Tretorn’s micro cell tennis ball, the Tretorn Micro X, is neither pressurized nor pressureless. By utilizing over 700 million balloon-like microcells that don’t 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. The patented leak-proof design means Tretorn Micro X tennis balls remain playable for extremely long periods of time.
Each plastic sleeve contains three Tretorn Micro X balls. Tretorn does not provide air-tight packaging for these balls because they do not lose pressure!
We find that with the extra high bounce they perform well in wet conditions.
Case contains 24 tubes for a total of 6 doz. balls
