Designed to be the ideal jersey for high temperatures and/or long climbs. Extremely lightweight and breathable, it quickly achieves a high level of ventilation and drying. Ventilation is enhanced by 3D "open-weave" fabrics used to construct the front and back of the garment. The insert located on the upper back also promotes airflow throughout the entire back of the garment, especially when the cyclist is in an aerodynamic position.
