Recent research, funded by The Woolmark Company, has demonstrated that wearing superfine Merino wool next to the skin is therapeutic for those suffering from eczema.

When worn next to skin, superfine Merino wool works as a dynamic buffer, helping maintain a more stable humidity and temperature in the micro-climate between the fabric and the skin.
