LUXILON TENNIS String 4G SOFT SET 125 is an advanced co-polyester monofilament string engineered as a more comfortable alternative to the original 4G. It maintains Luxilon’s signature tension stability and durability, while introducing improved feel and playability.

This string is approximately softer than the standard 4G, making it easier on the arm while still providing a firm and controlled response. It is especially suited for aggressive players and big hitters who generate their own power and need precision and consistency in their shots.
