YTEX TRIVOLUTION BLACK

The unique triangle profile, carbon-impregnated string offering great “pop” off the racket face with a truly sensational feel. The bevel-edged design provides a string bed with thin profiles in contact with the ball, which gives the mains and crosses a large surface area of flat edges, creating super durability and virtually no string movement.
This is an exceptional string that will without doubt improve your game.
