The OP is correct. There are several testimonies online from motorcycle riders who have worn polyester-type materials that have melted into their skin. From what I have read Under Armour is the culprit.

If you want super-thin, pajama-like leathers, find some Kushitanis.

Polymers have low thermal conductivity (like our skin), and so they heat up and melt rapidly. That's why you do not powdercoat headers and exhaust manifolds. Yes, yes, there are some powdercoats that can go up to 400+ degrees and the technology is rapidly changing, but do your homework.

This is from WebBikeWorld:

"So what's so special about Under Armour? I honestly don't believe they use any double-naught, double-special-secret fabrics or anything like that, although I think they'd like you to believe so. The fancifully-named "PolyArmour" material seems to be a type of poly-something-or-other -- polypropylene maybe? "
