This yarn is composed of recycled marine-recycled nylon and spandex, combining the high resilience of spandex with the skinny properties of nylon. The excellent resilience of spandex gives the yarn excellent stretch and contraction, while the nylon ensures the yarn's stiffness and comfort. This unique combination of properties makes this yarn ideal for lightweight athletic apparel, providing excellent elasticity and stretch while keeping a dry, comfortable and quick-drying wear experience.
