6 Sustainable + Ethical Sportswear Brands - Zero Waste Nest

7 Sustainable + Ethical Sportswear Brands

Fashion can be quite a wasteful industry, that’s big news for no one. That’s why I strongly recommend buying your clothes second-hand if you have the chance to have thrift stores near you, or if you have access to websites or apps that connect you with people selling their clothes. Another great option is to rent your clothes but that does not really apply for activewear.

I personally buy all my clothes second-hand, except for underwear (duhh) and activewear. And that’s simply because I can’t seem to find precisely what I need second-hand.

Clothing has the 4th largest environmental impact1 after housing, transport and food.
