Silvergray shuttlecocks are meticulously engineered for distance stability under widely different
environmental conditions of play. Silvergray patent pending HRS retains humidity to improve play.
Using European technology and constant research and development, Silvergray shuttlecocks closely approximate the fast recovery, peak and drop and flight trajectory. In high speed smash tests to 350 kmph, Silvergray
shuttlecocks consistently recovered in 0.015 seconds.
