Spider X revolutionizes the way we achieve optimal stability and alignment by reengineering the mass properties of the head and introducing a new optically engineered True Path alignment system. Spider X combines a heavy (320g) steel frame with a lightweight (15g) carbon composite sole to provide extreme perimeter weighting in a more streamlined shape. TaylorMade's new True Path alignment has been optically engineered to help golfers visualize the intended target line for improved putting accuracy. Thicker Pure Roll insert produces better sound & feel while 45* grooves increase topspin to help the ball start and stay on its intended line. Satisfaction and authenticity are guaranteed. Standard TaylorMade warranty applies.
