The Pro Jacket is our fastest winter jacket. Together with advanced Polartec® Power Shield® technology and input from WorldTour riders, the Pro Jacket delivers breathable showerproof and windproof protection for high tempo sessions in winter conditions. Polartec® Power Shield® is a patented bio-based performance fabric with a durable waterproof and windproof membrane that will keep you protected without compromising on breathability or weight. The fabric uses a new molecular diffusion technology designed to move water vapor out of the fabric while maintaining a barrier against water droplets. Free from micropores, it won't lose breathable performance over time and can withstand stretching, washing and the brutal winter elements. As part of our Pro Collection, the jacket is lightweight and cut to fit close to the skin, elmininating flapping and optimising aerodynamics when riding at pace.
