Our editors have picked out the best activewear brands using lower impact materials to make polyester-free tights, tops, and bras you’ll love to sweat in.

Leaving polyester at the gym door

For the avid gym-goer, yogi, runner, or sportsperson, high quality activewear that is both breathable and moisture-wicking is essential. But unfortunately, many of the most popular activewear brands are still using polyester to achieve those characteristics. Polyester is the most notorious and overused plastic-based fibre on the market today, and it might even be exposing shoppers to toxic BPA.

While polyester has some desirable qualities for activewear—since it is stretchy and long-lasting—but its impact on the environment is catastrophic, including shedding harmful microplastics into the air and waterways, and taking centuries to break down in landfill.

But it is possible to avoid polyester in activewear, and our editors have selected products from top-rated brands doing exactly that. All of the brands below use lower-impact materials like organic cotton and lyocell to form the majority of their garments, but you’ll notice almost all of them do contain some level of elastane. That’s because as yet there is no perfect solution to hardy activewear that can stand the tests of time and trials without some stretchy component.

So while elastane isn’t a lower-impact material, the impact of your shopping choice is still reduced by opting for a garment made from a low percentage of a plastic-based synthetic like elastane, compared with a new pair of virgin polyester or nylon leggings from a brand like Lululemon that is doing little for people, the planet, and animals in production.

The more responsibly created activewear you’ll find here is a great alternative for those who don’t want to sweat it out in polyester—recycled or not—for the benefit of their bodies and the planet.
