Description: Ping's new i525 irons are made for enhanced speed, distance and control in a compact, players design. A new ballistic face and perimeter weighting provide high performance and forgiveness. Variable-thickness, maraging steel offers a thinner, more dynamic face with increased flexing for higher launching shots with more speed. The precision-milled Micromax groove pattern allows for tighter spacing and an average of four more grooves in each face to limit fliers in the short irons whil
