Everything you need to build a reliable 3-day emergency kit - what to pack, how to prioritize, and how to make sure it's actually ready when you need it.
What is a 3-Day Bag?
A 3-Day Bag - also called a go-bag, 72-hour kit, or bug-out bag - is a portable kit that contains everything you need to survive for at least 72 hours if you are forced to leave your home.
Every member of your family should have one. The goal is simple: stay self-sufficient long enough to reach safety.
Start Simple - Don't Overthink It
The biggest mistake people make is waiting until they can afford "perfect" gear.
Don't. Start with a basic, complete kit as soon as possible. You can always upgrade later. Done is better than perfect.
How to Build Your Bag
Your pack should be around 55 liters for adults (smaller for kids) and weigh 15-20% of your body weight. Comfort matters - make sure it has a waist strap for proper load support.
Core Categories of Gear
Think in terms of survival needs: water, food, shelter, warmth, light, and tools.
Food (3 Days)
Pack lightweight, high-calorie, non-perishable items. You're not eating for comfort - you're eating for energy.
- Backpacking meals
- MREs
- Lifeboat rations
Water
Water runs out fast. Plan for resupply.
- Start with at least 2 liters per person
- Include a way to collect, filter, and store water
Cooking / Boiling Water
Hot water means safe water and hot meals.
- Small camp stove + fuel
- Metal cup or an integrated system like a Jetboil
Clothing
Adjust based on your local climate.
- Insulating layer (wool or fleece)
- Lightweight rain shell
- 2 extra pairs of socks and underwear (store in a waterproof bag)
- Scarf or shemagh
Light - Have 3 Sources
- Headlamp
- Handheld flashlight
- Area light
Bring spare batteries or rechargeable options. Emergency candles can also provide light, heat, and fire-starting capability.
Fire Kit
Always have redundant ways to start a fire.
- Bic lighter
- Ferro rod
- Tinder (fatwood, fire rope, etc.)
Shelter
This gives you the ability to stay dry and protected if you're outdoors overnight.
- Simple tarp
- Ridgeline cord
- Stakes
Cutting Tools
Each serves a different purpose - redundancy matters.
- Fixed blade knife
- Folding pocket knife
- Multi-tool
First Aid Kit
Basic medical supplies for common injuries. This is not optional.
Documents & Cash
- Copies of IDs and important documents
- Emergency contacts
- $200 cash in small bills
- Waterproof notepad and pencil
Special Considerations
Depending on your family's needs, also include:
- Feminine hygiene products
- Infant formula and diapers
- Prescription medications
- Glasses or contacts
Conclusion
Your 3-Day Bag is not about comfort - it's about mobility and survival.
- Keep it simple
- Keep it ready
- Keep it accessible
You can refine and upgrade your gear over time, but the most important step is this: build your bag now - not later.
