The ThermaFlow 5.0 jacket blocks cold wind and keeps you warm while allowing your body to breathe—perfect for intense rides in cool conditions. Its specially designed double-weave fabric combines a windproof, water-repellent outer layer with a ventilated fleece inner lining made from lightweight, thermally efficient GRAPHENE yarn. Made without laminate, it maximizes airflow while reliably keeping the elements out—thanks to a PFAS-free dirt and water-repellent coating, taped seams, and snug-fitting elastane cuffs. The Ride Adaptive Hood (RAhD) features a patented magnetic system that keeps it in place—either secured to your helmet so it won't blow away at speed or fastened at the back to prevent it from flapping like a parachute—while the unique ClimbVent connector allows for riding with the jacket fully open when more airflow is needed on long climbs. It works great on its own or as a midlayer under a hardshell when the weather turns. Made from bluesign®-certified fabrics, the ThermaFlow 5.0 jacket is built for cold—when you bring the heat.
