Lobster Tretorn Micro X Tennis Balls - Set of 90 Balls

The 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. Each Micro X ball is surfaced with Tretorn's exclusive Flex-FelT, which provides superior playability and wear-resistance.
