There was this fantastic bag I saw in the men's section of YSL this past AW. It was a black leather sling bag with a mombassa horn on one side. I also really like ther Hermes Vespa.
I love my LV Musettes. I have the large Musette and the smaller Salsa. If you buy the smaller Salsa, be sure to get the long strap. They are both very comfortable to carry.
