Skip the frills and fuss and opt for warmth and style with the Castelli Fondo Full-Zip Long-Sleeve Jersey when the temps start to dip. Packing in heat, the Fondo Full-Zip wraps you up with the high-loft fleece of Castelli’s Warmer fabric to trap in warmth while actively wicking away sweat. It fits close to the skin to optimize moisture transfer when you’re pushing through your sprints, and fit comfortably under a vest if the temperatures really start to plummet. With Castelli’s designers skipping obnoxious add ons, they were able to focus on ensuring a clean and clutter free cut with just the features that matter the most. Hightlights are the spacious back pockets for securing tools, gadgets, and snacks on the ride, and an extended tail that offers coverage when you’re down in the drops. In front the jersey is equipped with a full-length easy-sliding YKK zipper that can be opened for quick heat dropping during big climbs, or tucked nearly into the Zen neck flap at the collar to prevent rubbing when you tuck your chin down through a sharp breeze.
