Aerodynamics play an extremely important role in the world of road cycling, and the Redux Istinto Short-Sleeve Jersey is designed to adhere to your body to create the most speed-efficient fit possible. The cuffs and bottom of the jersey are thermo-sealed and have an elastic, silicon-lined band on the rear of the jersey to ensure your jersey stays in place while on the move. Santini also continues the focus on aerodynamics by incorporating a triple inner pocket on the rear of the jersey, using an invisible thermo-sealed opening that adheres to your body when not in use to ensure no speed is lost.
