This jacket features Clima Barrier® with high stretch, windproof, and breathable properties on the front, and a highly breathable material on the back. It blocks cold wind from the front while effectively releasing stuffiness inside the garment. With a thin, slim silhouette that fits the body, it offers high mobility and is suitable for high-intensity activities in cold seasons, such as speed hiking and running. It has reflective markings on the waist for increased visibility at night.
