Now when I fill the pack up like this, it seems that the helmet on the top making the bulge would hit your head. I can honestly say that's never happened. I have full mobility when the pack is filled to its capacity, and I have actually fit another set of BD Camalots .1-3 on top of what you see. Seriously an awesome pack!
