Break Through Your Distance Barrier. When it comes to creating technology-leading fairway woods, Callaway sets the bar. The new FT-iZ Fairway Woods only add to the legacy, with unprecedented distance, stability, consistency and feel in every shot. Polar Weighting Utilizes a heavy face and a heavy in-line power source in the rear, localizing weight at the front and back of the driver to provide stability, consistency, incredible feel and increased linear acceleration of the ball.
