Shoulder seasons can put a lot of demand on our gear closet, so we appreciate that the Summit Hooded Thermal Jersey from PEARL iZUMi is designed with versatility in mind. We wear it as a warm, breathable outer-layer during fall and spring rides and use it as our insulating mid-layer when the mercury plummets during the winter. The technical fleece is constructed with a grid fabric that allows it to quickly transfer moisture while retaining heat to keep us focused on the ride, not the thermometer.
