The soft thermal fleece traps body heat while allowing moisture to escape, making it an ideal companion for cool-weather commutes or off-season trail laps. Designed with a casual fit, this jacket layers easily over a base or under a waterproof shell for colder days. Pre-shaped shoulders and elbows enhance mobility in the riding position, while zippered hand pockets give us a warm place to stash cold fingers at rest stops.
