The Ultimate Guide to More Ethical and Sustainable Underwear

Our editors curate highly rated brands that are first assessed by our rigorous ratings system. Buying through our links may earn us a commission—supporting the work we do. Learn more.

 

Underwear is often the first thing we put on in the morning and the last thing we take off, so having a quality selection of bras, pants, boxers, briefs and more is of the utmost importance. There’s a growing number of more sustainable underwear brands for everyone, and we’ve rounded up the best picks for you.

The importance of comfy and conscious underwear

Underwear can make or break your day depending on how it feels and fits. And since it’s the thing that sits closest to your skin, it should be made to a high quality from great materials. So forget the polyester, and instead consider breathable, lower impact materials that are better for your skin and the planet, like organic cotton, bamboo, and hemp.

Here, we’ve selected the underwear brands all rated “Good” or “Great” against our methodology—they’re creating better basics, including bras, lingerie, boxers, and briefs that will make you feel comfortable and confident without compromising your values.
