Sustainable Fashion

Last Updated on November 2, 2023

Look good and feel great in these fantastic activewear brands! I’ll be the first to admit that when it comes to working out, I sometimes struggle to find the motivation. One thing that helps me get in the mood is donning an activewear set that I feel good in! It’s a simple way to trick my brain into thinking that I want to exercise. Silly brain, so easily convinced.

There are so many sustainable activewear brands to choose from today. Ethical activewear has become easier and easier to find! Start with your local thrift store and secondhand shops first — it’s the most eco-friendly option. If you want something new, check out athletic wear brands like Girlfriend Collective, Wolven, Summersalt, REI, and Pact to name a few. They’ve all got sustainable workout clothing on deck!

As confident as I am in the second hand market, undies, sheets, and workout gear are some of the pieces, that I’d really like to buy first hand. When it comes to buying workout gear, the struggle of all struggles is polyester. Most workout gear is made from polyester. Natural fibers absorb moisture, whereas poly (which is plastic) doesn’t.

Polyester when woven across allows for the moisture to move from the skin through the shirt and evaporate. I’m not a huge fan of polyester in my clothing, but going on a run with cotton leggings, is not super comfortable. In fact, it makes jogging almost down right unbearable cause it makes my legs itch. But, I don’t mind wearing cotton leggings when it’s a low/non-sweat activity like restorative yoga.

Whether you like to wear, activewear to be, well, active, or if you’re looking for something comfortable to wear while working from home, there are natural workout clothes out there for every taste and style. Athletic wear has a reputation for being made out of synthetic materials (boo) but there are brands out there for whom sustainability is key.

what makes athletic wear ethical?

When hunting around for the best sustainable activewear brands, you’re going to want to first understand what ethical activewear means. All good sustainable clothing brands work to minimize the environmental impact their products leave on the planet. This includes their production methods, the materials they use, as well as the way they ship their clothing.

They should also support Fair Trade and fair labor. You never, ever want to buy things from a brand that doesn’t treat their workers fairly — that’s one of the main tenets of sustainability, after all.

Sustainable activewear brands use natural or recycled materials, while also giving you the high-performance aspects you’re after. Because you’ll likely be wearing this type of clothing to do some sort of physical activity, it also needs to be breathable and comfortable.

This may seem like a lot of boxes to tick but, trust me, there are several brands out there that work hard to provide all of the above. Let’s take a closer look at a few of my faves!

sustainable activewear brands to try now

1. yogavated:

Yogavated is made in Phoenix, AZ. They source their fabrics from deadstock material and are a zero waste company!

During the production process, all of their scraps are saved and turned into tag strings, head bands, and they use the smaller scraps to stuff dog beds which are donated to the local shelter – could there be ANYTHING CUTER!?

They partner with artists to create their own mini-collections. I think it’s a really beautiful collaboration and you can check out their featured artists here.

Their leggings are made with a sweat tech fabric that combines cotton knit jersey and polyester so it’s breathable and sweat wicking making this a good choice for more active classes!

My top picks are the summit power legging. Don’t miss out on one of my go to sustainable activewear brands!

Yogavated is offering 25% off your first purchase with the code ‘GZW25’.

2. la relaxed:

LA Relaxed is made in Los Angeles, CA. They are committed to using sustainable, plant-based fabrics that are known for better temperature regulation.

Modal: Sustainably grown and produced from Beech wood using a low impact, water-recycling process, this dreamy fabric is luxuriously soft, breathable, and naturally temperature regulating.

Cotton and Hemp: GMO and pesticide free Organic Cotton is paired with Earth-friendly hemp to create a soft yet durable fabric. It’s naturally hypo-allergenic and UV-resistant.

Tencel: Made primarily from Eucalyptus using a closed-loop process that minimizes water and chemical use, Tencel fabrics are naturally temperature regulating and antibacterial.

Tencel has a soft, soothing hand feel and offers long-lasting color retention.

I’ve had several LA Relaxed pieces for a couple of years and they are very soft and very cozy.

I like to wear my joggers to morning yoga, walks with Nala, and of course just lounging around the house.

My top picks are the piped jogger in azure (seriously the jogging suit of my dreams) and the smooch sweatshirt in oatmeal.

3. prana:

Prana is made all over the world, but they are committed to ethical standards and sustainability.

The town they’re headquartered in doesn’t provide composting, so the brought it in themselves – I thought that was super cool.

During the holiday season, they donate a portion of the proceeds from a select collection of items to Outdoor Outreach.

This non-for-profit organization transforms lives by connecting underserved youth with the outdoors—a mission that’s been close to our hearts for a number of years.

I’m very impressed with the traceability of their supply chain and how they’re working to manage forests.

While I am a huge proponent of modern plant based fibers like Modal an Tencel, we need to make sure the forests are being managed properly.

