The Donic Blue Grip S combines a sticky surface with a rather soft sponge with a pronounced catapulting effect. It is suitable for players who like sticky rubbers but want something closer to traditional European rubbers. The sponge is considerably softer than in the Bluegrip C series, which makes it easier to play with. The BlueGrip S2 is equipped with a sponge that is a bit softer than the BlueGrip S1, which gives additional control and a softer feeling.
