The Harkila Metso Half Zip is made from a warm, high-stretch, temperature-regulating TeckWool blend. This makes the sweater more durable than a pure wool sweater, so you will enjoy it for longer whilst retaining the warmth, breathability, and softness of wool. This stylish sweater is an ideal choice as elegant outerwear in spring and autumn, or as a warm midlayer on cold winter outings. It has a zip down to mid-chest height, a large handwarmer pocket, and a hidden radio pocket on the left chest.
