Bug Out Bags & Go Bags: The Complete Guide Hub

By Wilderness First Responder · Former USFS Wildland Firefighter · FEMA CERT Trainer Updated

A bug out bag (BOB) is a pre-packed bag you grab when you have to leave home in a hurry: whether that's a wildfire evacuation, a flood, a power grid failure, or any situation where staying put is no longer safe. The right bag, packed with the right gear, can mean the difference between managing an emergency and being overwhelmed by one.

This hub covers everything from choosing your first bag to specialist kits for families, women, kids, seniors, and pets. Use the guides below to build, buy, or audit your bug out bag.

Why a Bug Out Bag Matters

The 72-Hour Baseline

FEMA and Ready.gov both recommend every household keep enough supplies to be self-sufficient for at least 72 hours, since that's a realistic window before outside assistance reliably arrives after a major disaster. A bug out bag is that 72-hour supply made portable: packed in advance, ready to grab, rather than something you try to assemble while an evacuation order is already in effect. The actual contents matter less than having made the decisions (what to pack, where it lives, who's responsible for grabbing it) before you're under pressure.

Packed Weight Is the Detail Most People Get Wrong

A bag stuffed with everything that seems useful is often the bag that gets left behind, because it's too heavy to actually carry for any distance. A loaded bug out bag should generally stay within 20-30% of the carrier's body weight; for a 150 lb adult, that's roughly 30-45 lbs. Building toward a target weight, not just a feature checklist, is what makes a bag something you'd actually grab and carry rather than something that sits in a closet unused.

One Bag Rarely Fits the Whole Household

A single all-purpose bag built around an able-bodied adult doesn't automatically work for a toddler, an elderly parent, or a pet, and treating "the bug out bag" as one object for the whole family is a common planning gap. Distribute shared, heavy items (water filtration, a larger first aid kit, cooking gear) across whichever adults are carrying the most capacity, and build lighter, person-specific bags for kids, seniors, and anyone with a disability around what they can actually carry or what caregivers need to carry for them.

Start Here: Essentials

Begin with a real bag (not a cheap tactical-looking shell), a checklist so nothing critical gets missed, and an understanding of what "72 hours" actually requires in practice.

By Person

A single generic bag rarely fits every household member; kids, seniors, pets, and anyone with a disability each have real differences in what actually needs to be packed.

Specialist Bags

Beyond the classic 72-hour bug out bag, several related bag concepts solve more specific problems: getting home when your commute is disrupted, staying put instead of leaving, or carrying gear daily rather than just in an emergency.

Bug Out Bags FAQ

How much should a bug out bag weigh?

Generally no more than 20-30% of the carrier's body weight. For a 150 lb adult, that's roughly 30-45 lbs fully loaded. Weigh your packed bag and adjust before an emergency, not during one.

Should I buy a pre-packed bug out bag or build my own?

Building your own is usually the better outcome: pre-packed kits frequently include lower-quality supplies to hit a price point. Buy a quality bag separately (see our best bug out bags guide) and pack it with gear you've actually chosen.

How many bug out bags does a family need?

One per adult and older child at minimum, sized to what that person can realistically carry. See our go bags for families guide for how to distribute shared items like water filtration and first aid across multiple bags.

What's the difference between a bug out bag and a get home bag?

A bug out bag is built for a full evacuation, typically 72 hours of self-sufficiency. A get home bag is a smaller, lighter kit kept at work or in a vehicle, built specifically to get you from where you are back to home if your normal commute is disrupted, not to sustain you for days.
