Introducing Signum Pro Fibercore! Built from an army of flexible fibers, this string is ideal for the player who requires a high degree of comfort. It's also a great option for those who want to reduce the harsh vibrations of lighter, stiffer rackets. Thanks to a special low-friction coating, Fibercore is designed to last longer than the average multifilament. It also has impressive snapback for a non-polyester, which should help you generate more spin. Ultimately, this is the perfect option for those who seek power and comfort.
