Fabrics That Could Be Toxic and What To Replace Them With

A raincoat wouldn’t be handy if it weren’t able to repel water. The same process that lets Gore-Tex and similar fabrics shed water also helps other clothing resist stains. Unfortunately, this process uses per- and polyfluoroalkyl substances (PFAs), which can be toxic to humans. These “forever chemicals” can last in the environment for thousands of years and lead to kidney cancer, testicular cancer, liver damage, and even developmental issues.
