Depth, front to back. As much as I want one, there are things more important to use money on at the moment.
Oh in that case - yes the one you mentioned is WIDER, and I think overall larger (height too). I could never carry that + the pack talk about stress on the back.
That looks a heckuva lot like a Maxpedition Baby Condor...am I right? I've got one myself, but in khaki. I also use mine as a BOB/camping/hiking pack, works really well.
I have to ask though, how did you manage to attach your knife and sheath to the side of the pack? I don't see any attachment points, did you sew it on?
No, this is bigger. Maxpedition Vulture II Pictured:
Here KNife connects to the side attachment points... <img src="/images/graemlins/smile.gif" alt="" /> knife spot is perfect.
