Odyssey White Hot XG 2-Ball Blade Putter Multi-layer insert technology for the softest, most responsive putter we've ever created. The Odyssey White Hot XG utilizes a multi-layer insert for phenomenal performance with any golf ball. Inspired by high-performance, multi-layer golf ball technology, the White Hot XG insert takes two materials with different properties and combines them to take the level of feedback and feel to an all-new high. Features: Multi-Layer Insert The elastomer core material is soft for enhanced feel, and highly resilient to get the ball rolling The thin outer striking surface with urethane is firmer for fine-tuned responsiveness Allows weight to be shifted to the perimeter of the putterhead for a high moment of inertia, better forgiveness and a truer roll Textured Impact Zone Enhances feel and clearly defines the optimum impact area
