It’s funny: I’ve been working in the world of sustainability and wellness for about a decade now, and it’s like only in the past year or so has everyone started realizing that most of our clothing is made of plastic!

Textiles are actually one of the largest sources of microplastic pollution. Every time we wash our synthetic clothing, tiny pieces of microplastics shed off the clothing and get washed down the drain. (These filters can help though!)

All of those microplastics not only harm the environment as a whole, but they also end up back in our food, water, and air. Microplastics have been found all over the human body, including in the brain, and have now been linked to various health effects, including heart attack and stroke.

Plus, there is some indication that wearing plastic clothing could be exposing us to other toxic chemicals. Not only has polyester clothing been found to be contaminated with toxicants such as BPA, but the microplastics may be acting as “carriers” to leach other chemicals through our skin and into our bodies.

And it’s not just plastic, either. Textiles are largely unregulated, and companies can add all kinds of potential toxicants to fabrics throughout the manufacturing process—from formaldehyde to carcinogenic azo dyes, PFAS, and more.

What to Look for in Non-Toxic & Low-Tox Clothing

Natural Fibers: In general, fabrics like cotton, linen, hemp, and wool are best. Even if they are blended with a small amount of synthetic (which is necessary for some categories, like leggings), it’s still better than something that’s 100% plastic.

Some semi-synthetics are better than others. (A semi-synthetic is a material that starts out a natural material, but then goes through so much processing that it can no longer be considered “natural” by the time it’s a final product.)

TENCEL is one of the best semi-synthetic fabrics in terms of human & environmental health (and it also feels really nice!). Some bamboo fabrics are processed in less toxic ways than others. Same with other types of rayon/viscose/modal. You can read more about that here. Be careful because bamboo fabric is very commonly greenwashed!

Third-Party Certifications: Although third-party labels are not perfect, they are generally better than nothing. Look for certifications like GOTS organic cotton or OEKO-TEX—these can ensure that the product at least met some third-party standards in terms of safety and sustainability.

Keep in mind, though, that these certifications do cost brands money. Therefore, just because a smaller brand does not have one of these labels does not necessarily mean it’s not a great choice.

PFAS-Free Clothing: PFAS are finally starting to be phased out of clothing, but it’s still something we need to look out for for now. If you see something that says something like “water-resistant” or “stain-resistant”, that could mean toxic PFAS “forever chemicals” have been added to it.

Other ‘performance’ claims like “iron-free” or “washless” can also indicate other potentially problematic chemicals have been added to it, such as formaldehyde.

When in doubt, don’t hesitate to reach out to the brand to ask WHAT gives the clothing that characteristic.

Transparent Supply Chains: In addition to safety and sustainability initiatives, I also prioritize brands that are committed to ethical manufacturing, whether that means regular factory visits or a Fairtrade certification.

Other things I look for are affordability (some of the brands below are definitely more affordable than others), size & gender inclusivity, durability, and plastic-free packaging.

MATE

Carries: Activewear, sweats, tees & tanks, shorts, dresses, casual wear, loungewear, underwear. Mostly women’s, but they do have men’s & kids’ collections too

Primary Materials: Organic cotton, linen, hemp

I love my MATE organic cotton clothes. I live in my organic cotton black sweatsuit during the winter!

Their clothing is produced in the heart of Los Angeles. This is a brand that’s dedicated to sustainability, fair trade practices, and clothing that just feels good. They use only non-toxic, natural, and organic materials for all of their clothing. (Their activewear does have small amounts of spandex, as does pretty much all low-tox activewear.)

They carry a lot of timeless staples, like tees, tanks, and pants in neutral colors. But then they also release limited-edition collections with more fun designs!

They also have an Extended Sizing collection which goes up to 3XL.

Other sustainability initiatives include a recycling program dedicated to reusing and repurposing old clothes, a Climate Neutral Certification (which means they offset their carbon footprint and reduce emissions), and plastic-free packaging.

Here’s my full MATE review.

