The International Tennis Federation maintains an approved ball list, and only balls on that list may be used in ITF-sanctioned events. To earn a place, samples are tested for weight, size, deformation and rebound against strict tolerances.

For clubs and academies, choosing ITF-approved balls removes uncertainty: bounce height stays within the 135–147 cm window, and deformation guarantees a consistent, fair feel across every sleeve in the case.

Our match-grade line is produced on the same specifications and submitted for ITF testing each season, so distributors can offer tournament-ready stock with full traceability.
