sustainable activewear green is the new black

2020 was a tough year, but one of the many things we learnt is that moving our bodies has never felt so good – even if we had to improvise a little (yoga in the kitchen, anyone?). It’s fair to say that we no longer see our exercise clothes as just gear for a weekly class, but as physical and emotional comfort, protection, and support in this ‘new normal’ way of life. 

No matter what the new year brings, we’re sure that our need to move, stretch, and support our bodies and brains won’t change. Cue our cool, comprehensive compilation of the best ethical and sustainable activewear brands out there. From second-hand co-ops to black-owned businesses, from body-positive brands to sustainable superstars, our guide has got you (and your endorphins) covered.

sustainable activewear outfyt


Ethics: Sustainable fabrics, ethical manufacturing, fair working conditions, zero single-use plastic, eco-friendly packaging

Collections: Womenswear

Origins: Singapore – born, Italy – fabrics, Indonesia – made in

Thanks to the Swedish roots of its founder, Outfyt channels the minimalist vibes of Scandi-chic. Think clean, simple lines in bold block colours that flatter. The functional design of its capsule collection means each piece can be worn in multiple ways, providing extra bang for your buck. All that plus sustainability is intrinsically woven into the DNA of the brand. It uses eco-friendly fabrics like ECONYL regenerated nylon (made by recovering nylon waste like fishing nets from the ocean and carpets destined for landfill) to create its signature looks. It has also removed all single-use plastics from its supply chain, and it champions ethical manufacturing in Indonesia through ensuring fair working conditions and pay for employees.

sustainable activewear the giving movement

The Giving Movement

Ethics: Sustainable fabrics, ethical manufacturing, fair working conditions, giving back, eco-friendly packaging

Collections: Menswear, womenswear, modest collection, accessories

Origins: UAE – designed and made

Not gonna lie; we’re a little obsessed with the street athleisure vibes that The Giving Movement radiates. You might have twigged thanks to the name, but The Giving Movement places giving at the core of its business. For every item you purchase, it will donate $4 to its partner charities. Through its approach to conscious consumerism, it aims to create products that don’t harm the planet further while also helping change the lives of those who need it most. It goes without saying that its entire line is created using sustainable fabrics like recycled nylon and biodegradable bamboo pulp. The broad collection features everything from joggers, hoodies, and sweatshirts, to shorts, tops, and sports bras. And as it’s created in the UAE, there’s even a modest collection.

It was the combination of her love of yoga and a desire to share her West African heritage that sparked Ncheta Dasilva to create Zola Eve. The British brand, which features yoga pieces in vibrant, Ankara-inspired prints, promotes the message of being who you are. It uses real women as its models, avoids photoshopping, and creates clothing that both supports and flatters women of all sizes. Zola Eve uses recycled materials, which also happen to be high-performance and ideal for exercise. Every garment is designed and produced in the UK, made by a social enterprise who eschew waste, offer training to local workers, and are all about fair wages.

Hoya Kerry sustainable activewear

Ethics: Sustainable fabrics, circularity, low waste, tree planting

Collections: Womenswear, accessories

Origins: Hong Kong – born, China – made

Hong Kong-based Hoya Kerry takes its name from the hoya kerii, a heart-shaped plant that is a symbol of love. And it’s this ethos of love – for the planet, for yourself, and for exercise – that ripples through the brand. Its collection comprises tops, bottoms, sports bras, and accessories, providing everything you need to get your sweat on. To create the colourful Hoya Kerry look, it uses recycled polyester made out of ocean plastic waste. For every order it receives, Hoya Kerry plants a tree. In effect, it’s removing waste and replacing with nature, and we’re totally on board with this circular philosophy.

You know how some brands say they are transparent, but don’t walk the talk? Well, Girlfriend Collective provides so much information surrounding its products, fabrics, supply chains, ethics, that some might say it’s TMI. But not us, we love knowing everything there is to know about a brand, which is why we’re huge fans of Girlfriend Collective. Aside from its excellent sustainability creds (sustainable fabrics, social accountability, ethical workplaces, recycling scheme, eco-friendly dyes, we could go on…), did we mention it creates easy-to-wear designs that suit all body shapes? Its body-positive, female empowerment messaging is a breath of fresh air and we’re here for it.

Ethics: Sustainable materials, pre-loved, giving back, community power, eco-friendly packaging

Collections: Womenswear, menswear, childrenswear, accessories

Origins: USA – Born, Various – made

We’re not exaggerating when we say that REI has everything for outdoor pursuits and athletic activities. The retailer covers all areas, from skiwear to running gear. Best of all, it sells both new and used items and focuses on sourcing sustainable materials like organic cotton and cellulosic fibres from trees. REI is actually a co-op, which means it puts purpose above profit. It supports its members and fellow lovers of outdoor pursuits; 70% of the annual profits are invested back into the outdoor community. REI really practises what it preaches; in 2019 it urged its employees and members to opt-out of Black Friday, and to sign up to the Opt To Act plan, which offers small steps towards reducing environmental impact.

Wolven’s tagline is spot on; they do make sustainability sexy. Their pieces are colourful, inspiring, and slightly spiritual – we’re talking jazzy patterns like Mandala, Chakra, and Reverie. You can find the usual active must-haves, but there are also a few unicorns in the gang, like stretchy, seventies-style bell bottoms (which they recommend for roller skating. Yes, this is amazing) and a reversible four-way bra top. Now onto their credentials: they make activewear from recycled bottles (27 in one pair of leggings!), ensure shipments are carbon-neutral, offset their own carbon emissions, support rainforest conservation, celebrate different shapes and sizes, use carbon neutral fabrics (sustainably harvested cellulose fibre) and certified recycled fabrics (OEKO-Tex), and package their goods in hemp and recycled packaging. Phew! Got all that?

It wouldn’t be a complete activewear guide without the inclusion of gentle giant, Patagonia. The California-based brand, known for its outdoor wear, is passionate about caring for the planet. As well as creating new items using recycled materials, it also sells ‘Worn Wear’. Really, when it comes to taking action for the planet, what isn’t the brand doing? It pays a self-imposed Earth tax (1% For The Planet) which supports environmental non-profits, discourages customers from buying too many of its items (for real), and runs Patagonia Action Works which allows customers to connect with grassroots environmental groups and take action in their area. Also, in the Activism section on its website, the brand offers tons of insightful articles on environmental conflicts and the projects the company is involved in.
