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. By thermowelding the seams and waterproofing the zippers, our GUARD jackets weigh less than a combination of jersey and windbreaker while offering a similar level of total wind protection and thermal insulation.HEAVY RAIN PROTECTIONMade with the innovative Mercurio fabric. 100% Waterproof with triple layer membrane for extra inner warmth during heavy rain showers.
