The bug-out bag is perhaps the most mythologised piece of emergency equipment in the prepping world. Online forums are full of elaborate kits costing thousands of pounds, packed with tactical gear and survival tools most people will never use.
This guide strips it back to reality. What does a functional bug-out bag actually need? What do most lists include that you do not need? And how do you build one that works for your actual life?
What a Bug-Out Bag Actually Is
A bug-out bag — also called a go-bag or 72-hour kit — is a pre-packed bag containing everything you need to function for 72 hours away from home. You would use it if your home becomes uninhabitable (fire, flood, structural damage), you receive an evacuation order, or staying becomes more dangerous than leaving.
It is not a survival kit for living indefinitely in the wilderness. It is a practical bag that means you can leave home in five minutes and function reasonably well for three days.
The Weight Rule
Your bug-out bag should not exceed 25% of your body weight. For most adults, this means under 20-25 lbs. A bag you cannot comfortably carry for an hour is not a functional bug-out bag.
The Essential Items (Non-Negotiable)
Water (Critical):
- 2 x 1-litre water bottles, filled
- Water purification tablets
- Filter straw (LifeStraw or Sawyer Mini)
Food (Critical):
- 6 x protein bars or similar (high calorie density, no preparation needed)
- Peanut butter single-serve packets
- Hard candy or trail mix
Design your 72-hour food supply to require zero cooking and zero utensils if possible.
First Aid (Critical):
- 10 x assorted bandages
- Sterile gauze pads and conforming bandage roll
- Antiseptic cream
- Personal prescription medications (3-day supply minimum)
- Household medical reference card
- Nitrile gloves
Light and Power (Critical):
- Headlamp with fresh batteries
- Fully charged power bank (20,000 mAh+)
- USB charging cable for your phone
Documents and Finance (Critical):
- $100-150 cash in small denominations
- Photocopied critical documents in waterproof bag
- Written emergency contact list and meeting points
- Physical paper map
Warmth (High Priority):
- 2 x emergency mylar blankets
- Rain poncho
- Change of clothes (2 pairs socks and underwear, one warm layer)
Tools (High Priority):
- Multi-tool (Leatherman or equivalent)
- Small roll of duct tape
- Lighter and waterproof matches
- Notepad and pen
What Most Bug-Out Bag Lists Include That You Do Not Need
- Full-size tent: For a 72-hour evacuation, you are almost certainly going to a friend’s house, a hotel, or an emergency shelter. Adds 3-6 lbs of weight you will almost certainly never use.
- Elaborate cooking systems: Stove, fuel canister, pot, utensils. For 72 hours, just eat your food cold. Saves 2-4 lbs.
- Full survival tools: Hatchet, saw, snare wire, fishing kit. Unless you live in a genuinely remote area, near-zero realistic utility.
- Redundant items: Four fire-starting methods, three types of purification. Pick the best option and leave the rest.
- Expensive tactical gear: A $200 tactical backpack provides no benefit over a $30 daypack for 72-hour use.
Choosing the Right Bag
Requirements: 30-40 litre capacity, multiple compartments and pockets, comfortable shoulder straps, reasonably weather-resistant. A quality daypack from a discount sports store ($25-35) is entirely adequate.
Organisation Inside the Bag
- Quick-access exterior pockets: Headlamp, phone cables, cash, emergency contact card
- Top of main compartment: First aid kit, power bank, documents
- Middle of main compartment: Food, water bottles
- Bottom of main compartment: Clothing, blankets, rain poncho
- Side pockets: Water purification, multi-tool, notepad
The Audit System
Set a 6-month reminder to audit your bag. Check: battery level on power bank, expiry dates on food and medications, cash amount, condition of all items. A bug-out bag that has not been checked in a year may fail you when you most need it.
