Be Kind to Your Body and the World With These 12 Eco-Friendly Activewear Brands

Products from Swedish brand Casall swap polyester for polyamide. Doesn't sound like a big deal? It kind of is: polyamide is made from smooth fibers, which make it harder for bacteria to grow. This way, the brand's clothes can skip antibacterial treatments that are rough on your health and the environment's. Plus, the brand's Conscious Choice collection is made with recycled materials, like fishing nets; this low-impact bra, for instance, is actually made from recycled yarns.
