The ThermaFlow 4.0 jacket offers elegant protection from the cold, designed for high performance in autumn and winter. Strategically placed special fabric panels combine weather protection, insulation, breathability, and ergonomic stretch, providing warmth in the front with a wind-resistant brushed fabric and enhanced airflow in the back with a breathable WarmYarn mesh. The close fit and extended back are optimized for aggressive riding positions, while five back pockets (3 with top opening, 2 with zippered) keep essentials secure. Treated with a PFAS-free water and dirt-resistant finish and made with bluesign® approved materials, it is aerodynamic, sustainable, and designed to ride decisively when the weather turns cold.
