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, these balls are well suited for play in colder climates, at high altitude and ideal for all court surfaces, including lower bouncing surfaces.
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, solid-yellow Micro X balls, co-branded with the Lobster logo, come in a clear, reusable, string-tied bag for convenient transport to the court.
