TechFlex is A3 Performance’s next-generation swimwear fabric engineered for elite performance and lasting comfort. At its core is XLANCE®, an advanced elastic fiber that delivers a uniquely consistent and supportive fit through its dosed elasticity — enhancing body alignment, movement, and hydrodynamic efficiency in the water.

Unlike traditional stretch materials, XLANCE® maintains its elasticity and shape over time thanks to its exceptional resistance to UV rays, sweat, and oxidative degradation. Even after hundreds of hours in chlorinated pool environments, the fabric retains its physical and performance properties.

Sustainably designed for durability, TechFlex with XLANCE® also eliminates the issue of microfiber shedding and fragmentation, remaining intact even under harsh conditions or prolonged use. The result is a chlorine-proof, long-lasting, and environmentally responsible fabric that supports athletes in achieving peak performance, race after race.
