Thanks for posting this.
A more vertically designed shoulder bag seems like a great solution to quick camera storage if your back is already dedicated to a hiking pack/camelback.
I have been looking all over for a tough, vertical, messenger-type camera bag, not a messenger that I have to frankenstein and end up paying more in the long run. And not something so wide and bulky that it's going to be bumping into my backpack.
I'm ordering one, asap.
(Now it just comes down to color: Black, Olive or Sand...)
