Domke did a "Next Generation" thing about ten years ago where they remixed their classic bag designs and ended up with a pretty cool line of updated products which they then cancelled and never spoke of ever again. The Crosstown Courier is one of those, about the size of an F-5XC, except with a more versatile removable divider system, an easier-to-access top zipper, and more front pocket storage, among other things. It's a nice little shoulder bag with modern features and classic understated Domke styling. Interior dimensions are approximately 10x24x19cm.
