Strange listing, and if the purpose is to impress, he fails miserably.

If he is staying in hotels, why does he need a quick-dry towel? And if he isn't staying in hotels, but rather hostels, where are his flip-flops? Laundry detergent? Plastic cutlery?

And no plug adaptors? He must not leave North America much.

I suspect that his "toiletry kit" is probably a catch-all for a whole bunch of stuff.

But, hey, if all you do is "travel" in a repetitive pattern, don't want to actually get out and see or do anything, and have no spares to speak of, pretty much anyone can pack light.
