Whether you’ve been an avid runner for years or are just getting started, one thing is certain: you need comfortable clothes that support you and let your body breathe.

Unfortunately, exercise and running gear isn’t usually available second hand due to the wear it goes through, so it means we have to buy new items. However, there’s still a way to shop for running clothes sustainably, and that’s by supporting brands using their platform to make a positive change.

In this guide, we’ve found some of the best brands making sustainable running clothes and sustainable activewear, using eco-friendly materials without compromising on performance.

Let’s jump in.
