If a female may join the discussion, the BOB is one of my favorite topics. We also use the dual BOB method. I personally use the Maxpedition Proteus and the old Baby Condor backpack. The proteus goes wherever I go. I also agree with the importance of knives and firemaking. I keep multiples of each, both on my person and in each bag. I like the idea of the braided paracord on the keychain... I will have to add that. Thanks for the suggestion.