They have a “Smart Casual Staples” collection for everyday wearing, and a “Chipped Canvas Workwear” collection that includes more durable jackets, pants, and shorts.

They say they are committed to using recycled and regenerative fibers wherever possible which will help “get rid of chemicals and pesticides which harm workers and leach into the rivers and help close the loop to create a cradle to cradle supply chain.”

A lot of their garments are made with Regenerative Organic Certified® Cotton. This certification aims to go “beyond organic”. The cotton used is grown in a way that not only eliminates toxic pesticides but also prioritizes soil rehabilitation, animal welfare, and improving the lives of farmers.

Make sure you check the product details before purchasing though because not ALL of their clothing is made with 100% natural and plastic-free fibers. Some of them use a cotton/polyester blend or other synthetics.

This B Corp has a bunch of other sustainability initiatives worked into their company as well, which you can read more about on their website or their Annual Sustainability Reports.

Happy Earth

happy earth organic squat proof leggings review on TheFiltery.com

Carries: Activewear, loungewear, sweats, dresses, tops, button-downs, tanks & tees, shorts, lightweight jackets (men)

Primary Materials: Organic cotton

Happy Earth has a great collection of non-toxic loungewear, workout clothes, and everyday wear.

They have men’s, women’s, and unisex options for organic clothes, and I like how they have solid neutrals as well as fun patterns. Some of their pieces are reversible too, so you can wear them in a variety of different ways.

A lot of their clothing is made of 100% organic cotton. The activewear uses a small amount of elastane (as does most non-toxic activewear). They’re made in Fair Trade certified factories in India using organic cotton that was locally grown, harvested, and dyed with certified non-toxic dyes.

This was one of my top brands for squat-proof leggings! Their clothing is so comfortable in my opinion.

Harvest & Mill

regenerative cotton gender neutral tees from harvest & mill

Carries: Tees & tanks, sweats, shorts, pants, socks, loungewear

Primary Materials: Organic, USA-grown cotton

Even though Harvest & Mill technically offers men’s and women’s collections for sizing purposes, all of their pieces are beautifully simple and non-binary in their design.

This is a U.S.-based company that offers regenerative cotton clothing and is on a mission to use only sustainable, low-carbon supply chains.

Harvest & Mill uses 70% less greenhouse gas emissions than traditional clothing brands as well as 50% less water consumption. Therefore they’ve been able to produce 100% carbon-neutral clothing (thanks in part its support of the Garcia River Forest reforestation project and the Capricorn Ridge Wind Farm).

Perhaps their biggest accomplishment is their all-American supply chain, which is five times smaller than traditional supply chains. They use regenerative cotton that’s grown in the United States, work with textile and sewing factories in America, and support local farmers, all helping to sustain and rebuild local communities.

In addition, Harvest & Mill produces clothing with all-natural and non-toxic dyes. This gives their clothes a natural, unique look that is as healthy for the environment as it is beautiful. Shop from tees, tanks, sweatshirts, sweatpants, socks, and more.

It may not be the most affordable option on this list, but if your budget allows for it, Harvest & Mill is one of the “cleanest” clothing brands on the market, both in terms of human and planetary health. Plastic-free clothes for the win!

Cottonique

It’s all free from things like latex, synthetic fabrics, harsh dyes, and chemical treatments.

Pangaia

Carries: Casual clothes, workwear, sweats, tees & tanks, shorts, coats & jackets, denim

Primary Materials: A mix.

Pangaia carries a lot of natural and low-tox clothing for adults and kids. They use a wide variety of materials, from 100% organic cotton and hemp, to plant-based semi-synthetics, to petroleum-based synthetics. I like how they are always innovating with their materials.

I have some of their bio-based activewear and, although it doesn’t qualify as “natural,” it’s one brand that can definitely compete with conventional synthetics when it come to fit, feel, and durability. (And I believe it’s at least better than petroleum-based fabric.)

I like that they offer more workwear and outerwear options as well. Organic cotton trench coat, anyone!?

