The ThermaFlow 5.0 jacket blocks cold wind and keeps you warm while letting your body breathe: perfect for high-intensity outings in harsh weather conditions. Its custom-developed double-weave fabric combines a windproof and water-resistant outer shell with a breathable fleece inner made with lightweight, thermally efficient GRAPHENE yarn. Constructed without a laminate, it maximizes airflow while still protecting from the elements thanks to a PFAS-free dirt and water-resistant finish, taped seams, and snug elasticated cuffs. The Ride Adaptive Hood (RAhD) features a patent-pending magnetic system that keeps it in place, secured to your helmet so it doesn't fly off while riding or to your back so it doesn't billow like a parachute, while the exclusive ClimbVent connector allows you to ride with the jacket fully open when airflow is needed on long climbs. It works great on its own or as a mid-layer under a shell when the weather changes. Made with bluesign® approved fabrics, the ThermaFlow 5.0 jacket is built for the cold when your spirits are hot.
