Bug Out Bag Checklist: The Complete 72-Hour Emergency Kit Guide
Last updated: 2026-05-28
A bug out bag needs to work on the worst day of your life — when you have 10 minutes to leave your house and no idea when you're coming back. That's not the moment to discover your water filter is missing or your headlamp batteries are dead.
Here is the complete checklist, organized by category, with the items that matter most and the reasoning behind each call.
What a Bug Out Bag Actually Is (And Isn't)
A bug out bag — also called a 72-hour bag, get-home bag, or go bag — is a portable emergency kit built to sustain you for roughly three days if you need to evacuate quickly. Wildfire orders, flooding, extended power grid failure, chemical spills — any scenario where staying put is more dangerous than moving.
It is not a permanent off-grid living setup. It is not a year's worth of food storage. It is 72 hours of self-sufficiency in a pack you can carry out the door in under five minutes. That framing shapes every decision about what to include.
Water and Filtration
Water is non-negotiable. You can survive weeks without food. In a physically demanding, high-stress situation, three days without water will incapacitate you.
The math: one liter minimum per person per day under normal conditions — double that in heat or with heavy exertion. For 72 hours, that's 3–6 liters, far too heavy to carry entirely as stored water.
The practical solution: carry one 1-liter bottle plus a quality water filter. The LifeStraw Peak Series Personal Water Filter filters up to 4,000 liters and removes 99.999999% of bacteria and parasites. Back it up with Aquatabs purification tablets — filters can freeze or clog, tablets cannot. (For a full breakdown of filter types by use case, see our best camping water filters guide.)

Pack one stainless steel or aluminum bottle (usable over fire for boiling) and one collapsible reservoir for capacity when water sources are available.
Food
Target calories, not weight. Aim for 2,000–2,500 calories per day. Priorities:
- Calorie density: Trail mix, nut butter packets, and bars pack more calories per ounce than most food
- No-cook options: Assume you may not always be able to build a fire or use a stove
- Familiar foods: Three days of emergency rations is not the time to test unfamiliar foods under physiological stress
Strong choices: Clif Bars, RX Bars, individual nut butter packets, beef jerky, instant oatmeal (cold-soakable with enough water), hard candy for quick energy, instant coffee if you need it to function.
Shelter and Warmth
Exposure kills faster than hunger. Your shelter kit should cover ground insulation, overhead protection, and body heat retention.
- Emergency bivy: The SOL Escape Bivvy is waterproof, breathable, and weighs under 9 oz. It is not a comfortable night's sleep, but it keeps you alive
- Mylar emergency blankets: Pack two minimum — one to sleep under, one for signaling or additional wind protection
- Lightweight tarp: An 8×10 ft silnylon or Dyneema tarp at 10–14 oz covers more scenarios than a tent at a fraction of the weight
- Extra clothing: One moisture-wicking base layer, one insulating mid-layer, a packable rain poncho
- Wool socks: Two pairs minimum. Wool retains warmth when wet. Cotton does not.
Fire Starting
Three independent methods, minimum. If one fails, you have options.
- Primary: BIC lighter — the most reliable fire-start per ounce and per dollar on the market, period
- Secondary: Ferro rod and striker — functions when wet, thousands of uses, doesn't leak or lose fuel
- Tertiary: Waterproof matches in a sealed container
Include tinder you've prepared in advance: Vaseline-soaked cotton balls, fatwood sticks, or waxed cardboard in a waterproof bag. Finding dry natural tinder after 12 hours of rain is genuinely difficult even for experienced outdoorspeople.
First Aid
Build your kit around three scenarios: bleeding control, wound care, and personal medication management.
Minimum contents:
- Tourniquet (CAT or SOFTT-W — non-negotiable for trauma readiness)
- Israeli pressure bandage
- Nitrile gloves, 2 pairs
- Alcohol wipes and iodine swabs
- Steri-strips and butterfly closures
- Blister kit (moleskin, hydrocolloid pads)
- Ibuprofen and acetaminophen (different mechanisms — carry both)
- Diphenhydramine (Benadryl) for allergic reactions
- 30-day supply of any personal prescription medications, rotated every 6 months
- Compact first aid manual
Know what every item in your kit does before you need it.
Navigation
Your phone will die or lose signal. Never rely on it as your only navigation tool.
