Frequently Asked Questions

  • What was the goal behind the development of Triniti?
    On an annual basis, an estimated 400 million tennis balls and 125 million tennis ball cans are purchased and discarded, adding to landfills and other environmental challenges. The goal behind the development of Triniti was to create a more sustainable and durable high-performance tennis ball to empower players with peak performance, while also giving them an option when it comes to environmental impact.
  • In what way is Triniti more sustainable?
    We used an all-new material to create Triniti’s patented Engage Core, which maintains its fresh ball feel 4x longer than a standard rubber tennis ball core*. This new core eliminates the need for pressurized plastic packaging. Triniti comes in a recyclable and biodegradable cardboard sleeve, made with 100% FSC certified materials, thus reducing our contribution to the 125 million tennis ball cans that end up in landfills globally each year.

  • Is Triniti an extra duty or regular duty ball?
    Triniti is an extra duty ball – we have found great performance characteristics on all court surfaces with great durability.
  • Can I use Triniti in a ball machine?
    Yes, Triniti can be used in a ball machine without a problem.
  • Why is there puckering on the felt?
    It was critical to have a felt that lasted as long as Triniti’s patented Engage Core, so we designed a special felt for this special ball. This felt, called STR Felt, is slightly thicker and, as a result, players can occasionally see puckering around the seams. On court performance is not affected and the ball’s durability is incredible as a result of the thicker felt.
  • Is Triniti approved by the USTA and ITF?
    Yes, Triniti is approved by both the USTA and the ITF.
