Au Contraire, the REI Traverse may be ideal if you need to move fast. Some guys load up a big backpack and call it a BOB and then they throw it in their car and drive. I have a couple large duffel bags in my car, my Bug-Out-Bag is a Camelback Mule and is designed to sustain me while I'm moving fast. A BOB is not a 72 hour kit, it's a bag designed to have enough supplies to get you to wherever you are bugging out to. Don't have a destination?? Then stay home and Bug In, no bag required.
