went through my "bag" earlier this year as it was way too heavy for a GHB...it is based on a nylon poncho and mosquito netting which is a little heavy to begin with (it is wet down here most of the year)..I took out the heavier 72 hour equipment..Swiss stove and Sterno, machete, Vic Swiss tool, SRK, spare shoes.... replaced tins of meat with pouches etc...but placed the removed equipment in a gym style bag that resides alongside the "bag" which gives me an option
