The all-new Odyssey 2-Ball SRT Putters feature White Hot XG insert technology and are designed to keep your stroke in line and your putts on target. We refined our high-density zinc alloy Saturn Ring Weighting System to move the weight even farther from the center of gravity, so you get 33% higher MOI for maximum stability and a putting stroke that never wanders. The White Hot XG is the next generation of White Hot Technology. Inspired by proven, high-performance, multi-layer golf ball technology, the White Hot XG is Odyssey's latest advancement that utilizes a multi-layer insert for phenomenal performance on the green. It combines two materials to take the level of feedback, feel and distance control to an all-new, extreme level.
