Not just another good-looking jersey, the Castelli Free Jersey FZ works hard to keep you warm and dry. Worn as an outer layer on cool days, or as a mid-base in the coldest weather, Castelli's highly functional Warmer fabric places a soft, fleece face next to your skin for thermal regulation and moisture management. New Warmer X-Stretch fabric on the sleeves allows a closer fit without feeling too tight. Features distinctive Italian graphics with full-length zipper, rear reflective accents, three back pockets and silicone gripper on the waist to keep the jersey from riding up. Recommended for temperatures between 59°F and 68°F.