And, of course I’m super excited that they’re phasing out polybags!

It is very difficult to do since our laws in the US require that most clothing items arrive individually wrapped in plastic to stores.

It’s difficult to work with distribution houses in a plastic free manner which is another blog post all together.

4. girlfriend:

When girlfriend collective rolled onto the scene, they were one of the first to take plastic water bottles and turn them into activewear.

They blew up and are pretty much sold out of everything right now.

What I like about them is how detailed their about page is from how their fabric is made to their factories.

This is where their plastic bottles come from that they use to turn into fabric, “Taiwan, where we source all of our post-consumer water bottles, used to be called “Garbage Island”. A small island nation of 23 million people, the government saw the danger of ignoring the problem, and through widespread change has transformed Taiwan into a world leader in recycling.”

I hear their next drop is Feb 11. So, if you’re looking to snag a new set my top picks are the midnight compressive leggings, the midnight paloma bra, and the smoke margot wrap.

5. outdoor voices:

Outdoor voices is one of my favorites for their bright colors.

They manufacture in the US, China, Vietnam, Cambodia, Italy, and Portugal.

They prioritize quality, compliance to worker’s safety, fair wages and benefits, and dedication to minimizing environmental impacts on water waste and emission. 

When it comes to fabrics this is what their website says, “We work with specialists around the globe to develop high quality, made-to-sweat-in textiles.

“While activewear has a track record for being tough to produce and recycle, we’re passionate about finding ways to manufacture our materials and styles more sustainably. 

”We love our lightweight Rec Poly (recycled polyester) fabric, which is crafted from post-consumer water bottles that are melted down and turned into fibers.

“For our Merino gear, we partner with Global Merino—leaders in sourcing sustainably raised wool, bluesign® certified—who can trace their fibers back to the sheep they came from.

“Our Seamless collection also works to decrease waste, as these styles are knitted as a tube rather than cut and sewn together—no scraps.”

I also love that you can buy a set for a discount!

I always like to buy sets together so it’s great that they encourage and even reward you for mixing and matching.

My top picks are the 7/8 Springs Leggings and the navy athena crop. Can you tell I have a thing for blue workout clothing?

6. alternative apparel:

Alternative Apparel is a fashion lifestyle brand best known for comfort, simplicity and its commitment to sustainability.

They ensure fair, safe, and clean workspace conditions for everyone in their supply chain and focus on using sustainable fabrics like organic cotton and post-consumer recycled polyester.

Their polyester recycles approximately 120,000 bottles annually.

They use eco-friendly, low-impact dyes, biodegradable fabric softeners and wash their clothing with reclaimed water.

Their eco-friendly packaging saves 2,100 trees, 400 cubic yards of landfill, 860k gallons of water, and 120 tons of CO2 annually.

Their sustainable workout clothes look great and are super comfy too.

7. tentree:

Tentree is one of my favorite sustainable activewear brands. I talked about them a bunch in this post about my five fall hiking essentials.

Tentree was founded in 2012 with a goal to deliver well-crafted, sustainable athletic wear and with each purchase 10 trees would be planted.

To date they have planted more than 24 million trees!! Yes, you read that correctly 24 MILLION trees and counting.

These trees have been planted in Canada, United States, Nepal, Madagascar, Haiti, Senegal, and Cambodia.

Their projects are truly outstanding and you can read more here.

Beyond, their amazing projects they also use sustainable fabrics like hemp, organic cotton, and recycled polyester.

8. satva:

Remember what I said about running with cotton? Well, I was totally wrong.

After trying Satva’s organic cotton leggings, I realized my old non-organic cotton leggings weren’t designed for action and HIIT.

Satva has cracked the code.

They’ve managed to master both high-tech sustainable workout clothes and organic natural fibers. These leggings are the ones I’m honestly reaching for the most.

Beyond just being amazing, perfect for jogging, and ADORABLE (I love the kosha bra top), their mission is what really speaks to me.

They are dedicated to improving the livelihood and economic prosperity of small and marginal organic farmers in India.

Satva also donates a portion of all their proceeds to its local community and agricultural programs.

My top picks are the giri semi-fitted gray jacket, kosha bra top, and the perma high-waisted leggings. I seriously LOVE these leggings!

9. icebreaker:

This is another natural workout clothes brand that I SWEAR by. I got my first pair of Icebreaker leggings last year, and have already bought two more pairs.

I have their biker shorts, four t-shirts, and a sports bra too. Icebreaker is quickly becoming my go-to for ethical activewear when working out.

Icebreaker is made mostly from merino-wool which is anti-bacterial, anti-microbial and rockstar for temperature regulation.

Merino wicks moisture away from the body naturally so you can stay comfortable on even the more strenuous outdoor activities.

Icebreaker has a very strict animal welfare policy that ensures a healthy, low-stress quality of life for the sheep.