- Topographic map: Printed, of your region, in a waterproof bag or laminated
- Baseplate compass: Silva Ranger or Suunto A-10. Understand how to take a bearing
- Written rally point instructions: Where you're going, alternate routes, family meet-up locations — all written on paper that doesn't require a battery
Communication
- NOAA hand-crank/solar radio: Battery-free emergency alerts when cell networks are saturated or down
- Whistle: Fox 40 pealess whistle — 100+ decibels, no moving parts, works submerged
- Signaling mirror: Passive signaling that requires no battery and can be seen for miles in daylight
- USB power bank (20,000 mAh minimum): Phone communication for as long as power lasts; pre-charged and rotated quarterly
Documents and Financial
Pack in a sealed, waterproof bag:
- Color photocopies of: driver's license, passport, birth certificate, insurance cards, property deed or lease agreement, vehicle registration
- Cash: $300–$500 minimum, in mixed small bills. Debit and credit readers fail in power outages. Larger bills are harder to make change for in informal transactions
- Emergency contacts on paper — assume your phone is dead and you can't unlock it anyway
Tools and Illumination
- Multi-tool: The Leatherman Wave+ remains the benchmark — pliers, knife, saw, scissors, screwdrivers, wire cutters, file, and more in one tool at 8.5 oz
- Fixed-blade knife: A 4-inch fixed blade for tasks requiring more force than a folder allows — batoning wood, heavy cutting, defense
- Headlamp: Black Diamond Spot 400 or Petzl Actik Core, with two sets of lithium spare batteries (lithium outperforms alkaline in cold)
- Tactical flashlight: 500+ lumens, IPX4 water resistance minimum, for signaling and area illumination

How to Pack Your Bag
Pack by access priority. What you reach for first goes on top or in outer pockets.
- Outer pockets and top: First aid kit, headlamp, rain gear, snacks, water filter
- Middle section: Shelter gear, extra clothing, main food supply
- Bottom: Navigation tools, documents, heavier items
Target pack weight: no more than 20–25% of your body weight. A bag that slows you to a shuffle defeats itself. If your bag weighs 45 pounds and you're not in serious physical condition, you've built a weight problem, not an emergency kit.
Test it. Once a year, put it on and walk two miles. You will discover exactly what's missing, what's too heavy, and what you packed and forgot about.
Frequently Asked Questions
What should every bug out bag contain?
The non-negotiables: water (1L bottle plus filtration), 72 hours of calorie-dense food, emergency shelter (bivy or mylar blankets), fire starting kit (lighter, ferro rod, tinder), first aid kit with bleeding control capability, navigation tools (printed map and compass), headlamp with spare batteries, multi-tool, weather radio, USB power bank, important document copies, and cash. Add prescription medications. This covers all six core survival categories: water, shelter, fire, first aid, light, and communication.
What are the 7 essential survival items?
The seven items that matter most when everything else is stripped away: (1) water filtration — dehydration incapacitates before it kills, (2) fire starting — warmth, signaling, and water purification, (3) emergency shelter — hypothermia is survivable only with the right gear, (4) cutting tool — a fixed blade for shelter, food prep, and utility, (5) first aid supplies — especially bleeding control, (6) signaling device — a whistle or mirror to be found before you decide to move, (7) navigation — a compass and map when your phone is dead. Everything else in your kit is secondary to these seven.
What does a Doomsday prepper keep in their go bag?
The same core categories, but with greater redundancy and longer duration. Expect: 30+ day food supply rather than 72 hours, multiple water filtration methods, a HAM radio (Baofeng UV-5R is common) rather than just a weather radio, hard currency (gold or silver coins alongside paper cash), extended prescription medication supply, a more comprehensive trauma kit including hemostatic gauze and chest seals, a Faraday bag for electronics, and legally-held self-defense items. The core philosophy doesn't change — the difference is more of each essential, with greater redundancy, for longer timelines.
What are 20 items in an emergency kit?
FEMA's recommended baseline covers: (1) water — 1 gallon per person per day for 3 days minimum, (2) 3-day non-perishable food supply, (3) battery or hand-crank radio, (4) flashlight, (5) first aid kit, (6) extra batteries, (7) whistle, (8) dust mask, (9) plastic sheeting and duct tape for shelter-in-place, (10) moist towelettes and garbage bags, (11) wrench or pliers for shutting off utilities, (12) manual can opener, (13) local maps, (14) cell phone with charger and backup battery, (15) prescription medications and glasses, (16) copies of important documents in a waterproof container, (17) sleeping bag or warm blankets, (18) complete change of clothing per person, (19) cash in small bills, (20) household bleach and medicine dropper for water purification. This baseline covers immediate evacuation and shelter-in-place scenarios.
Build It Before You Need It
The biggest mistake in emergency preparedness is assuming you have more time than you do. A 72-hour bag built today, tested annually, and rotated every 6 months is worth more than a theoretically perfect kit that doesn't exist yet.
Start with the categories. Fill gaps over time. Rotate food and medications on a schedule. The goal is not a perfect bag — it's a ready one.
