Hey guys, I'm going to Tokyo in 2 weeks' time, and I'm looking for a nice camera sling bag or backpack, preferable those leather or vintage-looking kind, to use while walking on the streets. I'm bringing my Crumpler Karachi Outpost over but I don't want to carry it on the streets 'cause it's too big and makes me stand out. It'd be great if anyone knows of bags which I can get in Japan too, thanks!
