The 4G string provides maximum tension and legendary power, spin, and comfort. To obtain Maximum Tension Maintenance, the molecular chains making up 4G are strategically aligned in a parallel fashion. This minimizes entanglement to ensure less creep. 4G is made from Luxilon’s famous poly-ether-ether (ALU Power) and doped with nucleates. The nucleates help to maintain the suppleness of the string and increase its strength

• Luxilon exceeds all quality standards for near-zero variance in string.  Pro players count on every set being identical.
• String is completely impervious to atmospheric conditions such as moisture.
• Reduce tension at least 10% lower than nylon strings to provide optimum playability as 4G does not suffer from tension loss common to other strings
