Callaway X Fairway 08 Fairway Wood Modified X-Sole Design - The Modified X-Sole Design provides versatile turf interaction, cutting through thick rough or gliding smoothly over tight fairways. It also lowers the leading edge to help get the ball in the air more efficiently. New head shape - The slightly larger head shape raises the Moment of Inertia (MOI) and is designed to appeal to a wider range of players. The slightly deeper face increases the effective hitting area and provides confidence at address. Increased Perimeter Weighting - Strategically positioned internal weighting provides a high MOI for superior stability on miss-hits and also optimizes ball flight trajectories from the fairway or the tee. Callaway Golf Core Technologies - VFT Technology maximizes ball speed and perimeter weighting for more distance and forgiveness; S2H2 increases discretionary weight by removing it from the hosel and repositioning it in the perimeter of the clubhead.
