These irons feature a 360º Deep Undercut Cavity: The deep channel at the sole promotes stability at impact and forgiveness on off-center hits.
The undercut cavity expands the unsupported face area for more ball speed across the face. It also removes weight from the topline to create an ultra-low Center of Gravity.
New lower Center of Gravity placement promotes a high launching, strong and penetrating ball flight. As the center of gravity moves lower on the ball, it promotes a higher ball launch.
These irons feature a game improvement design for a wide range of golfers seeking more distance through a high launching trajectory.
