid feel and improved ball retention.
