If I asked you to name a few things that you use every day, that directly touch your skin and that you can’t live without – would you mention underwear? 

You’d probably mention body lotion and deodorant, and maybe you would think of clothing in general. But underwear is one of those things we tend to forget about. It’s there, doing it’s job, but we don’t tend to give it the respect it deserves.

Why is Organic Underwear Important?

Think about it – underwear is cozying up to some of our most important body parts – all day long. It’s important that the fabric be breathable to avoid yeast infections (unlike synthetic materials like polyester fabrics), and free from toxic chemicals (unlike conventional cotton and most other fabrics.) Non-toxic underwear is key! 

Organic fabric is safest for our skin because the fiber comes from plants grown without pesticides, and to be certified organic the processing must be free from bleach, formaldehyde, toxic dyes and other toxic substances.

And we know organic is better for the planet because it is grown in a way that has a lower carbon footprint and environmental impact, and does not lead to chemically poisoned land and waterways. Instead, organic farming practices improve the soil and protect natural habitats – and that’s something to feel good about! Buying organic is a good step in being a conscious consumer

The organic fabrics and natural materials used for underwear include:

  • organic cotton
  • organic bamboo (can not be certified organic, but bamboo is grown without pesticides)
  • beechwood (not certified organic, but sustainably grown)
  • organic hemp (can not be certified but is grown organically)
  • low impact, natural dyes

Organic Underwear

Certifications to Look For

Any brand in the fashion industry can say they use some organic fabric, but look for these trusted third-party certifications to prove that they are truly certified organic, follow sustainable practices and are ethically produced.

Global Organic Textile Standard – GOTS is internationally recognized as the toughest organic textile standard because it goes beyond verifying the organic farming process to include every step of manufacturing. A textile product carrying the GOTS label “organic” must contain a minimum of 95% certified organic fiber, use non-toxic dyes and not be treated with bleach, formaldehyde or any other toxic substances. Strict social and environmental standards are also required.

Ecocert – A global leader in organic certification (used as certification for bamboo fiber because bamboo fabric is currently not eligible for GOTS certification)

Oeko-Tex Standard 100 – Comprehensive, third-party testing and certification for textile products at all stages of production. All components of a product are required to be free from a variety of harmful chemicals including formaldehyde, AZO dyes, pesticides, phthalates, heavy metals and more. Individual components such as dyes can also be Oeko-Tex certified. 

Fair Trade Certified – A respected international certification that promotes equitable trade practices, working with farms and factories around the world to empower workers by ensuring workers are paid fair wages, have good benefits and safe working conditions.

Certified B Corp – A B Corporation is a for-profit company that has been certified to meet rigorous standards of social and environmental performance, accountability, and transparency.

P.S. I’ve also got a post about sustainable fashion brands if you are interested.


  1. Tizz & Tonic is a really cute brand based in Bremen, Germany.
    Organic underwear made in Germany with fun prints and colors!

  2. George Blakey says:

    I’ve been buying organic underware from bgreen for years. They are made in the US but I don’t know much about their fabric origins. They are on the pricey side but their breifs are great.

  3. Mirinda Buxton says:

    Which do you use? I’m always afraid to just start ordering

    1. Thunderpants are my favorite because they are so incredibly comfy and cute. But they are a bit pricey. I’ve also tried Knickey, Pact and Wama – they are all great!

  4. Hello,

    Can you recommend a no show thong low rise undies for women?

    Thank you
