72-Hour Kit

Everything starts with a bag. A durable 30–40L backpack fits your full 72-hour kit and leaves room to adjust. Don’t overthink it — a solid JanSport or Osprey pack gets the job done.

This is the most important macronutrient category that most people completely ignore when building a kit. In a crisis, your body shifts toward fat-burning mode — whether you want it to or not. Stress hormones, disrupted sleep, reduced caloric availability, and elevated exertion all push your metabolism in that direction.

Healthy fats are calorie-dense (9 calories per gram versus 4 for carbs or protein), stable at room temperature, and require zero preparation. A single packet of almond butter delivers around 180 calories. A single pouch of olive oil delivers over 200. Per ounce and per unit of pack space, nothing competes.

Protein preserves muscle tissue, supports immune function, and keeps you cognitively sharp under prolonged stress. The hard truth is that clean, shelf-stable protein is genuinely difficult to find. Most commercial jerky contains significant added sugar, nitrates, and synthetic preservatives.

I lean on Chomps and Archer because they hold to a clean label and I actually enjoy the taste — both matter for a kit you’ll actually rotate through. Tuna pouches are chronically underrated: no can opener required, solid fat content, and a 3–5 year shelf life. SOS Ration Bars serve as the backstop — Coast Guard approved, five-year shelf life, pure caloric density when everything else is gone.

Carbohydrates aren’t the foundation of crisis nutrition — fats and protein are. But simple carbs serve a specific, important function: fast, accessible energy when your body is running hot and needs rapid fuel. Think of them as the kindling, not the log.

Honey is my preferred source. It’s natural, shelf-stable for an essentially indefinite period, and has documented antimicrobial properties that extend its utility beyond just food.

Most people never think about electrolytes when building a kit. This is a mistake that can turn a manageable situation into a dangerous one faster than almost any other oversight.

Here’s what most people miss: you can drink water all day and still be functionally dehydrated if you’re not replacing electrolytes. Sodium, potassium, and magnesium govern nearly every critical body function — muscle contractions, nerve signaling, fluid balance, blood pressure, and cardiac rhythm.

Rule of thumb: one LMNT packet per person per day at minimum under stress. Double that if physically exerting or in high heat.

One gallon per person per day is the minimum baseline. That’s three gallons per person for a 72-hour kit. Collapsible water jugs are ideal — they store completely flat when empty and take up virtually no space. Fill them when you need to activate your kit, not before.

Pair the jugs with a water filter straw. Quality filters can process up to 100,000 gallons from virtually any water source — a pond, a stream, a puddle. This single item converts a contaminated water source into safe drinking water and weighs only a few ounces.

The water filter is your backup plan. The collapsible jugs filled from your home tap are your primary plan. You need both.

The tourniquet covered in the EDC section is the single highest-impact medical item in this entire guide — and it lives on your body, not in this bag. For the 72-hour kit itself, the goal is a solid baseline first aid capability: control minor bleeding, cover wounds, manage basic symptoms, and protect both you and anyone you’re treating.

Add basic OTC medications appropriate for your household: pain reliever, antihistamine, antidiarrheal, and any prescription medications for a 72-hour extension. This is a starting point. As your training grows, your medical kit should grow with it.

A hands-free headlamp that clips to a hat brim — brighter and longer-lasting than your phone flashlight, and it keeps both hands free for actually doing things.

A quality multitool and a baseplate compass are staples. The multitool handles everything from cutting paracord to tightening a loose screw. The compass works when your phone doesn’t.
