Section 02 — Choosing the Bag

Right Size, Right Type

Balance capacity against portability. A 30-liter backpack typically holds 72 hours of supplies for one person while keeping your hands free to navigate hazards or assist others. Waterproof exterior, padded straps, and a ventilated back matter as much as liters.

Feature Small Daypack 40L Hiking Backpack ★ Compact Duffel
Capacity 10–15 liters 30–40 liters 20–30 liters
Portability ✓ High, easy to carry ~ Moderate, more weight ✓ High, flexible carry
Organization ✗ Limited compartments ✓ Multiple compartments ~ Simple, open space
72-hr fit ✗ Too small for full kit ✓ Ideal for one adult ~ Tight, hard to carry far
Section 03 — Priority Chain

Top 5 Essentials You Can’t Skip

Pack in this order. Even if your bag isn’t perfect, these five keep you safe, connected, and warm no matter what happens.

1

Water

One liter per person per day minimum. Collapsible containers save space; dehydration impairs judgment fast.

2

Medications

Prescriptions, backup supplies, and copies. Without them, chronic conditions can complicate evacuation.

3

Communication

Power bank, battery radio, whistle. Your link to rescue when networks and power fail.

4

Documents

ID, insurance, medical info, photos—in a waterproof pouch. Streamlines rescue and recovery.

5

Warmth

Thermal blanket, poncho, sturdy shoes. Prevents hypothermia in sudden weather changes.

Section 04 — Weight Reality Check

Water Is Heavy: Why You Can’t Carry It All

Water weighs about one kilogram per liter, so an evacuation bag cannot hold a complete multi-day supply. Carry a modest amount and plan to source the rest at home, in your vehicle, or at your destination via tablets or filters.

Carried in go bag (1 day)1 kg / 1 L
Recommended 72-hr total need3 kg / 3 L
Family of four, 72 hrs12 kg / 12 L
Section 05 — Maintenance Cycle

Keep It Ready, Every Six Months

A stale kit is a false sense of security. Review your bag twice a year and after every use—replace expired items, update documents, rotate batteries, check clothing sizes, and test every piece of equipment.

Rotate

Swap expired medications, food, and batteries. Verify water containers are sealed and intact.

Update

Refresh documents, contacts, prescriptions, and photos. Adjust for growing kids and changing needs.

Test

Check flashlights, radios, and power banks. Make sure everyone can use every tool under stress.

Practice

Run a 15-minute quick-departure drill. Everyone should know where the bag lives and how it’s organized.

Section 06 — FAQ

Frequently Asked Questions

How big should a go bag be?

Small enough to carry comfortably—around 30 liters is ideal for most adults, balancing capacity with portability so you can evacuate quickly without feeling weighed down.

How many days should it cover?

Most experts recommend at least 72 hours—three days—of supplies. That gives you time to reach help while authorities respond and assistance arrives.

Does every family member need a bag?

Yes. Individual bags prevent overloading one person. Dependents’ supplies can be distributed among adults, but each person should carry a manageable kit.

How much water should I pack?

About one liter per person per day. Since water is heavy, carry a manageable amount and plan to source more via treatment tablets or filters.

Where should I store the bag?

Near your main exit, in a dry, accessible spot protected from extreme temperatures and pests—reachable even if the power goes out.

What about pets and special needs?

Customize every bag for children, older adults, disabilities, medical devices, allergies, and pets—including vaccination records and compact pet food.

Know Exactly What to Pack in Your Emergency Bag

The first step in building your grab-and-go kit is understanding what essentials truly matter. Think of your bag as a compact support system, not a mini home. You need enough supplies to keep you safe and comfortable for at least 72 hours, but not so much that it becomes a burden to carry.

For example, if you live in a wildfire-prone area, your priorities might shift toward respiratory protection and eye masks. If floods are common, waterproof clothing and sturdy boots take precedence. The key is to tailor your kit to your local risks and personal needs, including medical conditions, age, and climate.

Here’s a core packing list to get you started:

Understanding why each item matters helps you make informed choices. For instance, carrying extra batteries ensures your communication devices stay powered when you need them most, but adding too many can increase weight unnecessarily. Prioritizing multi-use items—like a thermal blanket that insulates, reflects heat, and can double as a ground cover—maximizes utility while minimizing bulk. Knowing the tradeoffs between weight, size, and functionality allows you to customize your kit effectively, ensuring you’re prepared without overburdening yourself.

How to Choose the Right Size and Type of Bag

Picking the right bag is about balancing capacity and portability. A bag that’s too small won’t fit everything you need and could leave you unprepared, while one that’s too large might be too heavy or cumbersome to carry quickly. The goal is a lightweight, durable backpack that distributes weight evenly and leaves your hands free to navigate hazards or assist others.

For instance, a high-quality 30-liter backpack typically holds enough supplies for one person for 72 hours without becoming a burden. But beyond capacity, consider the implications of material and design. A waterproof exterior protects your supplies from rain or flooding, which is crucial in many emergency scenarios. Padded straps and a ventilated back help prevent fatigue during prolonged carrying, which can be a critical factor if you need to travel long distances or hike through difficult terrain.

Compare options:

Feature Small Daypack 40L Hiking Backpack Compact Duffel
Capacity 10-15 liters 30-40 liters 20-30 liters
Portability High, easy to carry Moderate, more weight High, flexible carry
Organization Limited compartments Multiple compartments Simple, open space

Remember: comfort and ease of access matter more than capacity. Testing your bag by packing it with actual supplies and walking around helps you gauge whether it’s manageable and fits your physical capabilities. A well-chosen bag minimizes the risk of injury, fatigue, or delay during an actual emergency, and understanding the implications of your choice helps you balance preparedness with practicality.

What to Pack First: Top 5 Essentials You Can’t Skip

In a rush, certain items are absolute must-haves. These are the core essentials that keep you safe, connected, and warm, no matter what happens. Prioritizing these items ensures that even if your bag isn’t perfectly packed, you have the critical tools to survive and seek help.

Here are the top five:

  • Water: About one liter per person per day at minimum. Consider compact bottles or collapsible containers. Water is vital for hydration, and dehydration can impair your decision-making and physical ability in an emergency.
  • Medications: Prescriptions, backup supplies, and copies of prescriptions. They are your lifeline, especially for managing chronic conditions. Without medication, your health could deteriorate rapidly, complicating evacuation efforts.
  • Communication tools: Fully charged power bank, a battery-powered radio, and a whistle to attract attention. These tools are your links to the outside world and can be lifesavers if you need rescue or assistance.
  • Important documents: ID, insurance, medical info, and recent photos, stored in a waterproof pouch. Having quick access to these can streamline rescue or recovery efforts and prevent identity or legal issues.
  • Warm clothing and shelter: A thermal blanket, rain poncho, and sturdy shoes, ready for sudden weather changes. Proper clothing helps prevent hypothermia, and shelter items keep you protected from the elements, which is crucial in unpredictable conditions.

For example, during a wildfire evacuation, prioritizing water and masks over bulky items ensures you can breathe safely and stay hydrated. Recognizing why each item matters and understanding the potential tradeoffs—such as weight versus necessity—allows you to craft a kit that’s both comprehensive and manageable. This strategic selection supports your safety and resilience, especially in high-stress situations where every second counts.
