Go to the limit: The DESTO F1-HS leads the way

Almost all top professionals prefered to play with somewhat harder rubbers. They then used many layers of speed glue to bring the rubber up to full speed and maximum performance. With DONIC DESTO F1-HS, we have adopted a similar principle: we have incorporated a maximum speed-glue effect into a sponge with 50 degree hardness. The built-in speed-glue effect neutralizes the hardness, giving it a softer feel and thereby increasing ball control.

Even though we have increased DESTO F1-HS's speed, it is very spinny and feels like it has a medium-hard sponge rather than a hard sponge!
