The Professional model imitates natural gut string and the ISOSPEED Power Ribbons are used both for the core and for the surface coating. The surface coating is heat-sealed in order to increase its life expectancy; the Power Ribbons can move freely within the core. This results in very good ball acceleration and optimal arm protection.
