Though for several years, sustainable and ethical apparel labels have been taking the fashion world by storm, underwear and lingerie lines that are ethical and/or eco-friendly remained few and far between. Not anymore! Fortunately, designers are recognizing the importance of creating comfortable, beautiful underwear that is good for wearers, makers, and the environment alike.

What to Look for in Eco-Friendly Underwear:

Natural Fabrics: The brands below use natural, low-impact fabrics like organic cotton and TENCEL. These natural fibers don’t wreak as much havoc on the environment when they’re washed or thrown out at the end of their life. You’ll find that most underwear brands do contain a small amount of synthetic material like spandex, but as of right now, this seems to be a necessity in order to a) ensure garment longevity, and b) compete with non-eco brands in performance and comfort.

Environmentally-conscious manufacturing: The processes involved in creating textiles, especially high-performing ones, are often pretty harsh on the environment, using lots of water, chemicals, and energy, and leaving behind waste. Look for brands that are using more earth-friendly processes that reduce their impact.

Fair labor and transparency: As with everything you buy, check for fair labor practices. Look for brands that prioritize transparency and third-party certifications like Fair Trade and SA8000.

Comfort and confidence: Of course, your undies need to not only be comfortable, but also make you feel good in your body! Choose a brand and fit that will inspire confidence as you take on your day.

Created in Italy, CasaGIN is constantly looking for more sustainable and innovative fabrics, whether natural, organic, biodegradable, or recycled. Their simple, beautiful, and functional underwear and loungewear collections are made with eco-friendly, TENCEL certified Lyocell and Modal.

Founded in 1978, Only Hearts is a mainstay of New York’s sustainable fashion community.

Most of their pieces are manufactured in the NYC Garment District.

Uye Surana uses innovative methods for sustainable manufacturing. For example, different styles are designed cohesively and later cut harmoniously from the same fabric, rather than separately, to reduce waste, and the designer, Monica, uses natural materials such as flower petals, or unique hand-dyed techniques that preserve resources. All materials are sourced from both trusted overseas suppliers and a growing list of more local suppliers, and are assembled in Brooklyn or hand-sewn with care in the designer’s NYC studio.


Underprotection is a Danish brand based in Copenhagen and founded in 2010. They only use eco-conscious materials such as recycled polyester, recycled wool, lyocell, and organic cotton.

For Ladies, Gents, & Non-Binary Folks:

In an effort to create a healthier version of men’s underwear, Opok was started by two brothers (who also happened to play water polo professionally, representing team USA!) They wanted to create underwear that would be free of the pesticides and other toxins that so frequently found
in our clothing and undergarments. Opok’s cotton is sourced from the Izmir region of Turkey, which is known for having some of the highest quality fibers in the world. The farmers and dexters (clothes dyers) they work with are GOTS certified, which ensures that all agricultural practices are in line with organic standards. Plus, all of their shipping boxes are made entirely out of recycled cardboard and natural dyes in order to reduce the environmental impact of buying online.


PACT’s underwear, bras, undershirts, and socks are certified organic, Fair Trade, and affordable. They use low impact dyes and processes that decrease water use, too.


You probably know Allbirds for their sneakers, but they’ve recently forayed into the world of undies too! Their soft and comfy briefs, boyshorts, thongs, and bralettes are made from eco-conscious TENCEL mixed with their signature merino wool to give is a moisture-wicking quality to keep you feeling fresh. Sizes go up to XXXL.


Organic Basics uses eco-friendly materials like GOTS certified organic cotton and Tencel, as well as recycled wool and nylon. Everything is made transparently in certified factory partners around the world, where workers have safe working conditions and are paid a living wage and benefits. They also have an impact index, which measures the amount of waste, chemicals, energy, emissions, and water are utilized in their production process.

This brand mainly caters to men with a monthly shipment, but the women’s items look just as comfy and fun! The fabric is made in a carbon-neutral method that converts sustainably harvested beechwood pulp into MicroModal fibers. Then it’s woven in a GOTS certified facility, and sewn in Sri Lanka and Turkey under safe and fair conditions.

A leader in sustainability for the past four decades, Patagonia carries underwear for everyday wear and activewear. Their apparel is made with fully or partially recycled and natural materials and sewn together in fair trade factories.

Each pair of Thunderpants is made from fair trade certified New Zealand organic cotton yarn, which is grown without the use of any synthetic chemicals, fertilizers, pesticides, AZO dyes, heavy metals, formaldehyde or chlorine. Thunderpant’s insanely comfortable fabric is dyed and milled in Melbourne, Australia and every pair is cut and sewn in a women-owned, minimal-waste factory in Hillsboro, Oregon. Thunderpants works with local artists from Portland, Oregon to make their unique, eye-catching prints and designs.

All Boody items – including the shaper bras and thongs – are 95% rayon made from ECOCERT organic bamboo (and 5% spandex for stretch), which is processed in a closed-loop, non-toxic system. So unlike regular bamboo rayon clothing, which requires intense chemical processing, Boodywear manufacturing doesn’t discharge toxic chemicals into the environment. And bamboo is a highly renewable resource – it quickly regenerates after being cut.

Proclaim is an LA-based lingerie brand offering bras made out of recycled plastic bottles founded on the principles that fashion should represent all women and can be made in a way that does good for people and the planet. Made of soft and supportive recycled polyester, each Proclaim bralette diverts plastic bottles from landfills and oceans.

Tomboyx size and gender-inclusive bras and underwear are made mostly of OEKO-TEX certified organic cotton in women-owned facilities that the team visits regularly in order to ensure they’re being treated fairly.

They even have leakproof period underwear for lighter days and removable insert bras which accommodate inserts for post-mastectomy and transitioning.

WAMA Underwear for men and women is made from sustainable, GOTS Certified hemp and organic cotton. There are a lot of great things about hemp: it’s naturally anti-bacterial, anti-microbial, odor-fighting, and super soft and breathable. And trust me: these undies are super comfortable! The WAMA team works transparently with certified factories in China and oversee production there in order to ensure ethical manufacturing is taking place.


For Period Panties:

Not all of Thinx leak-proof panties are made from natural materials, but we’re including them because wearing period panties is way more sustainable than all of the waste we can produce from tampons and pads (not to mention they can save you a ton of money too). Thinx offers a variety of styles, from classic, air (ultra-thin), activewear, and organic cotton. You can shop by flow too, from super to light.

Same deal with Knix: these aren’t necessarily eco-friendly in their materials, but they could save you a lot of waste in period products.
