Fly Racing’s Youth Rayce Sonar jersey is engineered for high‑performance cycling with a long‑sleeve, four‑way stretch construction that delivers a snug yet flexible fit. The multi‑panel design incorporates a tag‑less comfort stretch collar with a gusset, ensuring the garment stays secure without compromising mobility. Standard fit sizing is calibrated to be neither too tight nor too loose, providing a balanced, ergonomic profile for young riders.
Ventilation is achieved through strategically placed side and underarm mesh panels that actively dissipate heat, keeping the rider cool during intense rides. The mesh ventilation panels are integrated into the overall multi‑panel construction, enhancing airflow while maintaining structural integrity. This combination of stretch fabric, ergonomic collar, and targeted ventilation makes the Rayce Sonar jersey a practical choice for youth cyclists seeking both comfort and performance.
