7 Organic Underwear Brands: No Ifs & Butts About Saving The Planet
Looking for au naturel underwear?
Don’t get your panties in a bunch—here’s a brief (pun intended) list of the best organic underwear brands.
What’s covering your bum is probably the last thing on your mind, but what’s “down there” deserves attention for several reasons.
Reasons include health problems, pollution, and worker hazards.
The underwear scene has seen improvements in recent years, thanks to the world of ethical underwear. While many brands are doing fine for your fanny, the best underwear is underwear that’s, well…natural!
Hence our narrow focus is on only organic underwear.
Everything we recommend to you on Sustainable Jungle is independently researched and we ask all brands to confirm their claims. To avoid waste, we test products on an as needed basis.

1. The Very Good Bra
About The Very Good Bra
Price Range: $40–$99
With a name like The Very Good Bra, do we need to say anything at all?
Driven by her win against breast cancer, Stephanie Devine started the brand to create the world’s first zero waste bra.
She went above and beyond, creating that along with 100% organic cotton underwear briefs that will completely break down in a worm farm after just eight weeks.
The Very Good Bra’s Ethical & Sustainability Practices
Materials:
The natural fiber underwear and bras don’t contain any polyester thread, nylon labels, synthetic elastic, or spandex/elastane.
Instead, they use 100% organically-grown cotton for the outer and liner, and Lenzing TENCEL™ thread. TVGB uses natural tree rubber instead of traditional spandex/elastane.
Everything can break down without a trace, including custom-designed hooks and eyepieces, GOTS-certified dyes, and soy ink labels.
Supply chain & labor practices:
Materials for TVGB’s 100% organic cotton panties are sourced from many locations, like Australia, Germany, Portugal, Italy, and the Netherlands.
Some of their partners are WRAP and SEDEX-certified, ensuring employees receive more than the local minimum wage, free healthcare, transport, and subsidized meals.
Carbon commitments & green practices:
The Very Good Bra is a Certified B Corp, ensuring they adhere to the highest standards for positive social and environmental impact.
Some items are funded from presales to minimize textile waste, and they use low-energy sewing machines and lights to reduce energy consumption in their facilities.
Besides compostable organic cotton underwear packs, all products are shipped in compostable or recycled recyclable materials.
Australian residents are in luck, as they can select the country’s first carbon-neutral courier at checkout, Sendle.
Inclusivity:
These organic cotton panties’ women’s sizes range between 8/XS to 16/XL.
If you’re unsure which size to pick, consult the Virtual Bra Fitter for a 10-minute Zoom call.
Community & charitable giving:
The Very Good Bra makes contributions to several organizations, and customers can select one of three charities at checkout, to which TVGB will donate $1 on their behalf.

Why Choose Organic Underwear?
Here’s the brief on why you should choose organic cotton briefs.
Your skin is the only barrier between you and the outside world, which is especially important when thinking about your bits down there.
Chemicals are the last thing you want to get close and personal with, but unfortunately, they’re a common ingredient in the conventional pair of underwear.
Take dyes, for instance; they may produce formaldehyde (a known carcinogen) when washed and worn. Who wants all of that down there?!
Even conventional cotton is typically dyed and bleached—which can cause irritation and provide a breeding ground for bacteria and yeast. We’d like to keep that far away from down there, thank you very much.
Not to mention all that plastic in synthetic fabric skivvies which leaves our planet with a terribly uncomfortable wedgie…
Choosing organic seamless underwear suddenly seems like a pretty seamless decision!
How We Found The Best Organic Underwear
What comes to mind when you think of sustainable fashion? Flowy fair trade dresses and ethically-made jeans, perhaps?
What goes on underneath all that is just as (if not more) important—so what are organic panties?
Materials:
What is the healthiest material for panties?
100% organic cotton underwear are ideal, but unfortunately, most options still include a tiny percentage of spandex or elastane to provide some stretch in the seat.
We’ll keep pesticides and plastic away from our patooties and opt for organic cotton instead. While hemp underwear brands were missing from this list, we’d happily wear their panties, too.
Other fabrics that didn’t make an appearance here but would count would be non-toxic wool underwear—but we would need to make sure it’s ethical wool.
Above all, non-toxicity is key, so as when looking for organic period underwear and organic cotton bralettes, we looked for third-party accreditations.
- Certifications: Global Organic Textile Standard (GOTS), OEKO-TEX, Forest Stewardship Council (FSC), Allergy UK
Supply chain and labor practices:
If dirty supply chains are like dirty underwear, we’re glad these brands are cleaning up.
At a minimum, this means no child or forced labor. Beyond that, we look for fair wages, safe working environments, no tolerance of abuse or harassment, and extra efforts to help support farmers and garment workers.
- Certifications: Fair Trade, International Organization for Standardization (ISO 9001), ISO-14001, Sedex, and Business Social Compliance Initiative (BSCI), Social Accountability International (SA8000), Worldwide Responsible Accredited Production (WRAP), Occupational Health and Safety Assessment Series (OHSAS 18001)
Carbon commitments & green business practices:
Recycled/reusable packaging is excellent, but we’re getting to the point where we want more! They say too much green makes you greedy…
We love seeing brands recycling production water, paying for carbon-neutral shipping, and accepting old underwear to recycle them responsibly.
Inclusivity:
All bottoms need covering (unless you’re a nudist), and we’re thrilled to see a range of sizes and models represented with these organic underwear brands.
Community & charitable giving:
Whether through donations to charities or a company fund to support environmental and social projects, brands should show that a new pair of underwear can mean so much more.
Final Thoughts On Non-Toxic Organic Underwear
Underwear is the most intimate of clothing you’ll ever use and own.
So, finding something that’s chemical and pesticide-free is pretty darn important. It makes you think twice about what’s in your top drawer, doesn’t it?
If you were wondering where to buy organic underwear (men, women, or kids) and what to look for, we hope these brands have answered your questions.
This is the part where we usually remind you to shop at second hand stores first, but in this case, we’ll skip that cringy thought.
You’ll be excused for not buying secondhand underwear. Just make sure you’re supporting an ethical underwear brand when you do—and sharing this article so others can, too.
