Many companies that outfit us for yoga and running are often the most enlightened about sustainability, presumably because they have a personal stake in preserving the spaces we need to refresh and unwind. That’s good news for us because it means we have lots of choices when it comes to ethical and eco-friendly activewear.

What to look for in ethical and sustainable activewear

Natural fibers: You can find brands made stylishly with a blend of organic cotton or hemp and a little bit of synthetic fiber for stretch.  Organic natural fibers are not only better for the environment, they release odor better than synthetics. Look for merino especially, which is so sweat-wicking and odor-fighting that you don’t have to wash it after you exercise in it. Just hang it up to air out.

Recycled synthetics: If you need high-performance synthetics, go for recycled, which is super easy to find. And don’t worry: recycled plastic clothing is not inherently toxic, no matter what the wellness influencers say.

Performance: It probably goes without saying, but you want activewear that’s actually high-quality so you can wear it and wash it over and over again for years. Customer reviews are a great place to check for how well something fits and holds up after a month’s worth of gym sessions.

Non-toxic dyes and finishes: The dyes used to color your standard pair of leggings aren’t good for the earth—or you. Look for natural and/or non-toxic alternatives and certifications like OEKO-TEX. Also try to steer clear of toxic durable water repellents that are often on outdoor gear.

Fair labor and transparency: As with everything you buy, check for fair labor practices. Look for brands that prioritize transparency (do they tell you where their apparel is made?) and certifications like Fair Trade and SA8000.

Arms of Andes

Arms of Andes is the only activewear brand we’ve found so far that uses alpaca. The brand was started by a brother and a sister who were brought up in the U.S. in a Peruvian household, and their trips to Peru eventually inspired them to start a sustainable apparel brand using alpaca wool. Because of the way alpacas have evolved to live in such high altitudes, alpaca wool is not only completely ethical and biodegradable, but it’s also high-performing when made into clothing. Alpaca wool easily adapts to changes in temperatures, which means it’s great for hiking and other outdoor adventures. It’s also naturally odor-resistant, moisture-wicking, wind-resistant, and more. The wool Arms of Andes uses isn’t just any wool​ ​​ ​it’s Royal Wool, the finest and most luxurious—and only about 1% of exported Alpaca wool is royal. This is why Arms of Andes clothing feels so much softer than other wool clothing you might have tried.


Yoga Democracy

Shop Yoga Democracy for tops, shorts, and leggings made from recycled polyester and nylon. It uses a low-energy, zero-water process, non-toxic dyes, and donates 10% of its net profit to environmental causes worldwide. Yoga Democracy takes every scrap of material that passes through its shop and turns it into something useful. Its garments are sewn in California by responsible fabric manufacturers. Just make sure to order ahead, as many of its products are made to order and have a few weeks lead time.

Don’t forget to capture your microfibers!

Many of the brands above use recycled materials, which is awesome because it means less plastic clogging up our waterways and landfills and less non-renewable virgin materials used. But, you still have the problem of microfibers that slowly break off and enter our streams and oceans when you wash your clothes. To cut down on the amount of microfibers that shed off your activewear and into the water, try using one of these tools:

The Microfiber Filter

If you have your own washing machine, grab this Microfiber Filter from Girlfriend Collective that easily installs onto your washing machine and can capture microfibers from any of your synthetic laundry. It’s only $45.

Guppyfriend Washing Bag

If you don’t have your own washer, the Guppyfriend Washing Bag is a great option as well that can be used at the laundromat or taken with you for travel. Put your synthetics right in the bag, which will filter out microfibers. It’s only $30.
