Survival Gear Guide: Building Your First Emergency Kit
Most people don't own a survival kit until after the first time they needed one. A house fire, a 72-hour power outage, a car stuck in a snowstorm — any of these is enough to make the argument. This guide covers how to build a practical emergency kit and bug out bag from scratch, without overcomplicating it.
The Two Kits Everyone Should Have
Before you start buying gear, separate two different concepts:
- Home Emergency Kit: Stored at home. Covers 72 hours to 2 weeks of shelter-in-place scenarios — power outages, natural disasters, supply disruptions. Heavy is fine because you're not carrying it.
- Bug Out Bag (BOB): Grab-and-go. Covers 72 hours of evacuation. Should be light enough to carry at a jog, organized so you can find anything in the dark.
Build the home kit first. It's more likely to be used and less likely to have gear you don't need. Browse our survival gear collection to see what's worth having.
Bug Out Bag Essentials: The Core Categories
Every bug out bag is a compromise between weight and capability. Here's how to think through each category:
Water and Purification
72 hours at 1 liter per person per day means 3 liters minimum. That's heavy — 6.6 lbs. For a BOB, you carry less water and more purification capability. A squeeze filter handles any freshwater source. Purification tablets (iodine or chlorine dioxide) are a 1-ounce backup. A 1-liter collapsible bottle gives you flexibility.
Don't skip: You can go 3 days without water in mild conditions. In heat or exertion, that drops to hours.
Food
2,000 calories per day per person. For a 72-hour BOB, that's 6,000 calories. Calorie-dense, shelf-stable options: freeze-dried meals (add water), hard-tack biscuits, nut butter packets, jerky, chocolate. A lightweight camp stove is a significant morale boost on day 2, but it's optional for a true 72-hour kit.
Shelter and Warmth
An emergency bivy is non-negotiable. A quality tarp (8x10 ft silnylon) and 50 feet of paracord cover sleeping shelter. A mylar emergency blanket handles reflective warmth. Add a sleeping bag liner if weight allows. Check out camping gear for compact sleeping solutions.
Fire Starting
Three ignition sources: butane lighter, waterproof matches in a sealed container, ferro rod. Tinder that works wet: petroleum-jelly cotton balls in a small tin, commercial wax tinder tabs. Fire gives you warmth, water purification (boiling backup), signaling smoke, and psychological benefit. Don't minimize fire in your survival kit.
Navigation and Communication
Paper maps of your local region, a compass, and a battery bank + hand-crank emergency radio. A satellite communicator like a PLB or two-way satellite messenger is the single best investment for anyone spending time in remote areas. If you get hurt alone, 10 miles from a road, this is what gets you home.
First Aid
Your BOB first-aid kit needs to handle trauma, not just blisters. Minimum: pressure bandages, hemostatic gauze, tourniquet (CAT or SOFT-T), chest seals, nitrile gloves, irrigation syringe, SAM splint, and any personal medications (30+ day supply for prescriptions). Our emergency preparedness gear includes trauma-capable first-aid options.
Tools
A fixed-blade knife (4-5 inch blade, full tang) handles most field tasks. A multi-tool covers mechanical repairs. A small folding saw weighs under 4 oz and processes firewood far faster than a knife. 550 paracord (100 ft) has endless uses. Duct tape. Cable ties. A small headlamp with spare batteries.
How to Organize Your Bug Out Bag
Use a 40-50L pack with a hip belt and good back panel. Organize by access frequency and weight:
- Bottom: Sleeping gear, heavy items, rarely accessed
- Middle: Food, stove, tools
- Top / lid pocket: First aid, fire, headlamp, things you might need fast
- Hip belt pockets: Navigation, phone, snacks
Pack it once, then repack it in the dark. Everything should be findable by feel in a stressful scenario.
Home Emergency Kit: What's Different
Your home kit can be heavier and more comprehensive. Think in terms of what infrastructure you lose:
- No power: lanterns, headlamps, battery banks, hand-crank radio
- No running water: 1 gallon/person/day minimum (store 2 weeks' worth), gravity filter, bathtub liners for emergency collection
- No grocery stores: 2-week food supply per person, manual can opener
- No gas: camp stove with fuel canisters for cooking, heating
- No medical: comprehensive first-aid kit, 90-day medication supply, first-aid manual
The Most Common Mistakes in Building an Emergency Kit
Buying Without Testing
An emergency kit you've never used is a decoration. Run a 72-hour "grid down" exercise at home once a year. Cook with your stove, sleep in your bivy, filter your water. You'll find the gaps before you need them filled under pressure.
Over-Optimizing for Scenarios That Won't Happen
The most likely emergencies are boring: extended power outage, stuck in your car, minor medical emergency, short-term evacuation. Build for those first. Build for everything else after.
Ignoring Rotation
Check your kit every 6 months. Replace batteries, rotate food (eat it and replace), check medications for expiration. A kit with dead batteries is worse than no kit — it builds false confidence.
Start Small, Upgrade Continuously
The perfect emergency kit is the enemy of the good one. Start with water, fire, light, and shelter. Add a layer of capability every month. In six months, you'll have a legitimate prepping setup that would handle most realistic emergency scenarios — and you'll understand why each item is there.
