The STORM GUARD100 uses DryShield high-tech fabric and employs a special lamination technology that combines a multi-layer membrane material, which is waterproof yet breathable, with a high-performance textile base. One of the key features of this fabric is its excellent waterproof performance, specifically designed for rainy-day riding. The nanometer-scale microporous membrane structure effectively prevents water from entering, while allowing sweat to evaporate and be expelled, keeping the body dry and comfortable.
