PREPPING FUNDAMENTALS

How to Build a Get-Home Bag for SHTF

The bag that lives in your vehicle and gets you home on foot when roads lock up and your phone dies.

Most preppers build a 72-hour bug-out bag for leaving home. Fewer build the bag that gets you home in the first place. Think about where you are when SHTF: at work, at the gym, on the highway. The grid goes down. Cell towers fail. Traffic locks up within the hour. You are 20, 30, 40 miles from home. You have what’s in your car. A get-home bag is purpose-built for a single mission: get from wherever you are back to your family, on foot if necessary, in 24 to 48 hours. It is not a bug-out bag. It is lighter, faster, and mission-specific.

The Core Mission: 24–48 Hours on Foot

Size your get-home bag for a 24–48 hour foot movement covering up to 30 miles. That covers most commuter distances. The bag should weigh no more than 20–25 lbs fully loaded — you may be moving through urban and suburban terrain, possibly in work clothes. Weight is the enemy. Every item earns its place with a specific job. Think prepper priority order: water first, then food, then navigation, then comms, then medical, then security.

Water: The First Problem

Carry two 32oz water bottles full. Add a Sawyer Squeeze water filter or LifeStraw personal filter — these weigh almost nothing and turn any stream, puddle, or tap into safe drinking water. Understanding water filtration options is important here: for a get-home bag, the straw-style filter is the right tool. You’re moving, not camping.

Food: Calorie-Dense and No-Cook

For 24–48 hours, you need approximately 3,000–4,000 calories of high-energy food that requires no preparation. Pack: high-calorie energy bars (400+ calories each), jerky and hard salami for protein and salt, and peanut butter packets. No cooking gear needed. Eat while moving. This is not a comfortable meal scenario — it’s fuel for the mission.

Navigation: Maps Before Phones

Cell towers fail. GPS apps require data. Your navigation solution cannot depend on either. Pack printed topographic and road maps of your home region — every county between your workplace and your home, plus a 20-mile buffer in every direction. Add a baseplate compass and know how to use it. Do a dry run on foot before Day-X: walk your primary and alternate routes, identify your water sources, note which bridges flood.

Communications: Know the Situation

A GMRS handheld radio lets you communicate with your family while moving and monitor local traffic. A solar hand-crank emergency radio lets you receive broadcasts without burning battery. Keep both charged and stored in a small Faraday bag — an EMP is the most likely cause of a simultaneous, wide-area grid collapse. Your full comms plan lives at home, but these two items handle the get-home mission.

Medical: Field-Grade Trauma Kit

Your get-home bag needs a compact IFAK (Individual First Aid Kit) with a CAT tourniquet, Israeli bandage, chest seals, and gloves. Blisters and muscle injuries are more likely than gunshot wounds, so also add moleskin blister pads and ibuprofen and electrolyte packets. See the full trauma kit guide and best pre-built trauma kit options for the full build list.

Tools and Light

A quality folding knife or multi-tool handles most tool needs. A headlamp with extra batteries keeps your hands free for navigation at night. Duct tape and paracord handle field repairs. A lightweight emergency bivvy and poncho handle an unplanned overnight. Keep it all in a low-profile grey or olive daypack that doesn’t scream “I have supplies.”

Keep One Bag Per Vehicle, Always Staged

The get-home bag lives in your car. Not your garage. Not your closet. Your car. Rotate perishables (food and batteries) annually. Check water containers every 6 months. Keep a change of weather-appropriate clothes in the bag — getting home in January in dress shoes is its own emergency. Your bug-out vehicle may get you most of the way home — the bag handles the last leg on foot when roads lock up completely.
