Why This Isn’t a Pre-Made Kit
Most store-bought “72-hour kits” look complete but cut corners on the things that matter. This page is modular so you can choose reliable pieces, avoid filler, and build a kit that actually performs. Buy it all at once or build it over time.

FAQ
Quick answers to the most common 72-hour bug-out bag questions.
What is a 72-hour bag supposed to do?
A 72-hour bag is built to keep you functional for three days during a disruption: safe drinking water, basic warmth, light, first aid, and the ability to move and solve problems without relying on stores or power.
Do I need to buy a pre-made kit?
No. Most pre-made kits look complete but underdeliver on core functions (water, light, power, and real first aid). Building modular lets you choose reliable pieces and upgrade over time.
How much should a 72-hour bag weigh?
There’s no single number because fitness and terrain matter. A good rule is: keep it light enough that you can carry it for an hour without needing a break. If it’s too heavy, you’ll abandon it or strip it down when it matters.
What matters more: food or water?
Water. Food helps energy and morale, but hydration and safe drinking water come first. Build water capacity + purification, then add simple, reliable calories.
Is a flashlight enough, or do I need a headlamp?
A headlamp covers hands-free work (moving, medical, repairs). A small flashlight can be your backup. The goal is reliable light with redundancy — not “max lumens.”
Should I rely on solar charging in an emergency?
Solar can help, but don’t treat it as your only plan. Weather, shade, and time make solar unreliable. Have a primary power bank and at least one backup method (spare batteries, hand-crank radio, or vehicle charging if applicable).
What’s the biggest mistake people make building a 72-hour bag?
Buying random items instead of covering functions. If your water plan fails, light fails, or first aid is weak, the “extra gear” doesn’t matter. Build function-first, then fill in comfort items that keep you functional.
How often should I check or refresh my bag?
Quick check every 3–6 months: batteries charged, food within date, meds current, and seasonal clothing updated. The best bag is the one that still works when you grab it.
