Sieger = Winner / Victor / Champion in German.

The Sieger PK50 rubber impresses with its “S-Touch” topsheet, which enables a high ball arc.
The sticky topsheet allows you to attack, even when you have lost your balance or timing.
Whether you’re attacking, playing aggressive push strokes or the banana flick, you’re sure to be the victor!

Made in Germany.
