Performance built for female players with moderate swing speeds, these lavishly ultralightweight Woods and Irons are a stately joy to playfeaturing bespoke clubheads and premium, featherweight components. Biflex Face While making the frame even thinner to match the shape of the head, the new BiFlex Face optimizes clubhead stiffness profilesfrom heel to toefor easier distance on center to off-center strikes. Activwing Throughout the swing, aerodynamic forces are generated between ActivWing and the oncoming airflow. These forces help achieve more consistent clubhead delivery at impact, which leads to better downrange performance and distance consistency. Draw-Based Design The Draw-Biased Design utilizes the gear effect to improve distance and directional stability, making the ball more likely to turn back into the fairway and remain in play, even when the face is left open, on off-center strikes, or in wet conditions. 4-Piece Construction w/ Titanium Face 4-Piece Construction With Titanium Face features a remarkably low Center of Gravity combined with the Irons unique Rebound Frame structure for a satisfyingly higher launch with incredible distance and directional stability. Rebound Frame In addition to the L-shaped groove at the bottom of the Iron body, new grooves in the outer periphery of the clubhead improve face rebound for added ball speed and distance. Tungsten-Nickel Weight A 50g tungsten-nickel weight is positioned further to the bottom of the sole than previous models. The lower Center of Gravity provides excellent directional stability and a high trajectory.
