Merino wool is very soft, comfortable, breathable, yet isolating. It's one of the greatest natural fibers for children to wear and especially important for small babies, since it helps with the regulation of body temperature. The absorbent, hollow fibers in wool helps keeping the child's delicate skin dry. In the cold season, the numerous air pockets between the naturally crimped wool fibers also helps to retain body heat and keep warm air circulating freely next to the skin of your child. Wool clothing is perfect for every season, unique in the way it can accommodate fluctuating body temperature and help to keep body temperature more consistent. And as wool is naturally anti-bacterial it doesn't need to be washed as often as other garments, just airing will do. NEW bigger size!
