Perfect comfort for better sleep. Naturally. The Magic of Merino

Because of Merino wool’s unique ability to regulate body temperature, it helps keep your baby warm when it’s cold and cool when it’s hot. That temperature regulation means that your child will sleep comfortably throughout the night, year-round – and that means a better night’s sleep for you too.

Better and Longer Sleep

A study done by the University of Sydney has found that a better night’s sleep is achieved when sleeping in wool. Merino wool is the perfect fiber to have next to your child’s sensitive skin. It regulates temperature, manages moisture, is easy to care for, soft, and durable. It’s naturally perfect.
