The technology of the G15 iron provides the high-launching, maximum forgiveness benefits that the majority of golfers rely on to bring consistency to their iron play. The stainless steel iron’s cavity design features a new Custom Tuning Port (CTP) which expands the perimeter weighting and increases the moment of inertia. Weight savings from a thinner face are repositioned to the toe for added forgiveness on mis-hits and its wider sole produces a higher launch angle. Stronger lofts combine with a center of gravity located low and farther from the face to produce longer shots without sacrificing the higher launch angle required in a maximum forgiveness iron. TFC 149i Shafts - Designed by PING this premium graphite shaft is engeneered with lightweight materials and features progressive weight, flex and torque profiles to increase club head speed for maximum distance while providing optimal launch conditions for superior control, consistency and feel. Custom Tuning Port (CTP) - A reshaped and repositioned CTP saves seven grams which is allocated to the perimeter to increase the momemt of inertia. Distance Control and Solid Feel - The new design also provides the proper structure and support behind a thinner face to ensure consistent distance control and a solid feel. Wide sole for low CG - A wide sole positions the center of gravity lower and further back to increase the launch angle for higher flying, longer carrying shots. The sole geometry is designed to ensure a smooth transition through the turf. Maximum Forgiveness Available irons: 3 through 9, PW(45°), UW(50°), SW(54°), LW(58°)
