The G2i putter Series combines the performance of perimeter weighting with the soft feel of a proprietary insert material known as Polypurfelan. The urethane-based material produces a softer insert that creates a pleasing feel and sound. Additional perfomance comes from the increased perimeter weighting and lower center of gravity achieved through redistribution of the mass removed to create the insert cavity. The insert cavity and face are precision milled for quality and consistency, creating a flat surface for accuracy on the greens. With the clean, square lines inherited from the G2 Putters Series, the G2i models have improved optics and exceptional feel.
