Isospeed Energetic Plus String Reel 200m 1/045407

The surface of the Energetic Plus model consists of heat-sealed, highly elastic Power Ribbons. The multifilament (consisting of several fibers) core forms a pre-stretched polyamide braided cord that, at the slightest loss of tension, lends the string enough resilience that it offers high control over the ball. Its extravagant composition provides for more top spin. Materials Surface: polypropylene, heat-sealed power ribbons Core: polyamide, polyester Pre-stretching: core Technologies Power Ribbons: Power Ribbons are wound several layers thick so that they overlap and are diametrically opposed, thereby simulating the structure of a natural gut string. Pre-stretched: Pre-stretching the string core reduces the loss of tension to a minimum. Braided core: due to its exceptional structure, it gives the string uniform elasticity and high resilience.
