I think the cargo pants might be a partial solution. It would work good for stuff like the map, and maybe a thin first aid kit, but add very much weight or bulk, and with it moving as you walk, it gets real annoying real quick. The survival gear that I don't really need access to while walking could ride in my slash pockets. The waist belt blocks access, but if I need my emergency blanket, then I probably wouldn't have my pack on anymore anyways.
The Ribzwear pack is the best thing I've seen yet, Thanks for the link.
Carl, I know that the pack should be built sturdy to work well, but I'd like to avoid Molle if I can. Compared to a well designed dedicated setup designed for what I need, a Molle setup would add unnecessary weight. The problem that I was running into was finding a dedicated chest rig designed for camping, not carrying ammunition into battle.
So, assuming that the map, first aid kit, and any extra survival gear could be carried in cargo and slash pockets, and the camera and monocular could be carried in pouches on the backpack shoulder straps or waist belt, that leaves food, compass, GPS, knife, rain poncho, and handgun, and maybe some sort of "admin" pouch for mulitool, flashlight/headlamp, note paper, pen, ect. This stuff would need to be carried on my person, rather than the pack, and must be easily accessible with the pack on.
