Designed from the ground up using state-of-the-art technologies and materials, our pressurized and wearable pressurized tennis balls survived durability testing with flying colors. Advanced military-grade glass and carbon fibers were used in the hot and cold press technique. Quality Control is covering all ground from the raw materials to the final testing in order to minimize the chances of issues further along in the line. Because of this our pressurized balls have survived and continue to survive high levels of pressure and extreme wear without any loss of pressure which guarantees consistency in extremely intense games. Other balls cannot withstand the wear and loss pressure. There is no doubt. Our wear and performance determined the expectations our product was built for, and our technology even for the toughest of professional sports organizations was built to exceed the expectations suited for the product to be used in official tournaments.
