>Well, to be honest with you, I don't really know how to tell him.
To both you and abawany: maybe just send a polite, anonymous email (make a one time use gmail or something)? Like a personal version of the public service whistleblower, this is the sort of situation that seems like a good fit. A simple "Hey, I see you fairly regularly and..." type of thing, that they're a nice person and you're worried they might not notice this and don't want them to be embarrassed.
I do agree that a (perceived) lack of personal hygiene can hamper people in subtle ways socially and in turn professionally, and it's possible that they could never realize why. If they're a decent enough person that's a real shame, and a quick equivalent of "Your fly is unzipped" could be a real benefit long term.
