The ThermaFlow 4.0 jacket offers stylish protection from the cold, designed for high performance in autumn and winter. Strategically positioned special fabric panels combine weather protection, insulation, breathability, and ergonomic stretch, providing warmth at the front with a wind-resistant brushed fabric and improved airflow at the back with a breathable WarmYarn mesh. The snug fit and extended back are optimized for aggressive riding positions, while five rear pockets (3 top-opening, 2 with zippers) 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.
