How to Choose the Best Organic Underwear Brands

10 Best Organic Underwear Brands

Organic is considered to be a thing made of living matter or food that hasn’t been treated with chemicals. While there aren’t any edible underwear on this best organic underwear brands list, there are those that are derived from plant sources, are sustainably sourced, and are free from harsh chemicals.

“There are many everyday products people use without realizing their potential for toxicity,” said Dr. Michael Green, Chief Medical Officer at Winona. “Certain laundry detergents, nail polishes and even clothing can contain toxic, carcinogenic chemicals and hormone disruptors.”

Dr. Michael Green completed his undergrad at UC Berkeley. He went to St. Louis University for medical school and graduated in 1993. Dr. Green went on to do a Family Medicine residency at the Ventura County Medical Center and became board certified in Family Medicine.

During his Family Medicine residency, he fell in love with delivering babies. So, he did a second residency in OB/GYN and finished in 1999. He’s been an OB/GYN ever since.

Organic underwear doesn’t just speak of the materials they’re made of, even though in this list you’ll find hemp briefs and beech tree thongs. Here, the word “organic” spans out to include the sustainable practices employed by factories and the ethics of the brand itself—because organic isn’t a simple definition. It’s a feeling, a lifestyle, and a clean conscience.

Why organic underwear and why now, you ask? The answer is a simple one fueled by years of non-regenerative farming, deforestation, toxic runoff, and nonrenewable fabrics—because we must. But, also because they’re as kind to your skin and they are to the planet.

We’ve seen a shift in brands over time. Now, many are beginning to include at least one eco-friendly line in their collections, encouraging fabric recycling, and injecting, if only, just a drop of transparency into their sourcing and manufacturing processes.

Organic underwear is just one item on a long list of apparel, bedding, accessories, and shoes that is now reflecting the needs of today’s climate, and the category is booming.

Whether an entire emerging brand is dedicated to sustainable wear, or a well-known company has finally introduced its first eco-design, things are changing, and it’s about time, too.

10 Best Organic Underwear Brands

HARA is a brand created out of the need for sustainability in the fashion industry. Launched by Allie Cameron in 2016, it is the product of the founder’s first-hand experience with textile waste after traveling through India and seeing the rivers of plastic, chemical runoff, and mountains of tossed clothing.

It wasn’t long after that Cameron met with cotton farmers to figure out a way to solve this problem. She ultimately created a label where sustainability and design came together, hand in hand.

HARA’s mission is to “bring change and awareness to the man and environmental issues within the fashion industry while creating sustainable soft dreamy bamboo underwear that’s both rejuvenating and empowering.”

In its collection, you’ll find bras, underwear, loungewear, and sportswear in saturated earthly colors, varying cuts, fits, and styles, almost akin to that of swimwear.

Bamboo fabric is a great sustainable option, but the brand doesn’t stop there. It also reuses offcuts to negate textile waste and uses non-toxic dyes to prevent chemical runoff. Manufacturing in Australia, where the brand is based, HARA keeps its carbon footprint small.

Wearers mention how soft and high-quality the material feels. Considering the brand achieves such rich colors, the fact they’re naturally dyed is another high selling point that makes customers flock to HARA.

You’ll find all HARA underwear for $38.

6. Knickey

10 Best Organic Underwear Brands

Knickey isn’t a brand that added a sustainable option to its line of underwear, it was made to be that way from inception. Dreamed up by Cayla O’Connell Davis and Lauren Sagadore, this company was brought to life in 2017.

With expertise in supply chains and sustainability, the two had a few goals in mind when creating Knickey underwear. 1.) Make the perfect fit. 2.) Offer a range of styles and 3.) Use amazing fabrics.

Of course, the manufacturing needed to be ethical and the fabrics needed to be low-impact. The duo chose to do things the right way, the hard way, instead of green-washing semi-eco-friendly materials.

They chose organic cotton as the power player behind their line of underwear, which houses a range of styles like thongs, bikinis, and briefs, along with a few bralettes. Offered in trendy colors like cobalt blue and mustard yellow, each pair looks like a second skin, which means they’re versatile and easy to wear.

Related: Read our Knickey Underwear Review to see how they stack up.

Choosing organic cotton for underwear just makes sense. It doesn’t contain toxic chemicals, uses less water than normal cotton, and is super breathable for your lady bits, making Knickey a shoo-in for one of the best organic cotton underwear around.

Customers rave about how soft and smooth Knickey underwear are, and love how wearable and gentle they are on the skin.

