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 while preserving spin in the longer irons. These players irons combine new performance designs with a polymer construction that improves feel for an iron that plays as beautiful as it sounds.
