A proprietary extrusion process utilizing blended polymers maximizes the recoil properties while maintaining softness for enhanced control and feel in Alien Black Diamond String. Designed with the elite player in mind, this string is engineered to provide the optimum blend of power, feel, control, and durability.
Other strings can lose their "memory" after being under tension for a period of time creating a "dead" feel and loss of power. While no string will last forever, Alien brand strings undergo a heat and stretching process that extends the life of our strings and provide superior tension stability. Alien strings were engineered to produce very specific playing characteristics that only work with a string diameter of 1.30 mm.
