It is strange! It's a recent thing in the US, yes. Probably in the past 4-5 years nearly all major brands put some sort of special chemical that gives it 'moisture wicking' (usually in partnership with Dow or 3M).
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?
