Spider S is built with premium materials to deliver exceptional performance and optimal stability. Heavy tungsten is placed in a back weight bar to create the deepest CG in a Spider putter to date. A White TPU Pure Roll insert encourages optimal roll with enhanced sound, feel and performance characteristics. The new white "arrow" design on the top, front face allows for golfers to easily align and center the ball at address. Spider S obtains high MOI through the use of advanced geometry and multi-material construction – giving you enhanced forgiveness and an efficient transfer of energy from the putter face to the golf ball.
