Gamma is famous in the tennis world for their technologically advanced tennis strings. All Gamma strings feature Advanced Gamma Processing Technology. This proprietary technology alters the molecular structure of co-polymer material using high energy Gamma irradiation. Gamma strings are made from premium materials which are bombarded by millions of high energy Gamma rays to create millions of extra bonds between molecules for greater elasticity, resiliency and strength. Aside from strings, Gamma also manufacturers cutting-edge tennis accessories like grips, vibration dampeners and tennis bags. Recently, Gamma introduced a line of high-performance tennis racquets.
