The Global Organic Textile Standard (GOTS) is the world's leading textile processing standard for organic fibres. GOTS certification guarantees social as well as ecological standards and the entire textile supply chain is independently vetted.
There's a long list of criteria that must be met. As you'd expect, toxic chemicals are prohibited and manufacture is kept separate from other textiles. On top of that, workers are safe, get a living wage and are free to unionise, while child labour and discrimination are prohibited.
We've found that GOTS certification is the best way to ensure that our fabrics are truly what we mean by organic. The standard can't be fudged and the meaning of the word can't be diluted or lost in translation.
