Activewear has wriggled into our wardrobes to occupy serious shelf space. However, for a long time workout wear has been made primarily from synthetic material like polyester, which isn’t biodegradable and is produced using hazardous chemicals. What’s more, with each wash, it sheds microplastic fibers that find their way into our water and soil (more on that below).

Today, several brands are committed to making active gear with eco-consciousness at the forefront. For the shortlist, we’ve considered activewear that is comfy, ethically made, and environmentally friendly, cutting across price points and covering a wide range of low-impact materials such as organic cotton, Tencel lyocell (made from wood pulp fiber), bamboo, and more. However, it's worth noting that for stretch and fit, almost all workout apparel still contains some proportion of synthetic materials such as elastane.

So, whether you’re looking for moisture-wicking crop tops or slouchy sweatshirts, we've put together a list of the best sustainable workout clothes.

Best Overall: Organic Basics

Breaking into a sweat has never looked so good than in Adidas by Stella McCartney’s latest drop, the bling-y FW 21 Stellashine. The high-wattage collection elevates activewear with oodles of glamour, shimmer, and texture, without compromising on action.

The crops, tights, jackets, and shoes feature tech developed by Adidas. These technical materials include moisture-wicking "Aeroready" fabric and performance-enhancing "Boost" footwear cushioning. Designed using recycled materials, including recycled polyester, the Stellashine collection is solid enough for the track and sleek enough for the bar.

Best Sweatpants and Sweatshirts: Outerknown Apparel

Outerknown Evolution Hooded Jacket


Outerknown’s stylish Sur French terry sweats are made from organic cotton and hemp. Durable and breathable, it's comfort wear to loll about in or do some heavy-duty squats. The laidback sustainable label founded by professional surfer Kelly Slater is Fair Labor Association accredited and 90 percent of the fibers used by the brand are organic, recycled, or regenerated.

The sweatpants have a flattering tapered silhouette, an elastic waistband, and even a zip back pocket, but come in limited shades. On the other hand, the snuggly sweatshirts come in a gaggle of calming colors, including Henna, Marigold, and Cosmo. Shoppers find the duo comfy yet rugged, scoring high on both counts of sloth-worthiness and sportiness.

Most of the garments are designed for women, but there's also a small collection of unisex and toddler items.

What to Look for in Sustainable Workout Clothes

Check the Materials

Conventional activewear is made from synthetic materials such as polyester, nylon, and spandex and often uses dyes that can harm the environment. For more eco-friendly clothes, you can choose among many alternative fabrics, such as organic cotton, econyl, hemp, Tencel, bamboo, and material made from recycled plastic (though for stretchiness there will be synthetic materials blended in).

Trusted Certifications

Pick ethically made environmentally conscious and skin safe activewear. Check for globally recognized third-party certifications such as OEKO-TEX, Global Organic Textile Standard (GOTS), Fair Trade, and B-Corporation.

Comfort, Use, and Fit

Ask relevant questions to buy gear that you’ll actually wear, rather than sexy but impractical sportswear that’s relegated to the far end of your closet: Would loose-fitting (or tight-fitting clothes) make you feel more comfortable? Would those cutesy shorts chafe? Would you be exercising indoors or outdoors? Would compression gear work better for you? Do you need gear with moisture-wicking properties? Are you working out in summer or winter?


How can I make my workout clothes last longer?

Keep your activewear clean and stretch its life (not the elastic) with these handy tips. After a sweat sesh, you’d be tempted to dump the damp gym wear in the wash. But air-drying them first makes them easier to clean. If they’re a tad stinky and awash with stains, soak them in a dash of vinegar mixed with water before washing. Turn the clothes inside out before the cold spin (to protect the stretch and prevent sagging). Nix the dryer and let them air.

How can I avoid contributing to the micro-plastic pollution?

Your comfy synthetic activewear has a downside to it: Tiny plastic microfibers that shed each time the gear is worn and washed. These tiny particles that shed off from clothes and other stuff are responsible for a whopping 35 percent of the plastic polluting the oceans, according to Ocean Clean Wash. Here’s how you can minimize your impact:

  • Optimize how you wash: Fill up your washing machine to reduce friction between clothes. Opt for a natural liquid detergent and wash at cool temperatures on shorter cycles.
  • Invest in a microfiber filter: These bulky workhorses attach to a washing machine and imprison fibers before they can wriggle their way into the water stream and ocean. The filters need to be cleaned and the waste disposed of carefully after every few washes. Check out Girlfriend Collective’s The Microfiber Filter (view on that’s affordable and accessible, and Filtrol’s sturdy filter (view on which claims to have a catch rate of 89 percent.
  • Minimize synthetic fabrics when possible: It's not always the most practical or comfortable to work out in cotton clothes, but when you can swing it, know that opting for garments made from natural fibers is the best way to avoid adding to the microfiber problem from laundry.
