The DONIC BLUEGRIP J series continues its evolution with a rubber that blends the cutting-edge properties of two elite technologies. Developed under the guidance of world champion Zhang Jike, it combines the BLUESTAR A’s advanced top sheet with the BLUEGRIP C’s proven sponge architecture and pimple geometry. The result: a versatile and high-performing rubber for players who demand speed, spin, and feel.

Three sponge variants are available:
- J-1: Hardest version for explosive precision
- J-2: Medium hardness for balanced offense
- J-3: Softest option with excellent touch

Each version reflects Zhang Jike’s meticulous testing and input, earning the series its “J” badge with distinction.
