The outdoor industry continues to grapple with the thorny problem of forever chemicals, like PFAs and PFCs (PFCs are technically PFAs, too, the terms can be confusing), that are often used to treat performance fabrics for things like water repellency. If a jacket, for example, has been treated with PFAs, those chemicals can be released into water systems as they’re washed. Or eventually, the clothes might end up in a landfill, and rainwater captures the PFAs and eventually washes them into rivers, lakes, or oceans.