What’s better than kind fabric and practices? A brand that also gives back. 1% of each purchase you make goes towards a nonprofit of your choice.

You can get a pair of Knickeys for $14 and do yourself, the planet, and others, a solid.

7. Everlane

10 Best Organic Underwear Brands

Everlane believes “we can all make a difference.” The folks at the California-based brand do this through its high-quality products, ethical manufacturing, and transparency. In fact, if there’s one thing this company is, it’s transparent nature.

Everlane was founded in 2010 by Michael Preysman and Jesse Farmer but was originally a menswear shop that soon expanded to include women’s apparel as well. Opening up and exposing its processes from start to finish, customers can learn all about where their apparel is made, by who, and why it costs what it does (hint: it’s much less than you think).

Teaming up with the most ethical factories in the world, Everlane’s collections are made with supremely sustainable materials. Designed to last, the brand helps to cut down on textile waste while eliminating the use of new plastic in its apparel, using organic cotton only, and using  recycled wool and cashmere.

Related: For more information check out our Everlane Clothes Review

Among its men’s and women’s apparel, you’ll find a few underwear options for both. The men’s section includes the usual suspects, boxers, briefs, and boxer briefs. Women can pick from thongs, bikinis, hipsters, and briefs, but you’ll also find bras and bodysuits too.

Its underwear has an oh-so-good look of comfort, like the type you don’t need to keep adjusting throughout the day. Customers write of extremely comfortable wear, enjoying their high-waisted styles and lightweight feel.

You won’t find a frill or ounce of lace in the women’s collection, perhaps because most lace is made from polyester (plastic). They have a standard yet sexy look offered in neutral colors like honey, grey, and burnt sugar.

You can get a pair of Everlane men’s underwear for $27 and women’s for $18.

8. Huha

10 Best Organic Underwear Brands

Huha, a fun name that tells us everything we need to know about this brand, like how it’s dedicated to the prosperity of lady bits, aka the humble vagina. Which to be honest, isn’t really humble at all, it’s actually incredibly temperamental.

Huha tells us that traditional underwear can be the root cause of bacterial conditions like yeast infections and UTIs, both of which the average woman has too many of throughout her life.

But, the right kind of fabric can help, and Huha uses Tencel Modal and Lyocell, made from a mixture of beech trees and eucalyptus. This specific blend also happens to be completely biodegradable. If you need to, you can toss them in your home compost and they’ll eventually break down with heat and natural gases.

If wearing literal naturals didn’t already make you feel fresh and clean, the company infuses its materials with zinc oxide. This mineral soothes irritated areas, resists microbials, and is still present in the fabric after 100 washes.

Another “real” company on this best organic underwear brands list, Huha is dedicated to transparency, and that means never retouching photos—stretch marks, discoloration, and all. It’s refreshing to see, and since this brand was made to deal with a real issue, it’s only right that its models reflect the same values.

Founded in 2018 by Alexa Suter, Huha has been the feature of popular magazines like Glamour and Fashion. Considering it’s a Canadian brand, these achievements speak volumes of its success.

With each purchase, Huha plants a mangrove tree that offsets 185lbs of cO2. Though its mission and integrity are what draw customers to the brand, its flattering and liveable underwear are what women get hooked on, with 88% of 2k wearers giving them a 5/5 star rating.

Available in 2XS-3XL, Huha thongs, cheeky, and brief styles are all $26.

9. Organic Basics

10 Best Organic Underwear Brands

Founded in Denmark by friends Christoffer Immanuel, Mads Fibiger, and Alexander Christiansen, Organic Basics is the product of the trio’s attempt to create “an honest, responsible, quality clothing brand where people could relate to brand values.”

What are these values? Well, care for the planet certainly emerges on top, alongside durability and simplicity. Partnering with trustworthy and certified facilities, Organic Basics offers apparel and underwear for men and women made from an array of eco-friendly materials.

You’ll find options like recycled nylon, Tencel Lyocell, and organic cotton among its expansive collections. For underwear, the brand opts for organic cotton only thanks to its breathable and soft nature.

Related: Read our full Organic Basics Review for more details.

Its eco-fabric options and transparency are what made Organic Basics an easy pick for this best organic underwear list, as well as its smooth colors and cute designs.

Organic Basics goes into depth about its factories, telling us they not only employ fair labor practices but offer perks to workers like free lunch and childcare services. You get the chance to peek into each of the brand’s factories, gaze upon the happy faces of those who work there.

Shoppers mostly mention the durability of the brand’s items and love its easy-going nature. It’s not fussy, it’s simple, but sticks to its guns when it comes to sustainability.

