Offering a harder feel, the Yonex Aerobite Boost badminton string set is best suited to more advanced players who want maximum control without sacrificing repulsion. This hybrid string ensures increased strength and less deformation at impact thanks to stretch-resistant Super Fibre (Vectran™) and Oval Shaped Side Fibre. It includes a super-thin cross string and a strong, polyurethane coated mains string to guarantee smashing power and sharp spin. Compared to standard Aerobite, the string provides more hold on the shuttle and helps to minimize the loss of energy.
