This is the exact ball used in several ATP Tour Events (Rotterdam, Marseille and Gstaadt)
The X-One has the highest percentage of natural felt of any ball on the market (72%) making it ideal for long sessions both clay and hard surfaces
Grand Prix formula rubber used (jointly manufactured with Bridgestone) makes the ball more durable with longer true bounces
Four balls in a can! Less chasing balls between points.
These balls will truly last an entire three set match between two UTR 13+ level players (USTA 5.5+). They will last 2-3 matches for lower level players.
