FUNCTIONALITY AND STYLE. Functionality and style are the Formula 1.0 Collection watchwords, and the Stripe Short-Sleeve Jersey is no exception. True to the name, the five colorways combine striking colored shoulder panels with bold horizontal stripes. Die cut Air fabric sleeve hems keep the jersey in place on your arms, while its Ergonomic Cut, low collar and wicking, performance fabrics ensure comfort. On the back is a trio of pockets, along with reflective piping.
