SPIN IT ANY WAY YOU WANT The Head Hawk Rough Tour Tennis String is the perfect string for high-level versatile players, has a rougher surface that provides more bite and increases the spin on the ball. Thanks to the innovative Crystal Core Technology, a manufacturing process that allows to influence each string’s individual balance between power and control, the HAWK TOUCH monofilament string features a bigger crystalline inner core responsible for providing ultimate touch and control to your game. If versatility is your game’s middle name, this one is the perfect string for you. CRYSTAL CORE - RELEASE THE TENNIS PRO IN YOU This newly developed, innovative process allows HEAD to control the molecular crystal structure within a monofilament string and engineer different material properties in the outer and the core region of the string, setting it apart from conventional monofilament polyester strings. Highly orientated molecules on the outside of the string generate stiffness and energy efficiency releasing more power and explosiveness. Meanwhile, a more crystalline inner core is adding dampening and touch to the string’s performance. By creating unique variations in the molecular structure within the cross-section of monofilament strings, HEAD’s CRYSTAL CORE technology opens the door to a new era of polyester strings with unique combinations of ultimate power and feel. CRYSTAL CORE technology is introduced with the new HEAD Hawk Tour String. It combines the highest possible energy efficiency for explosive power with optimized control and touch in every shot.
