If being able to see your breath was ever an excuse not to ride, no one's ever tried to use it on Castelli. The Castelli Zoncolan Jacket gives you a tangible advantage over Mother Nature. As tough as the legendary Italian climb, the Zoncolan is windproof, water-resistant, and warming in temperatures as low as 32 degrees. The Zoncolan is an excuse-killer of a jacket that leaves no reason to avoid putting in your base miles.
