The Sigma 2 putters engineered with a new level of performance features a softer feel created by a dual-durometer face insert. This approach includes advanced putter fitting with a simple and intuitive adjustable-shaft-length technology that is a standard feature of every putter in the line. The dual-durometer PEBAX insert features PING’s patented True Roll face pattern. The softer front layer ensures the precision necessary for shorter, delicate must-makes. The firmer back layer offers the solid feedback and distance control required for holing longer-range putts and improving overall consistency. The Wolverine H putter has an angular shape that combines with ball-shape geometries and a long alignment line to simplify aiming for improved accuracy. To promote consistency, the heavier 370-gram mallet head on this putter provides a very high moment of inertia for extreme forgiveness, especially on shorter putts.
