The PING i25 8pc. Iron Set with Graphite feature Tungsten Weighting low in the toe for enhanced forgiveness on off-center hits. Dual Stabilizing Bars are narrow in the long irons for faster speeds, longer distance, and higher launches. The bars are wider in the short irons for lower launches and better control from all over the course. Lower positioning of the CTP brings better feel and control of trajectory allowing you to find more greens and fairways throughout the round.
