Tretorn's micro cellular
technology is patented worldwide and recognized by the
International Tennis Federation (ITF) as the pioneer in
a new category of tennis balls called "micro cell."
Tretorn's micro cell tennis ball, the Micro X, is
neither pressurized nor pressureless. The Micro X ball
combines the best of both worlds, resulting in a tour
performance ball that does not lose bounce or
performance over time.
