Steel, leather, cork, and wool. These materials have remained a constant throughout nearly all of cycling's history, and for good reason. They wear like iron, last all-but-forever, and provide dependable comfort on even the longest rides. The Castelli Costante Wool Jersey combines the styling of yesteryear with technology and fit of modern-day cycling clothing.

• Two button-through pockets on the rear hold your spare tubular or a panini
