Castelli Fly Jack-sey Jacket – The Hybrid Performance Revolution

The Castelli Fly Jack-sey is a revolutionary garment that blurs the line between a jersey and a jacket. Designed for the most demanding cyclists, it provides the protection of an outer layer with the lightweight, aerodynamic feel of a racing jersey.
