The Lynx 2010 Ladies HXI Iron Set features three hybrids that replace the 4-, 5- and 6-irons. This set comes with five deep-cavity irons, including 7, 8, 9, PW and SW. The Hybrids are designed with tungsten-infused polymer weight that along with the general design of the head move the weight to the rear of the club, enhancing the dynamic loft and making it easier to hit high and soft-landing shots. The deep cavity irons create a low center of gravity and very wide sole for optimal performance. These irons also include a polymer insert to optimze the feel.
