The Women’s Endurance 4.0 Long Sleeve Jersey is built for early rollouts, cool temps, and shoulder season training sessions—with a fit tailored for women. Made with a merino wool blend fabric, it is naturally warming and antibacterial. The slim fit and extended back panel stay put in a riding position, while a PFAS-free dirt- and water-resistant finish helps shed light rain and trail spray. A full-length front zipper lets you fine-tune airflow, while four rear cargo pockets and two zippered stash pockets give you plenty of space to carry layers, snacks, and tools. With bluesign® approved sustainability, reflective details, and premium YKK zippers, this jersey is your go-to layer for when the weather turns chilly—but the ride doesn’t stop.
