A 72-hour emergency kit can turn a bad situation into a manageable one. Most families know they need one, but the questions pile up fast. What goes in it? How much is enough? This guide covers what your family needs and how to organize it so anyone can find anything in seconds.
Why 72 Hours Matters
In a large-scale emergency, it can take about 72 hours for help to reach you. A hurricane hits a coastal county, a wildfire cuts off a neighborhood, or a winter storm knocks out power across three zip codes. First responders move fast, but they're covering a lot of ground.
That 72-hour window is yours. If your family can stay safe, warm, and hydrated for three days, you're ahead of most of your neighbors. And September is the month to act. It's peak hurricane season, the tail end of Western wildfire season, and the start of fall storms in the Midwest and Northeast.
What Every Kit Needs
Most store-bought kits are some water pouches, a mylar blanket, and a whistle in a drawstring bag. A real family kit covers five areas:
Water: One gallon per person per day, plus purification tablets or a filtration straw.
Food: Three days of high-calorie, no-cook food per person, like energy bars, trail mix, and vacuum-sealed pouches.
First aid: Gauze, a tourniquet, antiseptic, pain relief, your family's prescriptions, and a first aid reference card.
Communication and light: A hand-crank or battery-powered NOAA weather radio, a flashlight with extra batteries, and a backup phone charger.
Warmth and sanitation: Mylar blankets, a change of clothes per person, hygiene supplies, toilet paper, feminine care products, and diapers or wipes if you have little ones. Pre-packed kits often skip these, and they matter most on days two and three.
That's why building your own kit makes sense. When you pack it yourself, every pocket holds something your family will actually use.
Pack It So Anyone Can Use It
A kit is only as good as how fast you can find what you need. The youngest person in your house, or the one who's never opened the bag, should be able to find the right tool in seconds.
Give every category its own labeled compartment. Keep the flashlight, first aid kit, and charger in the most accessible pocket. Do a dry run. Ask your kids to find the purification tablets on their own. If they can't, reorganize. Store the bag near an exit or in the car, not buried in a storage unit. Built for Real Conditions
We're not a military brand, but the OTG DIY Kit is built to military-grade standards: fully waterproof welded construction, dual-coated 6000 TPU tarpaulin, YKK sealing zippers, and ISO 9001:2015 certified quality. Big-box kits use nylon that soaks through and zippers that jam under pressure.
You buy a 4x4 truck to do 4x4 stuff, not a Lamborghini. The OTG DIY Kit is the 4x4 of backpacks. It's a reliable, organized, waterproof kit for regular families facing real-world emergencies.
How Many Bags Your Family Needs
A kit only helps if you can carry it, and three days of water for two people weighs more than 40 pounds. Plan one bag for every two people:
1 to 2 people: One bag 3 to 4 people: Two bags, one per adult or one at home and one in the car 5 or more: Three bags, plus a plan for who carries what
Every purchase also supports OTG's Choose Impact program, which gives back to organizations that protect children, care for the earth, and strengthen community food systems.
Start Before Storm Season Peaks
The best time to build your kit was last spring. The second-best time is now, before you're watching a weather alert and waiting on a delivery.
Start with the bag. Everything else gets built around it. Add water and food first. They're the heaviest items and set your space limits. Layer in first aid, communication, and warmth. Give each its own labeled space. Do a family dry run. Everyone should know where the bag is and what's inside. Check it every March and September. Restock food, water, and batteries.
The OTG DIY Kit gives you a waterproof bag and a labeled ProPack organizer, so you can build a kit around your family's real needs. Start building yours today, and watch for code BLACKFRIDAY10OFF for 10% off this Black Friday.