Pangaia is also a certified B Corp company that is committed to sustainable innovation. They have various climate- and people-related goals throughout their supply chain, give-back initiatives, and more.

ISTO

Carries: Tees, button-downs, denim, trousers & shorts, jackets, knitwear, jackets

Primary Materials: Linen, organic cotton (virgin and recycled), wool

ISTO is a great place to find natural and non-toxic clothing for men, from tees to blazers to denim jeans.

They are committed to transparency, so you can find out where and how each garment was made right on the product page. Not only that, but they break down the cost of the material as well, so you can see how much it cost them to make the piece versus how much they’re charging you.

I love their “Beautiful Losers” collection, which basically just means there was a slight color mismatch so the pieces didn’t make it into their main collection. You can buy them at a 20-50% discount!

Jungmaven

Carries: Tanks & tees, pants & shorts, sweats, button downs, activewear, dresses, underwear

Primary Materials: Hemp, certified organic cotton

If you’re looking for casual hemp clothing, definitely check out Jungmaven. They have a lot of everyday wear options, from tees to button downs, to casual summer dresses. Most of their polyester-free clothing is cut and sewn in Los Angeles, CA, USA by partners who are Garment Authority (GA) certified, indicating ethical working conditions and fair wages.

Fun fact: It was actually illegal to grow hemp in the United States until the 2018 Farm Bill passed, which means it was impossible to make 100% made in the USA hemp clothing. Jungmaven’s founder, Robert Jungmann, is actually a founding member of the Hemp Industries Association, a group that was instrumental in passing the 2018 Farm Bill!

Christy Dawn

Carries: Dresses, tops & blouses, tees & tanks, shorts, pants, bridal, small men’s collection & unisex collection

Primary Materials: Organic cotton

Christy Dawn is basically the queen of sustainable dresses that are at once super comfortable and also gorgeous.

With an overarching mission of honoring mother earth with their farm-to-closet approach, this brand creates dresses out of organic cotton, regenerative cotton, regenerative silk-cotton, and deadstock fabrics that would otherwise go to the landfills. They use organic and non-toxic dyes as well.

Christy Dawn carries a variety of styles (maxi & mini, short- and long-sleeved, etc.) and a wide range of sizes (including extended sizes, petites, and maternity-friendly). I absolutely love their choices in terms of colors and patterns, too.

Although they’re mostly well-known for their dresses, Christy Dawn also carries pants, work-appropriate tops, unisex tees & sweatshirts, and more.

On each product page, you can view a breakdown of the costs that go into producing the garment—from the labor, to the trim cost, to the overhead, and more.

You can reach about their different types of cashmere here—from “super fine” to “super luxe.”

They also mix in some organic Tanguis cotton into some of their fabrics as well.

Their cotton comes with various certifications—some of it is Better Cotton Initiative (BCI) and some of it is Global Organic Textile Standard (GOTS). All of their dyes are OEKO-TEX certified.

As their name indicates, Organic Basics carries a lot of your basics: underwear, tees, loungewear, and other essentials that come in neutral solid colors.

Organic Basics carries a mix of both natural and synthetic fibers in their collection. Some of their pieces are made of 100% organic cotton, some mix in a small amount of elastane, and others are made of all-synthetic.

I’ve purchased several Organic Basics pieces over the years and I have liked a lot of them. I really like their underwear and tees (my favorite bra is from them!). But I wouldn’t necessarily recommend their leggings (unless you’re just wearing them as a base layer) because they’re not always squat-proof.

Based in Rhode Island, Gamine workwear was founded by gardener and nurserywoman, Taylor Johnston. This is truly a slow fashion, American-made brand. They use 100% natural textiles and each piece is “slowly developed, tested, & thoughtfully produced by seamstresses in Illinois, Texas, Tennessee, New Hampshire & Massachusetts.”

I love this description from their website: “We aim to celebrate the archeology of our garments and the lowest possible impact of our manufacturing processes. In an increasingly disposable world, our hope is that each Gamine garment is treasured, personalized, and a well-loved companion for years to come.”

