You want the Batignolles Horizontal, but...

I had the bh for a week until it tipped over and all of my stuff fell out. I love the bag and its shape but in my case since I used it as a workbag I needed to have something more secure.
 
I'm accustomed to carrying totes to work that do not have a zipper, so the BH not having a zipper would not bother me at all...but I have to admit that I would have to be extra careful with the open top while I'm out shopping or something...
