70% cotton/30% wool. The cotton is certified organic. The dyeing process is certified. The wool is mulesing-free. The unbleached color is the fiber’s natural hue and is neither bleached nor dyed. Even the finest wool may be subject to some pilling after repeated wear. Carefully remove any pilling. We suggest airing this garment or steaming with an iron. As a last option, hand wash cold or wash in the washing machine set to the wool-wash cycle. Use wool detergent. Gently reshape while damp. Dry flat.
