Material and build: Made from polyester for long-lasting performance; constructed without threading to provide a consistent, reliable string bed. Why you need it: Designed to reduce shock on impact, these strings help protect the wrist, shoulder and elbow during play, making them a suitable choice for players managing minor arm injuries or seeking gentler feel. Performance highlights: Deliver high spin potential while remaining abrasion-resistant. Good toughness and overall durability maintain playability over extended use. Feel and comfort: Solid construction produces a more comfortable striking experience without sacrificing control or responsiveness. Compatibility: Suitable for racket sports that use standard replaceable strings; fits most rackets requiring polyester single-filament strings. (Refer to your racket’s stringing spec for exact length and tension.) Use scenarios Rehabilitation-friendly practice: Players recovering from minor wrist, shoulder or elbow injuries can use these strings to reduce vibration and impact stress during training sessions. Spin-focused play: Competitive or recreational players looking to increase topspin can benefit from the string’s high rotation characteristics. Frequent play and practice: Abrasion resistance and toughness make these strings a practical choice for regular club players who need durable performance between restringings.
