Head Hawk Touch Black Colored Poly (Co-Poly) Tennis Racquet String Sets - 18 Gauge - Tennis Racquet String Sets 2-Pack (2 Sets Per Order) - Best for Control and Spin

• A SOFTER POLY: Head Hawk Touch Black Colored Poly (Co-Poly) Tennis Racquet String Sets are designed to be on the softer side of poly strings. It has a unique Crystal Core Technology that features a pliable inner core surrounded by a firm polyester shell. This results in a softer poly string that will not cause as many arm issues, yet still has the control, spin, and durability that players are after in a co-poly string. STRING COMPOSITION: Co-Polyester shell with Crystal Core Technology PERFECT HYBRID SETUP: Advanced players and pros alike have been using a hybrid string setup, where (2) half-sets of different types of strings are combined to form a bed with many desired characteristics. An excellent example of this is how a poly string such as Head Hawk Touch can be paired with a softer multifilament. The result is a softer and more lively string bed - with the added durability and spin generation of the poly string - the best of both worlds!
