Tecnifibre's HDMX Tennis String was developed for the larger group of tennis players that find themselves in between multifilament and polyester strings. With Hybrid 3D technology, HDMX incorporates a blend of polyeurethane for comfort, polyester for control, and polyamide fibers for power.


The concept is to blend the comfort and forgiveness of a multifilament with the control and durability of a polyester. The string has Tecnifibre's SPL anti-abrasion treatment to enhance durability. HDMX represents a great "first step" when leaving the world of multifilament strings in search for better durability and precision, while maintaining comfort.
