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 list prioritizes brands that use organic fabrics and low or no-impact dyes and chemicals.
Soon, we’ll also be rolling out our new Brand Rating System to expand our assessment of a brand’s eco-performance, including climate impact and product durability. For more information on this system, check out our explainer.
We independently research all featured brands and we ask them to confirm their claims. In many cases we personally review recommended products. This post contains affiliate links which means we may earn a commission if you buy something. Learn more here.

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% non-toxic 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.
Organic Basics
About Organic Basics
Price Range: $20–$203
As their name suggests, Organic Basics is one of the best sustainable basics brands.
The Danish organic clothing company is improving the fashion industry with the help of organic fibers in their range of socks, tees, and 100% organic panties.
At their inception, they specialized in just one item: organic men’s underwear, like the Rib-Flex Boxers, made from soft, vegan-friendly, pure GOTS cotton.
Now you can shop both women’s and men’s organic cotton underwear in a variety of styles and pack sizes.
Organic Basics’ Ethical & Sustainability Practices
Materials:
OB offers mostly 100% organic cotton underwear that’s GOTS-certified.
That alone is a healthy choice, but if you’re wondering, “What panties are best to avoid infections?”, some of theirs also contain SilverTech (a polymer thread with sustainably-sourced silver), which helps to keep you fresh and odor-free.
Supply chain & labor practices:
To be a partner with Organic Basics, farms, and factories must use safe working conditions, ensure living wages, and prohibit child and forced labor. These entities are audited by SA8000 standards, and OB is both a Sedex member and BSCI-compliant.
Carbon commitments & green practices:
Sustainable materials are supported by a low-impact website, free carbon-neutral shipping, and a supply chain based entirely in Europe.
Rather than NO impact, they’re trying to create a positive one by participating in regenerative agriculture for their cotton farming—which converted an impressive 60,000 meters of farmland to land that goes beyond organic by capturing carbon.
Inclusivity:
Men’s organic cotton underwear runs XS–XL and women’s underwear XXS–XXL.
Subset

Subset’s Ethical & Sustainability Practices
Materials:

Some pieces, like the Mid-Rise organic cotton bikini underwear, contain a teeny tiny amount of blended elastane (5%) for stretch.
Supply chain & labor practices:
Subset will make you blush with how transparent they are (or maybe it’s just all this talk about bums).
The Subset HQ is based in Chelsea, NYC, but the rest of the magic happens in India, where they use third-party certifications to ensure their partners have the same values.
They work with an organic farm located in Ahmedabad, an organic ginner/spinner in Tamil Nadu, and an organic fair trade factory also in Tamil Nadu.
Safe and healthy working conditions, living wages, reasonable hours, and the right to unionize are standard along each step of your Subset knickers’ journey.
Carbon commitments & green practices:
Subset incorporates processes to reduce water usage and safely recycle it on their farms and factories.
Through the Recycling Program, customers can send old intimates for repurposing into new materials, like mattress batting and insulation.

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!
