As we gather speed one pedal stroke after another, the Progress Thermo Long-Sleeve Jersey keeps us warm while winter winds blast around us. No matter if we're up on our hoods or in an aero position, this jersey provides the coverage we want for winter riding. Its brushed thermal fabric improves warmth, traps heat, and offers breathability to boot, and its versatility means we can wear it as a layer or on its own so we're well-suited to varying temperatures.
