Castelli Size Chart Think of the Volata Jersey as the everyday aero jersey. Castelli has taken the fabrics from their fastest aero race jersey ever and used a cut that gives us most of the aero benefits while not being extreme. The Velocity fabric provides excellent wicking, while the little details like the mesh sleeve endings, the jacquard elastic in back, and the fourth zippered pocket make this jersey a staff favorite for everyday riding.