They produce a transparency report every year that covers everything from social responsibility, worker safety, animal welfare, and environmental integrity. Read the Report

My top picks are the Women’s Tranquil Tights which even have a band on the inside to cinch the waist and the women’s Cool-Lite Meld Zone Long Sports Bra.


what are the benefits of sustainable clothing?

The benefits of sustainable clothing are tenfold — and then some. There’s a reason why I’m so passionate about zero waste, people! When you buy sustainable activewear brands, you’ll help save precious natural resources, reduce your carbon footprint, support fair, and safe working conditions, and (quite simply) help save our planet. Natural workout clothes are a great place to start.

what makes a clothing brand sustainable?

The goal of all sustainable athleticwear brands is to use production and manufacturing processes that affect the environment as little as possible. These brands focus on using organic, recycled, and natural materials. There is also a large focus on fair and safe working conditions. The best sustainable brands are carbon neutral and use sustainable energy.

can you recycle old workout clothes?

You can, and I definitely encourage it! Consider first donating your old activewear to your local secondhand shop. You can also organize a clothing swap with your friends, neighbors, or family. If you’re handy with a needle and thread, you can even cut up sustainable leggings or other sportswear to make leg warmers or headbands. If your gear is too worn out to be donated or repaired, you can also find a collection bin that recycles old clothes. USagain is a great option.

  1. I’m going to have to try these out! I hate everything about Lululemon but they have amazing leggings and I’ve been looking for an ethical alternative. Unfortunately it doesn’t seem like any of these leggings have an inner drawcord (which prevents the waistband from slipping) but I might have to give them a try anyway.

  2. Good to know! Haha, for as much of a germaphobe I am I do have to say that all my workout wear is thrifted! (With the exception of some sports bras). I also have a lot of Jonny’s old track gear. I have no intention of buying Nike new but I feel better knowing I’m wearing it instead of going to landfill 😉 I’ll use this list in the future for sure!

  3. I am unsure about supporting prana. was looking at prana for organic cotton jeans and they contained DuPont polyester. Not sure I can support a company that partners with DuPont.

  4. I swear by Bhumi – organic cotton, fair trade and zero waste packaging. Plus it’s the softest fabric I’ve ever felt. As I’m a student, I usually save up my wish list and buy during Easter or Boxing Day when they have a sale. Would especially recommend for Australians as it’s based in Melbourne.

  5. Thank you for posting about these sustainable athletic ware companies. I will definitely be referring back to this list the next time I might need some new leggings!

  6. Love these! That jogger looks like something the Bionic Woman would wear, so I am in!
    Question Kathryn-have you posted on how to reduce our energy consumption? Last night I was drinking out of my reusable cup with my handmade napkins while my stove, heater and laundry all ran and Well…..this will not turn out well for everyone.

  7. I love these options and own a few prana pants. I do a lot of hiking and backpacking and polyester is important to maintain body temp regulation. I struggle with the backpacking and packing out, but the materials used aren’t environmentally friendly!

    1. I love wool for its antibacterial and antimicrobial properties, and I think Icebreaker looks like a pretty amazing company. I’ve been looking at ordering a shirt and trying it out.

  8. Another great option is a new brand Tala. It’s founded by a young girl boss and they have made sustainability their top priority. They use recycled materials, compostable tags and are very transparent about everything. They also focus on being inclusive by using different models of different sizes. I haven’t tried them out myself as I don’t need new workout clothes yet. But nevertheless I would recommend them. It’s such a cool brand (and affordable as well)!!

  9. My understanding is that even recycled synthetics generate microplastics in the wash. I certainly own my share of workout-wear made of synthetic and even recycled fabrics, but I’m leaning more and more toward eschewing synthetics altogether and searching out brands made entirely of natural, plant or animal-based (e.g., wool) fibers. Recycling is a good first step, but to my thinking it also justifies the production of yet more plastics. "Hey, it’s recyclable, so…"

  10. Thank you for the very informative roundup. I would also add FABSOUL® to the list, a new brand that focuses entirely on activewear made from natural, plant-based fabrics as synthetics (even recycled polyester) still shed microplastic that end up in the oceans. Their first leggings collection is made from Tencel which is high performing, naturally antibacterial, and super comfy. I’m wearing mine all the time to everything 🙂

  11. Hello, I do a lot of hiking and backpacking and polyester is important to maintain body temp regulation. I struggle with the backpacking and packing out, but the materials used aren’t environmentally friendly! Now finally I found this.

  12. Thanks for a very comprehensive list! I’m the co-founder of Weekendbee, an online store focusing only on sustainable sportswear and our aim is to make it easier to find different sustainable sportswear brands. We offer brands like Patagonia, Girlfriend Collective, Népra, prAna, OGNX, People Tree. Let me know if you would be interested in collaborating with us. Cheers!
