HEXER Duro is designed for all players who demand from their rubber strong spin and speed characteristics combined with very good durability. The 100% natural caoutchouc upper layer and the medium-hard sponge in HEXER technology give access to a very broad range of strokes: the sticky upper layer provides a prolonged ball contact time – thus the player leads the ball longer and experiences more control during passive as well as during active strokes. The highly developed endurance enables a later change of rubbers which is comfortable and economic. This has made the HEXER Duro earn the rating LONGLASTING PERFORMANCE.
