Tecnifibre Triax

Triax was developed for players who crave control without the stiffness of a polyester string. It is constructed of 50% polyurethane and 50% TPI (Thermo Polyester Improved). According to lab results, Triax offers a 15% firmer stringbed when compared to a typical multifilament and a 50% increase in durability. If you love polyester firmness and control, but have struggled with arm or elbow pain, Triax is the string to try.
