Wilson Staff Pi5 Irons
The unique back weighting of the Pi5 design goes from an undercut cavity in the long irons to a standard cavity back in the short irons. This design progressively moves the CG location giving players an arsenal of advantages—from a higher flight with more forgiveness to a lower, more controlled ball flight for maximum shot making capabilities— all with the soft feel of 431 stainless construction. The Pi5 is played on tour by Padraig Harrington and Jesper Parnevik.
