Irukandji is a very special rounded/rectangular polyester string. It is soft and provides great snap-back and feel. It enhances spin potential due to its added elasticity. It was engineered to function as the ideal Cross string.
Its smooth surface allows the mains and crosses to slide on each other, minimizing notching and maximizing snap-back, which increases spin potential. With remarkable feel and comfort, it bridges the gap between co-poly and multi filament strings.