Icebreaker

Carries: Base layers, tees & tanks, sweatshirts & hoodies, jackets & vests, pants & shorts

Primary Materials: Merino wool

Made primarily out of merino wool, Icebreaker is a great brand for layering. In addition to their regular leggings, tanks, and tees, they also have various kinds of thermal leggings, zip-ups, athleisure apparel, and more. Although many of Icebreaker’s stretchier pieces do include a certain percentage of synthetics, they also offer some 100% natural merino clothing as well (like for their t-shirts, for example).

Merino wool makes for a great alternative to synthetic activewear because of its natural durability, moisture- and odor-wicking properties, and temperature regulation.

Their website makes sorting easy, too—you can filter by activity (hiking, snow sports, running, lifestyle, etc.), by layer (base layer all the way to outer layer), by fabric, by price range, and more. They have options for both adults and kids.

This transparent brand has various ethical and sustainable initiatives throughout its entire supply chain. For starters, they’ve developed deep, long-term relationships with the sheep herders they work with in order to make sure all of the animals and humans involved are treated ethically. Their “five freedoms of the flock” ensure that sheep live in safe, healthy, and comfortable conditions.

Arms of Andes

plastic free activewear from arms of andes
plastic free activewear for men from arms of andes

Carries: Base layers & mid layers, tees & tanks, jackets & hoodies

Primary Materials: Alpaca wool

Arms of Andes is also one of the few brands that is 100% plastic-free. They offer a wide selection of natural apparel for men and women, including tees & tanks, sweatshirts, leggings, underwear, sports bras, joggers, and more. Great for hiking and outdoor workouts in colder weather, their collection makes for perfect layering and offers both mid- and light-weight versions of their pants and tops. Most of their offerings come in basic colors like blacks, blues, grays, and whites.

Because of the way alpacas have evolved living in the high altitudes of the Andes Mountains, their wool fibers can handle drastic temperature shifts from sub-zero at night to super hot during the day. Plus, it’s naturally breathable and moisture-wicking.

Arms of Andes’ “Leave No Trace Apparel” initiative is pretty cool, too. It means that all of their clothing is made out of completely biodegradable fabric (and apparently they’re the first outdoor clothing brand to do so). The only exception is their zippers, which is something they’re working on. (They’ve recently managed to switch to 100% natural rubber for their elastic bands!) But besides that, all of the fabrics, threads, and non-toxic dyes are 100% biodegradable.

Plus, they’ve got a “single-origin supply chain,” which means they carry out every stage of production—from sourcing alpaca fiber to manufacturing the garments—in one country: Peru. Their ethically-sourced alpaca wool comes directly from herders in the Peruvian Andes, whose families have been employing traditional techniques to rear alpacas and harvest their fiber for generations.

And they actually source a lot of their dye materials (like used coffee grounds and avocado stones/skins) from local grocers and restaurants around Los Angeles—how cool is that?

Like most other activewear, they do use small amounts of synthetics in their stretchy pieces.

Pyne & Smith

linen dresses made in the usa pyne and smith
linen clothing made in the usa from pyne and smith

Carries: Dresses & skirts, blouses & tops, trousers

Primary Materials: Linen

Personally, I love spending my spring and summer days in dresses. They’re just so easy to throw on (minimal decision-making required!) and wear to run errands, meet with friends, go to a baby shower, or whatever.

Pyne & Smith’s collection of size-inclusive linen dresses are both beautiful and practical (hello, pockets!). Choose between long or mid-length, short- or long-sleeved, solid-colored or patterned.

All of the linen fabric from this sustainable brand comes from Europe where they meet all of the REACH standards for safety. Then all of their custom patterns are sent to Los Angeles where the pieces are cut and sewn together by hand by skilled seamstresses.

Even though linen dresses are what Pyne & Smith does best, they also carry tops, pants, and overalls.

