Launch into your fitness routine while looking and feeling good with our ultimate roundup of more ethical and sustainable activewear.
Sweat it out in more sustainable style
Whether you’re looking to start a new training regime or you’re deep in the grind of your exercise routine, good clothes can help you stay focused and comfortable.
Activewear is traditionally made with harmful materials like virgin polyester and nylon, which require hefty chemicals to produce and continue polluting by shedding microplastics during use and packing landfills at end of life. Lower-impact activewear might be made from materials like recycled polyester, organic cotton, bamboo viscose, or hemp, which are better alternatives to the new, plastic-based fabrics that still flood so much of the market in fast fashion listings around the globe.
The following brands are either dedicated to making activewear or have some great options within their ranges, helping you keep the motivation high and your impact lower. Each of these responsible activewear brands is rated “Good” or “Great”, so you can exercise easy knowing they’re committed to reducing their impact on people, the planet, and animals. We also recommend searching for secondhand options and checking your local charity or thrift shops, which often have great options at much lower prices than new. With that, let’s jump in.
