Product details
Cold protection for high-performance rides. The ThermaFlow 4.0 Jacket offers elegant cold protection designed for powerful riding in autumn and winter. Strategically placed specialty fabric panels combine weather protection, insulation, breathability, and ergonomic stretch – providing warmth at the front with a wind-resistant brushed fabric and improved air circulation at the back with a breathable WarmYarn knit. The close-fitting design and extended back are optimized for aggressive riding positions, while five back pockets (three open at the top, two with zippers) securely store essentials. Treated with a PFAS-free water and dirt-repellent coating and made from bluesign® certified materials, it is streamlined, sustainable, and built to perform hard when the weather turns cold.
