Actually, there are differences, most notably in the suspension, from what I understand. <br><br>The CFP-90 is concentional internal frame, with the de riguer detachable "daypack" that makes a great 24-hour pack. It rides on shoulder straps and a belt.<br><br>The big USMC MOLLE pack is, from what I can find, is intended to be suspended from thier new LBV via some fancy voodoo interface plate. Now I could be completely wrong here, and if anyone can shed some light on it, please do. What I do know is that it looks like there is a semi-external frame that extends ub, behind the head. OK, so it can be easily used as an improvised head imobilizer, but it looks like it is too high and to rigid to be used in a combat situation with a helmet in a prone position (which appears typical of the military R&D people who came up with the reg that you can't have a spork in an MRE becuase the bag might be punctured by the tines if run over by an armoured vehilce). But that's just my opinion based off of having seen pictures of it.
