The Women’s Pro All Weather Jersey uses innovative Polartec® technology to deliver high speed performance in all weather conditions without compromising on weight or breathability. Taking the same advanced engineering used in our fastest Women’s Pro Jacket II, thermoregulating properties within the fabric offer consistent insulation from the elements when you need it most while still allowing heat to escape when intensity increases. A waterproof membrane will keep you dry through seasonal showers without adding bulk or sacrificing airflow. Exceptionally lightweight fabrics offer the perfect level of stretch for increased comfort when tackling the hills. A close, race orientated fit eliminates flapping when riding in an aggressive racing position.
