Gstar is a blend of Star that adds flexibility and even more grip. GStar is opaque like Star, but features a pearlescent sheen. Their allure is only surpassed by their beautiful flight. GStar discs have a smooth, gradual transition in flight and the same durability as our Star line. For cold weather play the flexibility and grip of GStar cannot be beaten, and even when the weather warms up GStar still retains similar flexibility.
