The term "go-bag" has accumulated a lot of mythology. Online communities post photos of bags with $3,000 worth of gear. Survival forums debate whether you need a fire steel or a lighter. Almost none of this is useful to a family with two kids, 15 minutes to leave, and a SUV that's already full.
The actual goal is simple: 72 hours of self-sufficiency without going back home or stopping at a store. That's it. Everything else is a nice-to-have.
Weight First, Everything Else Second
Before you buy a single item, establish your weight limit. The standard is 25% of the carrier's body weight. For a 150-pound adult, that's 37 pounds maximum — and that's the ceiling, not the target. Realistically, a well-packed go-bag for one adult runs 20–25 pounds.
Water is the main culprit. One gallon of water weighs 8.3 pounds. Three days of water for one person at the FEMA minimum is 24.9 pounds — more than the entire target bag weight. This is why you carry 1–2 days of water and a filter, not 3 days of water.
A bag that's too heavy to walk a mile will stay in the car. A bag you can carry for two hours is a go-bag. Weigh your bag before you consider it done.
For families with children: kids over 8 can carry their own small pack. Keep it to 10–15% of their body weight. Water, snacks, a laminated contacts card, and one comfort item. The comfort item matters — in a stressful evacuation, a familiar object does more for a child's ability to function than most adults expect.
Tier 1: The Non-Negotiables
These are the items to prioritize before anything else. If your bag only has these, it's still functional. Build the foundation before adding anything else.
-
Tier 1 Water — 1 liter per person minimum Plus a LifeStraw or Sawyer Mini filter. This combination lets you refill from any source.
-
Tier 1 Document copies — in a waterproof bag IDs, passports, insurance cards, medical records. What you can prove determines your options in the first 72 hours.
-
Tier 1 First aid kit — plus a printed first aid manual The manual works when your phone doesn't. Open the kit once so you know what's in it.
-
Tier 1 Food — 2,000+ calories per person per day Caloric-dense, no-cook options. Clif bars, trail mix, peanut butter, jerky. Not MREs unless you've used them before.
-
Tier 1 Headlamp — with spare batteries Not a flashlight. Hands-free is the difference between functional and hobbled in low-light conditions.
-
Tier 1 Phone charger — 20,000 mAh portable battery Enough for 3–4 days of moderate phone use. Check the charge every time you refresh the bag.
-
Tier 1 Broken-in walking shoes or boots New shoes give you blisters by mile two. Pack shoes you've already walked in for hours. Waterproof preferred.
-
Tier 1 Laminated local map — plus evacuation routes GPS fails when power grids fail. A printed, laminated map never needs batteries.
Tier 2: Once the Foundation Is Covered
Add these once every Tier 1 item is packed and the bag weight is confirmed. Do not skip Tier 1 items to fit Tier 2 items.
-
Tier 2 Mylar emergency blankets — one per person Also works as ground insulation, signaling mirror, and emergency shelter material.
-
Tier 2 Multi-tool — Leatherman or equivalent Keep it accessible, not buried at the bottom.
-
Tier 2 Whistle — pealess design Louder than shouting and works when your voice fails. Works in cold and wet.
-
Tier 2 Hand-crank NOAA radio Emergency broadcasts without power or charged batteries. Often the only way to know what's happening during an extended outage.
-
Tier 2 50–100 feet of paracord Shelter rigging, clothesline, lashing, repairs, improvised carry straps. Weighs almost nothing.
-
Tier 2 Collapsible water container Lets you refill as you move. Pair with the filter. Combination weighs under half a pound.
-
Tier 2 Work gloves — one pair per adult Debris work after a structural event is where hands get damaged first. Also doubles as cold-weather protection.
-
Tier 2 Electrolyte packets — a dozen per person Dehydration affects decision-making before it registers as thirst. Takes up less space than a granola bar.
What to Leave Out
Most go-bag guides add items indefinitely. The real discipline is subtraction.
Skip heavy redundancies. A full-size camp stove and three liters of water both address the same problem. Pick one strategy and commit to it. The filter plus collapsible container weighs a fraction of three liters of stored water and solves the same problem better.
Packing items you've never used before. A tourniquet in a kit is only useful if you've trained with it. An unfamiliar item under stress becomes a liability. Only pack tools you know how to use.
Skip bulky extras in Tier 1. Solar panels, full rain gear sets, tactical vests, water bladder systems — all of these have their place in a specific context. A family getting to a relative's house 60 miles away doesn't need a tactical vest.
Cotton clothing. Cotton holds moisture against your skin. In cold and wet conditions, that's how hypothermia starts. Every wearable layer that matters should be synthetic or wool. This is not a minor detail.
Choosing the Right Bag
The bag itself is less important than most people think. A standard 30–40L hiking daypack works. It should have:
A padded hip belt that transfers weight off your shoulders. Multiple external access pockets so you're not unpacking the whole bag for a first aid kit. Durable zippers — MOLLE attachment points are optional and often unnecessary for civilian use.
Do not buy a military-style bag in a tactical color. Beyond the practical reasons — tactical bags are heavy before you add anything — it draws attention in situations where you don't want attention.
Maintenance: The Part Everyone Skips
A go-bag expires. Food expires. Medications expire. Battery power drains. Document copies go out of date when addresses change. A bag you packed three years ago and never opened again is not a go-bag.
The maintenance is simple: refresh the bag twice a year, on January 1 and July 1. On each refresh:
Rotate food and water. Check medication expiration dates. Update document copies if anything has changed. Test all batteries. Confirm the bag still fits whoever is carrying it (this matters for children especially).
Set both calendar reminders now. Two events and the bag stays current indefinitely.
Once the bag is packed, put it on and walk a mile. If it's too heavy to do that, it won't get carried when it actually matters. Adjust until you can walk the mile.
