Fox Flexair Pro long sleeve MTB jersey in black delivers ultra‑lightweight performance fabric that dries quickly and offers full range of motion. The mid‑rise cut and flat‑lock seams reduce chafing, while the integrated mesh panels enhance airflow for hot days. UV‑blocking weave protects skin during long rides, and subtle reflective piping keeps you visible on dusk trails. This medium size fits comfortably over layers, making it ideal for trail racing or casual commuting.
