Cold-weather coverage for high performance riding. 

The ThermaFlow 4.0 Jacket offers sleek, cold-weather protection built for high-performance fall and winter riding. Strategically placed specialty fabric panels combine weather protection, insulation, breathability, and ergonomic stretch—delivering warmth up front with a wind-resistant, brushed fabric, and enhanced airflow out back with a breathable WarmYarn knit. The next-to-skin fit and elongated back are optimized for aggressive riding positions, while five rear pockets (3 top opening, 2 zippered) keep essentials secure. Treated with a PFAS-free water- and dirt-resistant finish and made with bluesign® approved materials, it’s streamlined, sustainable, and built to ride hard when the weather turns cold.
