Introducing Triax! With its multifilament construction, this string does not skimp on comfort. What separates this very arm-friendly string from the competition is thatit also hashigher levels of control, making it suitable to bigger hitters. Tecnifibre achieves this control partly through an innovative construction that integrates firm polyester filaments with softer polyamide (nylon) filaments. Triax also gives you the benefit a Silicon Pyrogene Lubritec (SPL) coating, a feature that not only helps it snap back for extra spin but also gives it some protection against the frictional wear that leads to breakage.On the court, our team found it to play firmer and crisper than a typical multifilament but it still managed to deliver arm-friendly comfort with impressive pocketing. You'll also appreciate the fact that it does not require constant straightening (like the majority of traditional multifilaments). In addition to being a solid option for the multifilament player who wants more control, spin-potential and durability, Triax will also tempt the big hitting poly player who wants a more tendon-friendly option.
