What I packed on my month-long trip through southeast Asia
It can certainly be trimmed down further. I have more clothes than are really necessary. I also had a hand towel when I started out in case a place I was staying at didn't provide one. I don't like using my own towel though, because they take a long time to dry and packing wet things in your bag encourages bad smells and mold. I lost it though, so now if I need a towel in a pinch, I use the sarongs.
