Those are different kits and the reason the votes are distributed is due to different perceptions.

IMO a Bug-Out-Bag is fairly lightweight and is oriented on providing what you need to get to a bug-out location. If you don't have a place to go, why bug-out? A survival bag will mean different things to different people and is situation dependent. Is it designed to sustain you for 72 hours or months? Is it summer, winter or sometime in between?

I'm not big into bugging out with a pack on my back. My Get-Home-Bag weighs less than 15#. My survival kit is truck based and carries a lot more than wildman would want to carry. As I recall Wildman's kit weighs what it does because he may be looking at a long walk. Where I live walking out is not an option.
