ProtoConcept C05 Golf Irons

Distance, precision, unrelenting power, forgiveness, and feel - this tour pocket cavity iron has it all! It's the perfect combination to satisfy a range of expectations.

SAE8655 Chrome Molybdenum Steel is Used in the Proprietary Structuring with Thickness Deviation.

SAE8655 chrome molybdenum steel, tougher than soft iron, is employed on the face for additional weight and to create a deeper, lower center of gravity for an easy ball lift and a straight ball flight. The face's overall thickness is set at 2.7mm, delivering the feeling of a single forged cavity iron; meanwhile, the center left and right areas are thinned to 2.4mm to maximize distance while still maintaining the feel at impact.

Optimised Center of Gravity Design that Delivers Performance Needed for Irons

Enhanced mis-hit forgiveness and a straight trajectory, all without sacrificing face size, are achieved through pocket cavity structuring and a clubface designed with precision thickness deviations. The C05 offers a sleek aesthetic and incredible maneuverability, heightened controllability and strong shot-making from any lie – perfect for pros and skilled players.
