What all do you have that you're trying to organize? I'm just trying to picture what someone could take hunting that would require more organization than a standard "dump" pack and a pocket or 2??
I have a pullout that serves as a "kill kit". Everything I'll need to dress and get the animal ready for the pack or drag out. Have a bag for food, and one for first aid/just in case type stuff. That's about it! Bags for meat, clothes, pad/bag and everything else is packed in the main bag. Binos, rangefinder, nalgene, gloves, light, and a snack are all in the lid or external pouch.
I never saw the need to have my pack up the tree with me. Easy enough to take just the lid or, put what I need in my pockets and start climbing.
Just curious here, no offense intended at all. I just don't get where much organization would be needed???