You can pick up a 2-pk of women’s organic cotton briefs for $38 or a men’s 2-pk of boxers for $70 made from either Tencel or organic cotton.

10. Boody

10 Best Organic Underwear Brands

Whatever Boody did to make its clothing look so soft, we’re hooked. The brand says it’s all thanks to eco-superstar, bamboo, the fabric the brand uses to make all of its apparel.

With the hope of filling “your everyday life with the softest, most comfortable sustainable clothing essentials,” Boody creates basics that are designed to be lived in, like underwear, lounge, and activewear.

Self-proclaimed “anti-fast fashion” heroes, the brand promises you’ll feel good in its breathable bamboo essentials that wick away moisture and leave you feeling fresh and clean throughout the day.

On Amazon, Boody women’s briefs have a 4.3/5 star score with buyers noting how stretchy the material is, but how well it holds up in the wash.

What Are the Best Materials For Organic Underwear?

10 Best Organic Underwear Brands

There are a lot of things underwear should be, like soft, breathable, and comfortable. With organic underwear, you’re also getting safe for sensitive skin, and good for the planet

The companies on this best organic underwear brands list use a range of materials, some more earth-friendly, others, softer on the skin. Below, we’ll go through a selection of green fabrics commonly used by these brands. It’s up to you to decide which one fits your needs.

Organic Cotton

You can’t beat the feel of cotton or the clean conscience of organic. Organic cotton is softer on skin than traditional cotton is, and it’s safer thanks to the absence of chemicals during processing. The fabric, mostly grown in India, is pretty breathable too, making it a prime choice for underwear.

But though organic cotton is certainly a better choice for you and the planet, it does take up 25% more land than plain old cotton does. In terms of sustainability, less land = better, but since it uses up to 90% less water, it’s a give and take.


You’ll see this one a lot from the names on the best organic underwear brands list. Made from plants, bark, and wood and totally biodegradable, Tencel is soft and buttery and gentle on the skin. It’s breathable too, and with all of those elements combined, it makes for a great pair of underwear.

Tencel is the improved version of Lyocell and is the brand name owned by Lenzing Fibers of Austria. The only real issue with this material is that it costs a little more to make, because of that, you’ll likely be paying a higher price for a pair of panties.


If you’re ever bought sportswear, you’ve probably worn modal. It’s man-made but is totally biodegradable, achieved from processing the cellulose found in beech trees.

The bulk of modal is made in China. It’s a supremely soft fabric that’s known for its moisture-wicking properties. It’s 50% more absorbent than cotton is, meaning the areas underneath stay dry and bacteria is less likely to accumulate.

Durable and stretchy, this fabric is perfect for underwear, but it is known to cause more sensitivities than other fabrics and can pill and stretch more easily.


Hemp has been around for centuries and grows happily around the world. The majority of the plant is grown in China, but you’ll also find hemp farms in the US and Canada.

Hemp fabric comes from the hemp plant, the same one that grows marijuana—only hemp doesn’t contain any THC, it’s just a naturally strong and pest-repelling fiber. Used by sustainable clothing brands to create durable fabrics, it grows quickly and is an easily renewable fiber.

In terms of underwear, hemp is a good pick because it’s super soft and strong, meaning your underwear should hold up with constant wear. The only con we could find out about hemp was that the fabric tends to wrinkle and crease more easily than others.


Silk is a highly debated material. It’s incredibly soft, sexy, and beautiful, but it has troubled roots—namely, the way it’s collected. If you didn’t know, silk comes from the larvae of silkworms. To get it, workers must take the larvae out of their cocoons (killing them) and collect the threads that line the inside.

Most of the world’s silk comes from Asia and over 60 countries around the world produce the highly-coveted fabric. Because of the way silk is collected, the price is usually quite high, but in general, it’s very strong and doesn’t wrinkle. It’s also naturally hypoallergenic and great for skin, making it an ideal choice for underwear.

Recycled Polys

Any recycled material is leagues ahead of those that are brand new. Extending the life of polyester means that new fabric won’t need to be created. Polyester comes from plastic, and in the recycling process, old material is melted down and new sheets are created.

As you can imagine, this process has pros and cons. Yes, you’re recycling, but during processing, microplastics are released from the fabric then washed down the drain straight into the ocean. With recycled polyester, because of the many different colors, bleach is usually used to get the fabric back to ground zero for further dyeing.

This fabric is sometimes used by sustainable underwear brands, especially for any that are made from lace. It allows them to offer a sexier style without compromising on their overall mission.


