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

There's something to be said for keeping things simple. PACT uses 100 percent organic cotton and not much else; this sports bra, for example, is 82 percent cotton and eight percent elastane (similar to Spandex). Plus, every product tells you how much water was saved while making it, since producing organic cotton requires less water than conventional. And that cotton makes things light, comfortable, and cozy to wear.
