The Primal Wear Air Force Eleven Cycling Jersey features Raglan Cut with 3/4 Hidden Zipper and 3 Rear Pockets. During moderate to vigorous activity, the heart rate increases which raises body temperature and creates perspiration. Primal Jerseys are designed to wick moisture from the surface of the skin, causing it to evaporate and lower the overall body temperature. This moisture management not only makes the garment more comfortable to wear but also allows the body to perform at its best. Made with 100% SpeedPro advanced moisture transfer fabric.
