Ping i59 Irons

I59 4-pw Stl Proj X Ls Irns [Size: 4-PW]

AlumiCore Technology

An aerospace-grade aluminum insert allows approximately 30 grams of material from the center of the club to be redistributed to the perimeter in the form of toe and shaft tip weights, elevating the MOI to match that of the larger PING i210 iron.
MicroMax Milled Grooves

The precision-machined face has new MicroMax grooves for tighter spacing and a geometry that results in an average of four extra grooves to reduce fliers in the short irons and preserve spin in the long irons.
Tour-Preferred Styling

A thin topline and proper offset presents the clean, streamlined look preferred by skilled players. The hydropearl 2.0 finish repels water to ensure predictable, consistent performance from wet and dry conditions.
Higher MOI

Toe and tip weighting elevate MOI to reduce the stat area and achieve a level of forgiveness unprecedented in a forged design.
100% Inspected Manufacturing Steps

During development of the iron, PING’s innovation and engineering teams spent significant time perfecting the manufacturing process, which includes 100% inspection of numerous steps, including sole shaping, head polishing, face machining and head forging.
