The HDMX string is the string that provides a firm feel with maximum power thanks to its choice of high-end materials. Tecnifibre, the leading brand in strings, is innovating by proposing a brand new version of the hybrid, which generally combines 2 strands of 2 different materials. This new technology combines 3 very complementary materials: Polyester for control and durability Polyamide for power Polyurethane for comfort. This string brings all the benefits of the hybrid in 1 string to facilitate its implementation on the racket. The advanced player will benefit from the best mix of power and control, while maintaining a comfortable feel.

Thermostabyl® Fibres (33%): Generates a lot of control with very good tensile strength. PU HD: 100% elasticity to match the stiffness of the polyester. It will provide extra comfort. S.P.L Coating: Anti-abrasion coating for more resistance. It also guarantees good slipperiness to ensure the "snap back" which provides more lift.
