Double-faced defensive rubber powered by tensor technology Def-Off hybrid weapon. A very special pimples-in rubber developed for modern hybrid/defensive players. TENSOR technology also created new paradigm for hybrid rubbers. Modern hybrid players should effectively combine cut defence and top spin attack. YANUS DF has extremely soft top sheet and sponge to provide extra control advantage. Stability and precision at cut defence are improved far over classic sticky defensive rubbers. On the contrary, the very high level of speed glue effect has been permanently incorporated in YANUS DF to make aggressive top spin attacks. YANUS DF can add the advantage of unexpected topspin attack without a help of speed glue to leverage your defensive game.
