Thank you to the reviewer who listed the correct dimensions.  Had I read it before I would have bought this one first instead of wasting money on the other Baggallini zipper bag.  It wasn't bad, but this is much better for me.  It is easier to reach into, has more pockets, and thankfully two of them on the inside do not go all the way to the bottom of the bag.  The strap is wider and softer than the other bag.  It's not as dressy but comfort is more important to me.
I now own quite a few Baggallini items, including the matching messenger bag which I can slip this right into when I go where I need more "stuff".
