The Bug-Out Bag & 72-Hour Kit Guide
Sometimes the safest choice is to leave. Wildfires, floods, chemical spills, and fast-moving storms can force an evacuation with little warning, and when that happens you do not want to be packing under pressure. A bug-out bag — also called a 72-hour kit or go-bag — is a pre-packed bag that lets you walk out the door in minutes with everything you need to be self-sufficient for three days. Here is how to build one that is genuinely useful, not just a pile of gear.
What a bug-out bag is for
The goal is simple: 72 hours of self-sufficiency away from home. That is the window that covers most evacuations until you reach a shelter, a relative’s home, or services are restored. The bag is not a survival-in-the-wilderness fantasy kit; it is a practical grab-and-go that keeps your family safe, hydrated, fed, and able to communicate while you are displaced.
The core checklist
Water
Pack at least three liters of water per person to start, plus a compact way to purify more — a filter straw or purification tablets. Water is heavy, so the ability to refill safely matters as much as what you carry. (See our water purification guide.)
Food
Choose lightweight, no-cook, calorie-dense foods: energy bars, jerky, nut butters, trail mix, and a few comfort items. You want three days of eating that needs no preparation.
Shelter and warmth
Include an emergency blanket or bivvy, a poncho or rain gear, and a change of weather-appropriate clothing. Exposure is a real danger in an evacuation, so plan for staying warm and dry.
Light and power
Pack a headlamp or flashlight with spare batteries and a charged power bank for your phone — your most important tool for information and contact.
First aid and medications
Carry a compact first-aid kit and, critically, a few days of any prescription medications your family depends on. Add hygiene basics: hand sanitizer, wet wipes, a toothbrush.
Tools and documents
- A multi-tool or knife
- A hand-crank or battery emergency radio
- Duct tape and a few feet of cordage
- Cash in small bills
- Copies of IDs, insurance, and emergency contacts in a waterproof bag
Choosing and packing the bag
Use a comfortable backpack you can carry for a while — not so big that you are tempted to overload it. Weight is the enemy: a bag too heavy to carry is a bag that gets left behind. Pack the things you would need first (water, light, documents) where you can reach them, and keep the total manageable for the smallest person who might have to carry it.
One bag per person, plus a family plan
Each family member should have their own bag sized to their needs, including children and pets. Pair the bags with a simple family emergency plan: where you will meet, how you will communicate if separated, and your evacuation routes. Gear without a plan still leaves you guessing.
Maintain it
A go-bag is only good if it works when you grab it. Every six months, check expiration dates on food, water, and medications, swap seasonal clothing, test your flashlight and radio, and refresh the cash and documents. Store the bags somewhere you can reach instantly — by the door or in a closet near your exit, not buried in the attic.
Don’t forget the vehicle kit and get-home bag
Your bug-out bag lives at home, but emergencies do not wait for you to be there. Keep a smaller vehicle kit in your car — water, a blanket, a flashlight, jumper cables, a basic first-aid kit, and some non-perishable snacks — so a breakdown or sudden evacuation on the road does not catch you empty-handed. A get-home bag is the companion idea for people who commute: a compact pack with water, comfortable walking shoes, a charged power bank, and a snack, sized to get you from work back home on foot if you have to. Together with your home go-bag, these three layers cover wherever you happen to be when trouble starts.
Customize for your family and climate
The checklist is a starting point, not a finish line. Adjust it for the people and place you actually live in. Cold climates demand serious warmth — insulated layers, gloves, hats, hand warmers. Hot climates shift the priority to extra water, sun protection, and electrolytes. Families should pack comfort items for children — a small toy, a favorite snack — because a calm child is a safer child. Add copies of important documents, spare glasses, and anything your household genuinely cannot do without. The best bug-out bag is the one built around your real life.
Key takeaways

- Pack water, no-cook food, shelter, light, first aid, tools, and documents.
- Keep weight manageable and the bag where you can grab it instantly.
- Add a vehicle kit and a get-home bag for when you’re away from home.
Frequently asked questions
What is a bug-out bag? A pre-packed go-bag with three days of essentials so you can evacuate in minutes.
How heavy should it be? Light enough for the smallest person who might carry it — weight is the enemy.
Do I need one per person? Yes, sized to each family member, including children and pets.
Be ready to go — or to stay
A bug-out bag is the evacuation half of preparedness; staying put with stored supplies is the other half. Most events call for sheltering in place, but having a packed go-bag means the choice to leave is always available to you, instantly.

Practice with your bag. A go-bag you have never opened is a guess, not a plan. At least once a year, lay everything out, replace expired food, water, and medications, swap seasonal clothing, and actually lift the loaded pack to confirm each person can carry their own. Run a five-minute family drill: grab the bags, confirm your meeting point, and review your evacuation route. The goal is simple — on the worst day, leaving is automatic.
