I generally tuck my mason jar bear canister under my arm like a football, and go sans hip belt.
If I find I need more support, I use my catheter as a make shift belt.
If I need even more support, I use the lean back wall of my tent to beef up my pack frame.
For even more frame, I put my SAW vertically against my back like a stay.
If I need more support than that I inflate my back country lazy boy to stiffen the pack to the max.
If I don't have a unflatable lazy boy, or, saw, or catheter, I just bring a pack with a hip belt.
