I don't seem to have a lot of success, with my question.

I guess/hope it's not a military secret ("how to use a backpack - for your eyes only").

So, maybe, my question is not correctly formulated..
Let's try this way : are those backpacks (Maxpedition Condors) specifically designed to be used in conjonction with another pack ( like Devildog or Proteus Versipack), so it can "sit" on it ???

Or ... I really need some lessons :"how to use a backpack - 101" !!! <img src="/images/graemlins/grin.gif" alt="" />
