The Chrono, Thermal LS Jersey starts with a brushed-back, high-loft Italian thermal fabric with DWR coating and a full-length front zipper interior wind guard that work together to keep cold air out and warmth in. From there, we add three Expandable Storage Pockets (ESP) that stretch to maximize capacity when you need to stow a jacket, gloves, and extra calories, and an extra secure zip stash pocket for cash and keys. Smartly placed reflective accents add the finishing touch to this go-to jersey for cold weather riding.