Bamboo is a sustainable superhero. It grows quickly, is easy to grow, and resists pests naturally. As the plant grows, it absorbs tons of carbon dioxide, meaning our air is much cleaner for its presence.

The majority of bamboo is grown in Asia, and when processed, the plant creates an ultra-soft, durable, and breathable fabric. Those three things combined make it an excellent choice for underwear.

There aren’t many downsides to using this type of fabric, but it can be expensive. It’s also more likely to pill than some other materials, which, for underwear, isn’t the end of the world, but can be frustrating.

How to Choose the Best Style of Organic Underwear?

10 Best Organic Underwear Brands

When it comes to underwear, comfort reigns supreme. The names on this best organic underwear brands list offer several different styles, and though no one is brand new to the concept of underwear, they may have stuck with one particular style all their life simply by default.

If you’re ready to slip into something different or simply want to learn more about what you’re sauntering around in all day, take a look at our summary of the different styles of underwear out there, just below.

Classic Briefs

Perhaps the most iconic style of underwear, briefs were made famous by big-name brands like Calvin Klein, shown off by slender models and beefy men. There’s a subtly sexy charm to this particular style…the way it grazes just above the waist and skims past the thighs.

Classic briefs are known for their comfort and versatility, and they’ll sit as nicely under a flouncy dress as they will a pair of skinny jeans. For men, briefs have been warned against in terms of decreasing sperm count, but for women, there’s no real disadvantage except for those with thicker thighs as the leg bands may dig in.

High-Cut Briefs

If briefs are too restrictive, high-cut briefs may be your saving grace. They come up in an ultra-sexy and curvy-girl-friendly style, elongating your legs and laying sweetly across your backside.

This cut is higher waisted than your average pair of underwear, so you’ll need to wear this style under high-waisted jeans or a dress.


Hipster jeans became super popular in the 90s and 2000s, with ab-bearing heiresses and slinky celebs cutting things shockingly close to the downtown area. Of course, underwear probably wasn’t present then, but for those who do want a little more coverage, hipster underwear is there to serve.

Though the ultra-low cut jeans trend has passed, regular fit jeans still show higher waisted styles, so hipster is a great option for a fuller coverage feel.


Comfortable, classic, cut to highlight the female form, bikini underwear sit a few inches below the navel and usually involve a higher cut on the leg and up the back. This style is great for anyone who likes a little less fabric but wants more coverage than a thong.

Wear them with cute, flowy skirts, jeans, or anything that’s not too tight. With a thinner band, Bikinis may not be super comfortable for some with larger waistlines as they tend to dig in, but you may find some styles with soft bands too.

Boy Shorts

Boy Shorts are like boxer briefs for the female figure. They’re ultra-flattering for a woman’s body, hugging curves and accentuating backsides. With a sexy, playful feel, this style is usually seamless or made in lacey fabrics.

The cut plus the fabric make them the perfect choice for dresses, office attire, or sexy boudoir shoots. Depending on the length of the leg and your body, you may find this style bunches up under tight jeans.


Thongs came into existence to do women a solid—hide panty lines. It’s said that those who love thongs really love them and those who don’t wouldn’t dare put them on.

No matter who’s wearing one, they provide a flattering look and are much more comfortable than a G-String. Thongs are ideal for anything tight—whether that’s a bodycon dress or pin-striped work pants.

But though thongs are our discreet friends, because they essentially sit tight to the skin in our nether regions, bacterial infections may be more of a risk than if you wore a looser fitting style like a brief.


G-Strings can either feel like nothing or be extremely uncomfortable—it’s all about the material and fit. With an ultra-thin string, they provide a seamless, smooth look no matter what you’re wearing.

G-Strings are generally very small underwear, which means they’re not period friendly. Because of the string, they sit close to your skin, may cause chafing and discomfort, and may spread bacteria.

What Are Organic Underwear Dyed With?

10 Best Organic Underwear Brands

Usually, organic underwear is colored with natural dyes. Because most of the picks on this best organic underwear brands list are biodegradable, that dye needs to be able to break down naturally as well and not cause soil toxicity.

Natural dye comes from plants and roots (think: the Henna plant and turmeric), but some organic underwear isn’t dyed at all. Organic cotton remains white while hemp is a taupe brown.

“Traditional clothing manufacturers use pesticides, dyes, solvents and flame-retardants, which can remain in the fabric and be absorbed by the skin,” Dr. Green said.

“While the thought of adding underwear to your list of organic purchases may sound silly at first, it’s actually a very health-conscious decision.”
