Blanket made of natural fibers - 100% unbleached and undyed cotton on the outside and 100% wool filling inside. Wool provides air circulation, wicks away moisture and creates a comfortable climate for sleep with a uniform temperature. Wool regulates temperature, so it will keep you warm in winter and cool in summer, providing a comfortable and stable climate for sleep throughout the night. It stays fresh for a long time thanks to the natural property of wool to repel unpleasant odors. Machine washable at 30°C. In excellent condition, used for about six months, I will give away a duvet cover as a gift.
