The sleek new Hawk Eye VFT Irons feature a blend of Callaway Golf's patented science - Variable Face Thickness Technology, 360° Undercut Channel, and Tungsten Weight Matrix. This combination gives you an extra-low center of gravity that helps launch the ball with less effort from just about any lie. These uniquely balanced irons incorporate more advanced technology than ever, with increased forgiveness, especially on those occasional miss-hits. They're fitted with our new "ascending mass" graphite shafts for superior feel, control and trajectory. These new Hawk Eye VFT Irons are gorgeous, but they are really designed to make you look good.
