PXGs Battle Ready II Putters feature a thin-walled hollow body construction, injection molded core, and the thinnest face in putters. The result is a high moment of inertia (MOI) design, coupled with a remarkable sound and feel on every stroke. The One & Done is a mallet-style putter with newly updated prominent alignment aids to promote a more confidence-inspiring stroke on the greens. The ultra-deep center of gravity and adjustable sole weights optimize MOI and ensure stability and consistency with every putt.
