The iconic HEAD ATP Ball – preferred not only by Andy Murray for its liveliness and ability to reach maximum spin and control – now comes with additional and unrivalled durability. The Flagship of HEAD’s tournament balls with new EncoreTM technology and SmartOpikTM felt for greater visibility. Official Ball of the ATP, many ATP World Tour Tournaments and the Barclays ATP World Tour Finals in London. HEAD’s ATP ball is the official ball of the ATP World Tour and the Masters Series. It is the only ball that is chosen by the players themselves for any Tour event. The ATP’s new Encore™ technology is based on a blend of polymers in a core that limits ball softening. This allows the ball to stay fresh longer and players feel like they are playing with ‘new’ tennis balls for much longer. The ATP ball also has Smart Optik™ felt meaning that they are 20% brighter than standard tennis balls which allows players better reaction time to hit the ball more precisely. The ball is suitable for all court surfaces.
