With the Pro Jersey sitting so close to the body it's imperative any areas of irritation are removed and so Le Col have utilized apartment-locked seams throughout, giving a smooth and comfortable feel at all times. To keep you in control of ventilation the jersey uses a lockdown zipper, it's easily used, even at speed, to open and close the jersey for more or less airflow. Lastly, three low profile rear pockets provide space for gels and spares and a fourth waterproof pocket makes space for valuables.
