Very nice system. I've been trying (unsuccessfully) to add a pouch onto my rucksack that could hold some emergency equipment. The idea is that should i be in a life threating situation (bush fire, flash flood?) or other situation where i cannot take my backpack with me, i'd be able to easily grab this 'emergeny pouch', and have a much better chance of coming out of the situation alive. the pouch would be a large moon bag (fanny pack?), or a hip pack, so i could carry it around my waste. I still havn't got it right though.