Stella McCartney

Carries: Dresses & skirts, blouses & tops, pants, workwear, formal, denim, jumpsuits, coats

Primary Materials: Various

You’ll have to check the product details when shopping from Stella McCartney because they do use a good amount of synthetics. But they also use plenty of natural fabrics as well. The dress pictured above, for example, is made out of GOTS certified silk. And the suit pictured is made of 100% RWS certified wool. They use organic cotton for their denim jeans, too.

This is a great place to look if you need something nice that you can’t find somewhere else, either for a job interview, a wedding, or a really nice winter coat. It’s not cheap, but it’s nice. Stella has been paving the way for high-quality, sustainably-minded fashion for a long time now.

Industry of All Nations

Carries: Tees & tanks, polos, pants, jackets, button-downs, sweatshirts, shorts, denim

Primary Materials: Organic cotton

Here’s another plastic-free brand that uses 100% natural materials. A lot of their pieces are completely undyed, making them a good option for people with the most sensitive skin.

A lot of their fabric is made of organic cotton, but they also implement recycled cotton, alpaca wool, and vegetable-tanned leather. Their signature blue dye is a fermented natural indigo dye, but they also use other natural dyes like iron vinegar for the black color, beetle resin for the pink, and chebula seed for the green. It’s not all vegan, but it’s all natural.

Even More Non-Toxic & Natural Clothing Brands

If you still haven’t found what you’re looking for from the brands above, here are even more clothing brands that prioritize natural & non-toxic fabrics and manufacturing processes:

Afends: This Australia-based brand carries a variety of natural clothes for adults made from things like hemp and cotton. They have dresses, denim, and more.

Allwear: This activewear brand is made mostly of bamboo and cotton. I love my leggings from them! They carry things like tanks & tees, shorts, and joggers for women & men. Check out my review here.

Boldwill: They don’t have a huge collection, but they carry activewear for men & women made of a blend of GOTS organic cotton, TENCEL, and some spandex for a few of the pieces.

Boyish: This denim brand uses a lot of more eco and low-tox cotton and dyes. They use a mix of OCS organic cotton, recycled cotton, deadstock fabric, and TENCEL. They work to reduce the amount of toxic chemicals used throughout their supply chain, whether that’s using plant-based dyes or Dystar (which isn’t all-natural, but uses less toxic chemicals than typical dyes).

California Cloth Foundry: This brand carries mostly plastic-free clothing made in the USA out of regenerative cotton. They mostly carry loungewear for women.

Conscious Step: They use primarily organic cotton. They mostly sell socks, but they do have a small apparel collection.

Filippa K: This is another place to find workwear and suiting, but you do have to sort through it to find the natural options. They use a good amount of synthetic fabrics. They do have a lot of sustainability initiatives though.

Hope for Flowers: They carry skirts, dresses, and blouses that have fun, colorful prints. Most of them are made of GOTS certified organic cotton.

kowtow: They offer beautiful plastic-free clothing for women & men, including dresses, workwear, everyday clothes, knitwear, pants, jackets, and more.

Reprise: This is a great activewear brand that uses primarily TENCEL for their leggings and sports bras (combined with GOTS/OEKO-TEX certified dyes). They have maternity options, too! Check out my review here.

Seasalt Cornwall: This UK-based brand is a good place to find printed dresses and skirts made of mostly either regular cotton or GOTS certified organic cotton. They also have other options like blouses, knitwear, a men’s collection, and more.

The Simple Folk: This is primarily a brand for babies & kids, but they have a nice women’s collection too. They have some beautiful dresses, blouses, knitwear, and pants. Most of it is made from organic cotton.

Tentree: They have a wide collection for men & women. They do use a lot of synthetics, so be sure to check the product details to find natural fibers. They do have some water-resistant outerwear that’s made using a PFAS-free finish.

Tripulse: This is another low-tox activewear brand that is made primarily of TENCEL with some synthetics mixed in. These leggings are more ‘high-performance’ and can handle a more intense workout compared to some of the other organic cotton brands. Here’s my review.

This guide will be constantly evolving, so if your favorite organic clothing brand is missing from this list, let me know in the comments and I’ll consider adding them!
