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.
If you’re an eco-conscious consumer like me, you’ll be looking for sustainable running clothes over fast fashion options.
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.

What to look for when choosing running clothes?
According to Runners Need, the most important things to look for when choosing running clothes is to find comfortable, sweat-wicking, quick-drying, and breathable clothing which will help to wick away any sweat and keep your temperature regulated and keep you running comfortably.
It’s always a good idea to make sure you wear clothing that’s hi-viz if you’re running at night or when its dark outside.
