Tretorn Micro X 72 Ball Bag Water Bottle The use of fibres insteadTretorns micro cell tennis ball, the Tretorn Micro X, is neither pressurized nor pressureless. By utilizing over 700 million balloon like microcells that dont lose pressure, 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. Because Tretorn Micro X balls do not rely on gas pressure to maintain their bounce, the aspect of the balls going flat is completely removed.
