The PING G15 Iron Set features a new Custom Tuning Port which expands perimeter weighting and increases the moment of inertia (MOI). The thinner face of the G15 Iron helps position the weight to the toe for added forgiveness. Also, the wider sole on this iron provides a higher launch angle for increased carry. The strong lofts and a low center of gravity produce long shots with a high trajectory and maximum forgiveness. These Ping G15 irons are ideal for all golfers, no matter what handicap, looking for increased forgiveness and distance with a set of irons.
