Ping's K15 irons are still in many pros' bag now
The larger K15 iron combines a lightweight titanium face with a stainless-steel body to increase both forgiveness and launch conditions. Four hybrid options (3 through 6) rely on a patent-pending design that creates lower-spinning, higher-launching shots that fly straighter and longer.
By utilizing a lightweight titanium face, PING engineers made the iron club face larger and added 27 grams to the perimeter for a higher MOI. The iron’s extra-wide sole features a low and deep center of gravity to promote high trajectories and low spin. High launch angles allowed iron lofts to be strengthened without compromising control. A large internal weight pad in the hybrids produces a high MOI for added forgiveness.
