Castelli Costante Jersey FZ

The Castelli Costante Jersey FZ was named after Costante Girardegno, the 1919 Giro d’Italia grand winner. Costante’s cycling clothing was designed by Vittore Gianni which later became Castelli. In the next century, Castelli continued to use wool which has natural wicking features. After further research, Castelli improved the wool fabrics originally used by Costante. The 2016 Costante Jersey is made with Nuyarn performance wool fabric that has virgin wool wrapped around a nylon core to reduce shrinkage and improve moisture management. Nylon has also been added to make a stronger and more durable fabric. The full-length YKK® zipper is easy to open and close and the three rear pockets are buttoned giving the Costante that classic style.
