Whether it's really chilly or just a little cool, this sweet jacket from Bellwether has you covered. With a quick pull of the sleeves, the Convertible Jacket changes from jacket to vest, making this lightweight piece ideal for a variety of weather conditions. Its tightly woven Exo-Grid fabric is durable, windproof and water repellent. Plus, the shock-cord waist and full zipper guard keep water and cold out. The Convertible is also well ventilated to let off steam when you pick up the pace.
