A bug-out bag is a portable kit that contains the items one would require to survive for seventy two hours when evacuating from a disaster. It is also known as a 72-hour kit, a grab bag, or a battle box. The focus is on evacuation, rather than long-term survival, distinguishing it from a survival kit, boating or aviation emergency kit, or a fixed-site disaster supplies kit. Bug-out bags are popular in the survivalist community. The term is related to, and possibly derived from, the ‘bail-out bag’ emergency kit many military aviators carry.
