Also known as a survival kit, an emergency kit, or a 72-hour kit, it’s a portable kit, typically a back pack, that contains items one would need to survive for some period (usually 72 hours or longer) when evacuating from a disaster.
The term “bug-out bag” is related to, and possibly derived from, the “bail-out bag” emergency kit many military aviators carry. In the United States, the term refers to the Korean War practice of the U.S. Army designating alternate defensive positions, in the event that the units had to displace. They were directed to “bug out” when being overrun was imminent. The concept passed into wide usage among other military and law enforcement personnel, though the “bail-out bag” is as likely to include emergency gear for going into an emergency situation as for escaping an emergency.
Other names for such a bag are a BOB, 72-hour kit, a grab bag, a battle box, a Personal Emergency Relocation Kit (PERK), a go bag, a GOOD bag (Get Out Of Dodge), or INCH bag (I’m Never Coming Home).
