The Ping G15 Irons replace the hugely popular, market leading G10 irons and introduce a number of improvements that make them even more attractive than their best selling predecessors. The biggest improvement is that the G15 irons are a bit more forgiving thanks to the moment of inertia increasing which Ping has achieved by introducing a custom tuning port that is further back from the face of the clubhead. This has allowed Ping's designers to remove seven grams from the G15’s face custom tuning port structure without destabilizing the clubface or reducing distance control. This weight is repositioned to move the center of gravity lower and back in the club head to help provide high launch and optimal spin. The G15 also have a slightly thinner face design with more weight moved to the toe to help increase forgiveness and the lofts are stronger and the sole design slightly wider than on the G10 irons to help produce strong and high trajectory. The Ping G15 irons also have a full cavity graphics badge which helps to improve the feel of the club and promote a much softer feel.
