Their findings? Eco-conscious activewear is surging in popularity and is one of the biggest trends set to dominate the industry in 2020 and beyond.

Luckily, there is a plethora of brands both established and emerging in the space that are here to cater to the boom in interest. Ready to sweat consciously? Here are the brands you should know about:
