Yonex badminton string and made from the new material Forged Fiber.
While thinner strings tend to have higher repulsion, there has always been the issue of low durability. FORGED FIBER was developed to solve this very issue. Ordinary nylon had a limit to the strength of its fibers, which is why Yonex reconstructed the fibers on a molecular level to build stronger bonds for lasting durability. This FORGED FIBER gave Yonex more freedom to construct thinner strings without compromising durability.
Core Fibre: High strength Nylon
Outer Layer: FORGED FIBER
