Available in 90 ball tub or 2 tone 60 ball tub! A pressureless tennis ball, but one that uses Micro Cellular technology. The Micro X Balls have the best reputation for Coaching or Ball Machine usage. These balls offer great consistency and playability.

The Tretorn Micro Cellular Technology is patented worldwide and is classified in a new category of tennis balls called "micro cell." A conventional ball when hit flattens on the strings and resistance is povided by the compressed air within the ball. Every time the ball is hit small amounts of air escapes. In these Tretorn Micro X balls, the resistance is provided by 700 million air-filled micro cells that cannot escape through the ball's rubber core.

Each Micro X ball is surfaced with Tretorn's exclusive Flex-Felt, which provides superior playability and wear resistance. Flexibility is critical in protecting the soft rubber core.

These bulk tubs are perfect for coaches, clubs, schools and ball machine owners. These X Trainer balls are packaged up and use the same raw materials and technology as the Top of the line Tretorn balls. These balls are the ones that might not have met the extremely tight quality contrls of the Micro X range and are designated as second grade.

Ball Tin Options 4 ball can ($18.95) 3 ball can ($14.95)
