The closest I've seen in terms of a small minimalist hobo bag (for guys, anyway) is this Guidi bag, but even it has its downsides. I think it's unlined, and the dye leaches out onto whatever you're carrying in it. Also, there's nothing securing the end of the strap, so it's just dangling there if you want to have the strap tighter. It's a decent-looking bag, but not that practical for those reasons. Haven't seen a canvas equivalent anywhere, either. The Noctex lung bag doesn't have the same issues as the Guidi bag, but it's a bit larger than I'd ideally like.
