A new concept designed to maximize the spin potential of this Co-Polyester string and to control the trajectory of every shot in a perfect way. The triangular shaped main strings increase the friction between the ball and the string bed maximizing the ball bite effect, while the round thin cross strings allow a faster snap back that accelerates the rotation of the ball, adding unique touch and perfect control.
- Length: Cross 6.5m - Main 5.5m (set) , Cross 108m / 356ft - Main 92m / 304ft
- Gauge: Main 1.25mm / 17g - Cross 1.20mm / 18g
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 HawkTM Tour String. It combines highest possible energy efficiency for explosive power with optimized control and touch in every shot.

These strings are great. Really grip the ball & pull it down with great topspin. Fairly durable as well. I play 3-5 times per week & the strings last about 3 months. Overall great string!!
