5,000 microfilaments are incorporated in a propriety manufacturing process where a highly-oriented microfilament core and dense microfilament wear layers are combined with an abrasion-resistant polymer resin.

This unique string construction provides a string with approximately 8% less thickness than standard products. Thinner string provides less wind resistance and allows shuttle to be hit harder and faster. Microfilament construction provides greater resiliency with no loss of strength and allows stringing at tournament-level tensions.

This string is recommended for professional players and advanced amateurs who require the world's best combination of playability and durability in a tournament badminton string. High-tenacity microfilament construction provides superior tension-holding properties when compared to standard badminton strings. XL construction provides denser wear surface for enhanced durability.
