Polyethyleneterephthalate, produced with extreme viscosity, with strong memory energy is the basic for one of the best strings the tennis world can expect.
Introducing Dyreex Black Edge : a comfortable co-polyester with massive spin potential and surgical targeting on full swings. With its grippy five sided profile, the Black Edge puts a tight grip on the ball, making it easier for the strings to grab and load the ball with spin. Designed with softening agents like polyethylene additives, this string is able to provide much more comfort and power than a standard polyester.
