The Castelli Prologo Jacket is designed for cosy riding in the cool and cold of winter, with an emphasis on breathability and classic cycling style.Constructed from GORE-TEX INFINIUM™ WINDSTOPPER® X-Fast fabric, the Prologo Jacket strikes a great compromise between warmth and breathability. The fleece lining is comfortable next to skin and lets out an excess heat and sweat with ease.The pattern of the jacket is the same of the Mortirolo Jacket, but the Prologo winter jacket is set apart from more modern designs with its block colours, harking back to the iconic national jerseys of the past. The Prologo is all about modern protection but with an emphasis on standing out on your next winter group ride.
