If you want all-natural nappies, free of synthetic materials like PUL, the wool covers from Allerlei Diapers are a wonderful choice for you and your child.
Made in Europe, it's made of sling fabric on the outside and fluffy soft merino wool on the inside. In the main wet area, the wool fabric is reinforced by a second layer. So everything stays tight and dry.
Wool is very breathable, hardly soils and regulates the temperature in a natural way.
