This line, buried deep in the article, is what completely boggles my mind:<p>> <i>We tell customers to wash their outerwear, regardless of whether it has PFAS or not, after every three to five significant uses and to re-waterproof every three to five washes.</i><p>Their <i>outerwear</i>? So we're not talking about inner layers here. All of them? <i>Every three to five uses??</i> I have jackets and coats that are decades old, in active (seasonal) use for the whole time, that I have <i>never</i> washed. Is this unusual? How would you even wash them? For some of them, it seems like just throwing them in a washing machine would damage the surface layers, make the lining lumpy, shrink them, or do some other problematic thing to them.
