What Is a Bug-Out Bag?

A bug-out bag (BOB) — also called a go-bag or 72-hour kit — is a pre-packed bag you can grab at a moment's notice when you need to evacuate quickly. The goal is simple: sustain you and your family for at least 72 hours without access to stores, utilities, or emergency services.

The challenge is building one that's comprehensive enough to cover your needs but light enough to actually carry. Here's a practical, category-by-category breakdown.

Water and Hydration

Water is your highest priority. Without it, survival time is measured in days.

  • Water storage — at least 1 liter per person per day; collapsible bottles save space
  • Water purification tablets — iodine or chlorine dioxide for treating natural water sources
  • Portable water filter — a hollow-fiber filter straw or squeeze-style filter
  • Metal water bottle or pot — doubles as a boiling vessel

Food and Nutrition

Focus on calorie-dense, non-perishable foods that require minimal preparation:

  • Energy bars or meal replacement bars
  • Freeze-dried or dehydrated meals (just add water)
  • Nuts, jerky, and dried fruit
  • Peanut butter packets
  • A compact camp stove and fuel canisters (optional but highly useful)

Aim for roughly 1,500–2,000 calories per person per day. Don't forget a manual can opener if packing any canned goods.

First Aid

A comprehensive first aid kit is non-negotiable. Key items include:

  • Adhesive bandages in multiple sizes
  • Sterile gauze pads and medical tape
  • Elastic bandage wrap
  • Antiseptic wipes and antibiotic ointment
  • Tweezers, scissors, and a scalpel or razor blade
  • Pain relievers, antihistamines, and anti-diarrheal medication
  • Any personal prescription medications (minimum 7-day supply)
  • CPR face shield

Shelter and Warmth

  • Emergency mylar blankets — lightweight, compact, and highly effective
  • Compact rain poncho or waterproof jacket
  • A lightweight tarp or emergency bivy for shelter
  • Extra socks, underwear, and a warm base layer
  • Work gloves

Navigation and Communication

  • Physical maps of your local area and evacuation region (don't rely on a phone battery)
  • A quality compass
  • Battery-powered or hand-crank emergency radio (NOAA weather alerts)
  • Fully charged power bank for your phone
  • Whistle for signaling rescuers

Tools and Fire Starting

  • Multi-tool or Swiss army knife
  • Fixed-blade knife
  • Waterproof matches, a lighter, and a ferro rod (at least two fire-starting methods)
  • Headlamp with extra batteries
  • Duct tape and 550 paracord (30+ feet)
  • Folding shovel (optional, but useful)

Documents and Money

  • Waterproof pouch with copies of: ID, passport, insurance cards, medical records, bank account info
  • Cash in small bills — ATMs and card readers may be offline
  • A USB drive with digital copies of critical documents

Hygiene and Sanitation

  • Hand sanitizer and biodegradable soap
  • Toilet paper and waste bags
  • Toothbrush and toothpaste
  • Feminine hygiene products as needed
  • N95 masks (useful for wildfire smoke, dust, and airborne hazards)

Choosing the Right Bag

The bag itself matters. Look for a 40–60 liter backpack with padded shoulder straps, a hip belt, and a rigid frame. Molle webbing allows you to attach additional pouches. Keep the total loaded weight under 25% of your body weight for comfortable movement over distance.

Maintain and Rotate

Check your bag every 6 months. Rotate food and water, replace expired medications, and update documents. A bug-out bag you haven't checked in two years is not a reliable bug-out bag.
