Nui Organics was born in New Zealand in 2004. Respect for both people and planet has always been at the core of the nui brand. As much as possible they use certified organic materials and production methods, work with factories that mirror our environmental and social philosophies and constantly seek to improve. Nui merino clothing uses merino wool that is certified organic to GOTS. It is completely free of harsh chemicals normally found in wool growing that can contribute to wool sensitivity or wool allergy in some people.
