Frosty morning or cool afternoon, a good winter cycling jersey needs to keep you warm through changing conditions. Built with lightweight Polartec® Power Grid™ fleece, our Women's Prime Power Grid Long Sleeve Jersey helps regulate your body temperature thanks to the warm yet breathable knit construction. Perfect for sandwiching between a base layer and an insulated jacket, the sleek, four-way stretch design won’t restrict movement when you’re bundled up.
