Revolutionary SPEEDBACK shaping adds more mass lower and wider than a traditional iron to substantially increase stability, MOI and forgiveness. A new Carbon Topline is constructed with light fiber inserts that create a lower CG and explosive ball speed. PWRSHELL Technology expands the SWEET ZONE and increases flex at impact for improved performance across the face.
