Updated for 2020, our popular, high value CX jacket is now lighter but packs the same mid-level warmth, thanks to the inclusion of FXR’s advanced F.A.S.T. ™ membrane, and Thermal Flex ™ insulation that retains flexibility even in extreme cold. When the temps start to rise or you ride pace quickens, regulate your core temperature with our high-performance Dry Vent™ system with radial side body and chest vents.
