Cooler months can put an lot of demand on your gear closet, so the Summit Thermal Jersey is designed with versatility in mind. Wear it as an warm-yet-breathable outer-layer during fall and spring rides and use it as your insulating mid-layer when the mercury plummets during the winter. The technical fleece is constructed with an grid fabric that allows it to quickly transfer moisture while retaining heat to keep you focused on the ride, not the thermometer. The Summit Thermal Jersey features two zippered hand pockets, an zippered chest pocket, and an hood that's slim enough to fit under an helmet for really chilly rides.
