Hey /out/

I've been looking for a "bug out bag" I guess, I don't really think there will be some kind of happening but I think it would be fun to make one and do innawoods type stuff with it. Problem is I don't know what backpack to get, there's so many different manufacturers. Drago has seemed pretty good so far. What does /out/ reccomend? What are notable qualities to look for in a good survival bag?
