Field briefing
A 72-hour kit sounds like a gear problem until you do the water math. One person needs roughly three gallons for three days before you count pets, hot weather, cooking, hygiene, or anyone with medical needs. This guide turns the vague advice into a simple household target.
Printable checklist
Start with the boring baseline
Use one gallon per person per day as the easy planning number. For a solo apartment, that means three gallons. For two adults and a dog, the target jumps quickly.
The best kit is not the one with the coolest pouch. It is the one where everyone can actually drink water on day three.
Add real-life modifiers
Hot weather, infants, pets, medical needs, shelf-stable meals, and basic hygiene all increase your water needs. If your food plan includes dehydrated meals, remember that those meals consume water too.
If storage is tight, build in layers: a few gallons ready now, extra collapsible containers, and a filter or tablets for backup sources.
