Merino wool is a natural insulator that helps keep your little one warm and comfortable in all sorts of weather conditions. It absorbs moisture vapor from your child’s skin, moves it away from their body and keeps them cool when it gets hot and warm when it gets cold.

It’s also an antibacterial, which helps to reduce rashes and keep your kiddos healthy. And since it doesn’t shrink or wash out like cotton, it can be a great choice for hand-me-downs.

When choosing merino wool clothes for your child, look for a company that uses ethical and sustainable practices from the sheep to the consumer, such as this one. They use ZQ certified wool and Bluesign approved fabric, meaning they can assure their customers that their merino base layers are made in the most ethical way possible.
