Designed to maximize aero efficiency with its slim cut and back zippered connection, the Santini Men's Interactive 2. 0 Aero Jersey helps you maintain a competitive advantage during racing scenarios and serious training rides. Its fabric connection zips into Santini 2. 0 Bib Shorts for a highly aerodynamic, skin suit effect. The lightweight, breathable Artico front panel keeps you comfortable when you're riding hard on hot summer days, while the LycraKa uses a special micromesh Lycra for improved elasticity when you're in the tuck position. On the backside of this aerodynamic jersey, you'll find a two compartment pocket for easy storage and retrieval of energy gels and water bottles. Anti sliding elastic bands at the cuffs and hem provide a secure fit, also enhancing the jersey's aerodynamic, skin suit effect. Note that Santini recommends this jersey for temperatures ranging from 64 to 95 degrees Fahrenheit, making it ideal for warm spring and summer rides.
