Hi there. The Get Home backs are smaller and stay in the cars—there are times my husband is driving one car and I’m driving another. Sometimes into the mountains. So I want the “get home” bag in there incase we get stuck or something happens. The Bug Outs are slightly more extensive and stay by the front door for the four of us if we had to bug out by vehicle or on foot. Then I figure if we went in the car the bags in there would just be extra in case we wanted to help someone etc.
