Organic Cotton Underwear from 13 Sustainable Brands

From bikini briefs and thongs to boxer briefs, these brands make underwear that is good for the planet. We checked out tons of sustainable underwear brands. Our team then rated each brand on parameters like supply chain transparency, emissions tracking and reduction, circularity, labor and ethics, and packaging and waste, and we filtered out the best-rated brands.

These brands use sustainable materials such as GOTS Certified Organic cotton, with a minimal amount of synthetic fibers (which are often added for stretch). Some of them even have a take-back program where they recycle old underwear.
