I just bought some new underwear from Marks & Spencer in the UK which has their "Cool & Fresh" treatment. I haven't worn it yet but this thread is putting me off. M&S publish a Manufacturing Restricted Substances List [1] for their suppliers, which seems to ban the use of all per- and poly-fluorinated chemicals in the manufacture of textiles for them. Either I'm misunderstanding, or some of these underwear treatments don't involve PFAs. Who knows what they use instead?
