Tretorn Micro-X tennis balls are recognized worldwide as the superior choice of ball for tennis ball machines.
With patented technology, Tretorn Micro X tennis balls are the original high-performance micro cell ball — powered by 700 million air-filled micro cells for improved playability. The exclusive high visibility flex-felt provides the best core dynamics and durability. Due to its construction, the Tretorn Micro X ball is well suited for play in colder climates, at high altitude and ideal for all court surfaces, including lower bouncing surfaces.
The yellow/white balls are ideal for training and development of spin control. The two-tone ball allows for greater vision of topspin and backspin. The yellow/white balls are also great for identifying your balls on public tennis courts.
Lobster Sports highly recommends the use of Tretorn’s Micro X tennis balls since standard tennis balls become soft and lose their pressure quickly. Neither pressurized nor pressureless, the Micro X balls simulate the performance of pressurized balls while keeping the lifetime of pressureless balls.
The 72, yellow/white Micro X balls come in a clear, reusable, string-tied bag for convenient transport to the court.
