Let's be clear, sustainability is chic - and any chance we can get to support eco-friendly fitness brands that are shaking up the often less-than-green activewear industry is one we are quick to pounce on.

And thankfully with the development of new materials made from innovative fibres like bamboo or repurposed plastic in abundance, it has truly never been easier.

Whether it's squat-proof leggings you're in the market for, tread-ready trainers or the cutest tennis kit to take to the court, there are sustainable brands out there to fit every need.

Now, the first rule of sustainability is to buy what is necessary. Instead of overhauling your entire wardrobe, we suggest swapping out your worn-out and weary favourites with these durable, planet-friendly labels.

Not sure where to start? Below are our editor-approved favourite brands and top picks to add to cart from all of them. It's time to get sweaty, sustainably.
