For their Women’s Fading Light Heavyweight Jersey, Primal use high-performance double-weight SpeedPro fabric. With a brushed fleece back, this holds on to heat extremely well, insulating you from colder temperatures. However, as days begin to warm up or the intensity of your ride increases, impressive breathability ensures you’re not soaked in sweat at the end of your ride. A full-length front zipper makes it easy to control airflow and regulate your body temperature as weather conditions fluctuate. And with elasticated cuffs and hem, you’ll enjoy excellent comfort. The sport-fit is not too tight but not too loose, with space to layer up and 2-way stretch also offers plenty of easy movement when you’re on the bike.
