The common DNA of the HYBRID MK series rubbers combines immense spin potential thanks to the long contact of the ball on the racket, as desired for attacking balls, with a more curved trajectory, a very good ball return for high control and excellent speed reserves. For high-level players who like to play with more power and for whom a surface is never fast enough, we've developed HYBRID MK PRO. With its 51° hard sponge, it can produce much more energy and is the perfect choice for aggressive players.
