As a unique arm warmer in the market, the Giordana G-Shield Arm Warmers feature a special ‘Acqua Zero’ treatment bonds with the fabrics on a nano level. The treatment vastly increases the ability of the fabric to repel water. Brushed with Super Roubaix, the warmers feature ergonomically contoured panels for a comfortable race fit. Patterns are designed with the minimum number of panels possible so that there are fewer seams and less opportunity for moisture to infiltrate through to the skin.
