Men's jammer racing swimsuit JK-ONE, the new exclusive racing swimsuit by Jaked, which combines high resistance and elasticity. An ergonomic jammer model, designed to guarantee high performance in water for all athletes. With longitudinally oriented panels, highlighted by polyurethane strips welded using the new ultrasound technology, which offer better toughness and are extremely elastic to allow optimal mechanical mobility. The seams are heat-sealed and become almost invisible, helping to minimise the effect of friction. A swimsuit with high hydrodynamic and water repellent capacity, thanks to the special ACQUAsuACQUA treatment with a double layer of fluorocarbon resins, which reduces water absorption and contributes to a better dynamic performance of the movements.
