De Rerum Natura - Gilliatt

De Rerum Natura is a wonderful French brand specialising in the production of European merino yarn. Sustainability and transparency are at the heart of the company’s ethos and this translates into every aspect of their business practice.

50% of their wool comes from certified organic flocks raised by transhumance – an ancient practice in which flocks are moved from one grazing ground to another following a seasonal cycle. The rest of their fleece is sourced from small traditional farms chosen for their respect for animal welfare.

Their yarn is spun and dyed in a small mill in Rougnat, France. The mill uses a phyto-purification system to filter their water as well as dyes that are compliant to the norms set by REACH – an EU organisation in charge of regulating the use and production of chemicals in manufacturing. 

This is an ethical yarn that is muesling-free
