Why Merino Wool? 
Babies don't regulate their body heat very well and are prone to lose heat. 
Merino wool has natural temperature properties and assists their body naturally to regulate body heat. 
Babies can be prone to overheating when sleeping in synthetic fabrics. 
Merino is soft, comfortable non scratchy will provide an even warmth against babies skin. 
Two thin Merino layers are more effective than a single thick layer.
