The Callaway Odyssey White Hot XG Marxman putters are the latest in revolutionary alignment design from Odyssey. With their Hi-Def Alignment System, these putters offer every possible advantage so more putts start on the intended target line. A high level of mass positioned low and deep in the head is centred on the target line, promoting solid feel and true roll for putts that track to the hole. And with our softest, most responsive insert in the White Hot XG, these putters are the per fect addition to a tour-proven alignment line-up that already includes 2-Ball and Tri-Ball® technologies. Inspired by high-performance, multi-layer golf ball technology, the White Hot XG Marxman insert takes two materials with different properties and combines them to take the level of feedback, feel and distance control to an all-new high. Elastomer core material is soft for enhanced feel, and highly resilient to get the ball rolling. Thin outer striking surface with urethane is firmer for fine-tuned responsiveness.
