Spin and first-class comfort are the main features of Evolution Ribbed. Even at the first rallies you can feel the spin behavior, as well as the high elasticity and comfort. The Standardized Molecular Distribution Technology (SDM) developed by Polyfibre provides long lasting resiliency, stability and perfect control. The ribbed surface provides an extremely improved spin capability and prevents the string from slipping. Through the refined formula and surface treatment, the string grabs the ball better and can generate more rotation. Evolution Ribbed is ideal for the experienced tour-player adding exceptional spin, power and control, without sacrificing elasticity and comfort.
