Engineered from 100% recycled polyester—half sourced from reclaimed tennis strings—the Tecnifibre X-Loop tee combines sustainability with performance. The inherent anti-abrasion properties of recycled strings deliver exceptional durability, while the breathable fabric requires no harsh chemical treatments. A natural silver-ion antibacterial finish keeps you fresh by inhibiting odour-causing bacteria in sweat. Tecnifibre's commitment extends beyond the garment: they actively collect used polyester strings of any brand for recycling, closing the loop on tennis waste.
