Activewear is an indispensable part of even the most basic wardrobes. A pair of leggings or biker shorts are often among the most-used items in our closet. Their stretchy, body-hugging characteristics plus dual functionality as both day wear and workout gear have us wearing them a lot.

However, activewear can be a blind spot when trying to shop more sustainably. We tend to put a spotlight on the mega fast fashion brands like Zara, H&M, and SHEIN when we think of clothing terrible for the environment, but forget that 90% of the leggings and sports bras in the market are made almost entirely out of petroleum aka polyester. And the big brands like Adidas, Nike, Lululemon and Athleta churn out this micro-plastic shedding crap 24/7 –spending more money on marketing than on changing their ways to be more planet friendly.

“What about leggings made from recycled plastic bottles? Aren’t they sustainable?”

-most people

Not exactly! In fact, a recent article by Business of Fashion stated that it’s better for plastic bottles to be recycled as plastic bottles than into leggings. Why? Because bottles can be continuously recycled –as leggings, their next stop is a landfill.

So, unfortunately, they remain more of a marketing tactic than an environmental solution. After all, plastic is still coated in every fiber strand of the fabric. That means once your favorite green-label yoga pants reach the end of their usable life, they won’t be in the minute 1% of clothes get recycled. And NOT-SO-FUN fact: It takes 450 years for PET to decompose fully, not to mention the release of micro-plastic into the ocean, intoxicating marine wildlife and posing carcinogenic threats to humans ourselves.

Instead, let’s aim for low-to-none synthetics in our activewear. Whether you live in leggings or prefer loose and flowing yoga pants, there exist planet friendly options.

A few other things to look for when shopping for eco-friendly Plastic Free activewear

  • Bluesign or Okeo-Tex certification. These both look for harmful chemicals in textiles and these labels guarantee you won’t find them.
  • Natural fibers like hemp, cotton and Tencel. Tencel is a plant-based natural fiber with a high water absorption rate (50% more than cotton!), making it ideal for activewear. Merino wool is also a great option –as long as the brand is working with ethical farms.
  • For performance know that brands will likely have a small amount of spandex. We look for 5-10%.
  • It goes without saying but make sure you love the item, it fits well and you plan on owning it for a long time. Because the longest kept items are ultimately the most sustainable.
