RS All Court is the first tennis ball ever to be developed by a professional player Robin Söderling. He was once asked – which is the best tennis ball on the market? As he couldn’t answer that question he decided to develop his own. A ball he’s very proud to say is the best he ever used on the court. A ball with no compromises in quality, material, durability or feel. After months and months in labs, high tech production facilities and on tennis courts, Robin Söderling and his product development team is now finally ready to introduce the RS All Court to tennis players worldwide. RS All Court is a ball designed and developed by a true tennis professional, someone who really understands what a ball should feel like. This ball has an amazing feel and great durability.
