Triniti pushes the limits of sustainable performance. The ball core integrates a unique plastomer material that impressively extends fresh ball feel, while STR Felt provides enhanced durability and is 50% more flexible than the standard ball for better feel at contact. This blend of new core material and flexible felt allows this ball to maintain enough liveliness to exist outside of a pressurized can. Between a combination of innovative ball technology and unique sustainable packaging, Triniti ushers in a new era for performance tennis balls both on and off the court.
