Our Thermoactive jerseys use a recycled fleece-backed fabric that offers great insulation with minimal bulk, as well as excellent moisture-wicking and antibacterial properties. Simply swap out from your usual short sleeve jersey when the temperature falls towards single digits, or use as a mid-layer to keep on riding through the depths of winter. Note: The Thermoactive jersey is not a jacket, and is designed for a snug fit over a baselayer. If you want to pack in more layers, please size up.
