I've been and got myself a canoe bag and I've been playing with it. I've packed my bergan using a 100litre bag and filled it right up and I'm bloody exhausted. The thing would crumple at the bottom which meant I couldn't fit everything I wanted to until after I fought it for half an hour and started to cry. And then it just seems like a bad idea for a bug out, it seemed to take a lot more effort to get stuff in there. Do they tend to give a bit after a while because mines pretty stiff? Are they worth this seeming extra hassle? I don't want to be desperately trying to stuff my doss bag in there at zero dark thirty in the rain with exercise claw after a bug out.
