This literally means a condom disguise for Halloween or a costume party.

Well, IMO 'sweaty' indicates latex, not just some costume.

You can try to guess what this really means

Yes, it’s a latex costume and “sweaty” doesn’t mean that it’s full of sweat - it means that you will get sweaty if you put it on.

I don't mean to argue, but I think one can't survive in such costume if it's made of latex.

I think it's fabric

Sometimes they’re made of plastic, sometimes (faux) latex, sometimes polyester - they’re quite popular costumes here for some reason. Regardless of the material, since they cover your entire body, they’re considered “sweaty.”

OK, you know better. I've never seen real them.
