The Triniti balls are equipped with several technologies in order to not be too stiff at the beginning (compared to most tennis balls within this category), while remaining durable and providing excellent feel. The core has been reworked with a material that is less porous and is lighter than classic rubber in order to better preserve the pressure within the interior of the ball and maintain a similar bounce after several hours of play. The felt has also been modified with more flexible fibres in order to ensure additional grip and enable you to gain control. This revolutionary ball comes in an innovative can and is ideal for very demanding players!
