Santini: Our innovative GUARD rain shells provide complete rain protection in an aero, high-performance fit. GUARD Mercurio’s fabric has an improved outer layer that is a more tightly constructed knit for heightened rain protection. The newly added GUARD Nimbus is a lighter and more versatile option; ideal for rainy conditions in milder temperatures and incredibly pocketable.
