LANACare uses only organic wool that is strictly certified, chemically untreated. LANACare wool has International Oeko-Tex Certification of Austria’s “Institute of the International Association for Research and Testing in the Field of Textile Ecology” and more recently KbT Organic Certification. No pesticides have been used on the fields where the sheep graze, nor have any harsh chemicals been used to wash the wool. The wool is as pure on the sheep as when it comes as clothing on your baby. No mulesing have been used on the sheep – a highly criticized way of “vaccination” of the sheep in Australia.
