I have a variety of packs, from the Large Alice, a Large Kelty, to daypacks and buttpacks. Finding room for the stuff is not a problem.

But how much is too much, weight wise. I'm not the 22 y/o who carred the 100 lb+ radio ruck in Alaska anymore. I have tried to pare the packs into manageable sizes/weights so that if we have to bug out on foot - the final option as far as I am concerned - each pack would be under 30 lbs w/o water, about 35 with. This would give us about a gallon of water apiece, 4 days food, materials to build shelter/fire, extra clothes and socks, mess gear, water purification, and a toilet kit. There is some dupication, but that's for the good.

What would your BOB max weight ideally be if you were on foot?
