When disaster strikes, you have minutes — not hours — to grab what you need and go. Whether it's a wildfire, hurricane, or unexpected evacuation order, the difference between chaos and calm often comes down to one thing: preparation.

A 72-hour kit (also called a bug-out bag or go-bag) contains everything you need to survive for three days without outside help. Why 72 hours? That's typically how long it takes for emergency services to establish relief operations after a major disaster.

Here's how to build one that actually works.

The Foundation: Water and Food

Water is your most critical supply. The human body can survive weeks without food but only days without water.

In NomadCore: PackMind tracks your water supply with expiration dates and quantities. Set it once and get reminded when it's time to rotate — no more guessing when you last swapped out those jugs.

Food should be non-perishable, calorie-dense, and require no cooking.

Don't forget a manual can opener. It's a small item that becomes critical when you're staring at a can of beans with no way to open it.

First Aid: Beyond the Basics

A basic first aid kit is essential, but most pre-made kits are designed for minor cuts, not emergencies. Upgrade yours with:

Standard Items

Emergency Additions

A first aid kit is only as good as your knowledge. Take a basic first aid course — many are free through the Red Cross.

In NomadCore: Log every first aid item in PackMind with expiration dates. The app also includes offline first aid reference guides — step-by-step procedures you can pull up without cell service.

Light, Power, and Communication

When the grid goes down, you need alternatives.

Lighting

Power

Communication

The hand-crank radio is non-negotiable. When cell towers are down and the internet is out, NOAA weather radio may be your only source of official information.

In NomadCore: Store ICE contacts for one-tap dialing, download offline maps of your area, and keep your family communication plan accessible without internet. Your phone becomes a self-contained emergency hub.

Shelter and Warmth

You can't always count on finding shelter. Pack items that let you create your own.

Clothing to Include

Hypothermia can occur in temperatures as high as 50 degrees F if you're wet and exposed. Don't underestimate shelter.

Documents and Cash

In an evacuation, you may need to prove who you are without access to the internet.

Keep Copies Of

Store These

Cash: Keep $200-500 in small bills. ATMs don't work without power, and card readers fail during outages.

In NomadCore: Store digital copies of critical documents in your emergency plan. Every family member with the app gets access — even offline. No USB drive to lose, no paper to get wet.

Tools and Miscellaneous

The items that don't fit a category but prove invaluable:

Sanitation

Special Considerations

For Families with Children

For Pet Owners

For Those with Medical Needs

Choosing the Right Bag

Your container matters. A 72-hour kit needs to be:

A quality hiking backpack (40-60 liters) works well for most people. Avoid suitcases — wheels don't work on debris-covered roads.

Weight guideline: Your packed kit should be no more than 20% of your body weight if you expect to move quickly.

Storage and Maintenance

A kit you can't find or that's expired is useless.

Storage

Maintenance Schedule

In NomadCore: PackMind automates your maintenance schedule. Track every item's expiration date, get notifications before things go bad, and do inventory checks right from your phone. No spreadsheet required.

Start Today, Not Tomorrow

The best time to build a 72-hour kit was yesterday. The second-best time is now.

You don't need to buy everything at once. Start with water and first aid. Add food next week. Build your kit over a month, and you'll have peace of mind that lasts for years.

Disasters don't announce themselves. But when the alert hits your phone at 3 AM, you'll be ready.

Track your emergency supplies, manage expiration dates, and build comprehensive emergency plans with NomadCore — the offline-first survival app that keeps you prepared when it matters most.
