Mochila de 72-Hour: The Definitive Guide to the Survival Kit Recommended by the EU

Quick summary: on March 26, 2025, the European Commission published the EU Preparedness Union Strategy and for the first time officially recommended that every household have a 72-hour emergency kit. A month later, on April 28, the Iberian Peninsula experienced the biggest power outage in its recent history. In this guide, we show you exactly what to pack in your 72-hour backpack, how to organize it by modules, which products to choose, and how much it should cost to put yours together.

What is the 72-hour backpack (and why 72 and not some other number)

The Backpack for 72 hours also called bug out bag (BOB), evacuation kit or emergency backpack—is a pre-prepared pack that contains everything needed to keep a person alive, with water, food, shelter, communication, first aid, and documentation for three full days in a crisis situation: a prolonged power outage, a DANA, a wildfire requiring evacuation, a health crisis, or any other scenario in which you have to leave home quickly or end up without basic services.

The figure of 72 hours is not arbitraryThree days is the average time that European authorities and emergency services consider necessary to restore basic services, allocate resources, and reach affected populations after a large-scale crisis. Before 72 hours, in many real-life situations, you will depend exclusively on what you have with you.

Here comes the key detail: The European Commission did not invent the concept, but it did make it official. On March 26, 2025, Commissioner Hadja Lahbib presented the EU Preparedness Union Strategy with this phrase, quoted verbatim in the official statement:

"Preparedness must be woven into the fabric of our societies — everyone has a role to play. Today's threats are fast, complex, and interconnected."

— Hadja Lahbib, European Commissioner for Preparedness and Crisis Management, March 26, 2025

That same day, Lahbib posted a video titled "What's in my bag: Survival Edition" showing his own 72-hour backpack. The clip went viral. And a month later, on April 28, the Iberian blackout hit: for several hours (and in some areas almost a full day), millions of people saw firsthand that the supermarket card terminal doesn’t work without power, that a phone without signal is an expensive paperweight, and that three liters of water for a family of four run out in an afternoon.

The most searched question on Google Spain in the early hours of April 29 was not political. It was: What to carry in an emergency backpack. If you've made it here, you're probably part of that question. Let's give it a technical answer.

Who really needs a 72-hour backpack

Spoiler: you. But it’s worth debunking the idea that this is something for retired military types or "bunker nerds." The real profile of a 72-hour backpack user in Spain in 2026 is much more diverse:

• Urban families with children in DANA-prone areas (Valencia, Murcia, Levante, eastern Andalusia).
• Security personnel, military, and police who needs a personal kit outside the service team.
• Workers with long commutes (sales reps, carriers, field technicians) who may become isolated.
• Residents of rural areas prone to wildfires or snowfalls that cut them off.
• Outdoor enthusiasts (hiking, hunting, bushcraft) who already have some of the gear and only need to organize it.
• Any home that he remembers April 28 and has thought this can't catch us off guard again.

If you identify with any of these profiles—or simply live in Spain in 2026—the 72-hour backpack is the household investment with the best cost-to-safety ratio you can make this year.

Choosing the right backpack: the container matters

Before putting anything inside, you need to choose the container. A 72-hour backpack it is not a weekend hiking backpack nor an urban travel backpack. You need specific features:

• Capacity from 30 to 45 liters for an adult. Anything less is not enough for 3 full days; anything more will weigh too much to evacuate on foot.
• MOLLE system on the exterior to attach modular pouches (first-aid kit, canteen, flashlight) and reorganize the load based on the situation.
• Durable materials: 500D or 1000D Cordura, reinforced stitching, YKK zippers. A broken strap in the middle of an evacuation is the worst possible surprise.
• Subtle color: olive green, Coyote, Ranger green, Multicam, or black. Avoid bright colors; in a crisis you don't want to draw attention.
• Smart compartmentalization`
• Lumbar belt and sternum strap to transfer weight to the hips on long hikes.

The contents of your backpack, by module: the 7 essential blocks

The most professional way to organize a 72-hour backpack is by functional modules, not just throwing everything in loose. This lets you find what matters in seconds when there's low light, stress, or urgency. These are the 7 modules you need to include:

1. Hydration: the most critical factor

The water is, without question, the most important and the heaviest element. The golden rule is 3 liters per person per day, which makes 9 liters for 72 hours. Carrying 9 liters on you is unfeasible—they weigh 9 kg in water alone—so the real strategy combines two things:

• Bottled water to get started: 1.5–3 liters in the backpack itself, plus a reserve in the car or at home. The PRO RATION line from Adventure Menu, for example, includes sterilized water with a shelf life of up to 50 years, one of the most stable solutions on the market.
• Water purification system: a Sawyer- or LifeStraw-type carbon filter, water purification tablets, and/or a metal pot for boiling water. With this, you can turn any natural source into safe drinking water.
• Canteen or hydration bladder to carry water while you're on the move.

2. Nutrition: the block where beginners make the most mistakes

This is where most amateur bug-out bags fail. Cans of tuna are not a solution: they weigh a lot, take up space, rust, and the backpack becomes unmanageable from 7–8 kg onward. For 72 hours, you need food that meets four criteria: high calorie density, minimal weight/volume, long shelf life, and minimal preparation.

The two technical solutions that meet all of that are the freeze-dried servings and the self-heating sterilized rations. They are not competing: they are complementary, and it is advisable to combine them.

Option A — Freeze-dried servings: Tactical Foodpack

Tactical Foodpack is the Estonian brand founded by Sverre, a former medic in the Estonian Special Operations Forces. Its rations are 100% freeze-dried, with no preservatives or artificial flavor enhancers, with a shelf life of up to 8 years. Each pouch weighs between 80 and 145 g and provides between 400 and 800 kcal per serving once rehydrated. You only need hot water and 8–10 minutes of waiting. If we take a closer look at the brand, we’ve covered it in depth in this article: Tactical Foodpack: your best ally in emergency food, combat rations, and outdoor adventures.

For a 72-hour backpack, we recommend a basic pack of 6 servings Tactical Foodpack (two main meals a day for three days), supplemented with freeze-dried snacks (apple, cheddar cheese) and an energy isotonic drink from the same brand to replenish salts.

Option B — Sterilized servings: Adventure Menu PRO RATION

Adventure Menu PRO RATION it is a different line, and for many evacuation scenarios it is the absolute best choice. They are rations sterilized and ready to eat (not freeze-dried): they do not need water to prepare, they come already hydrated. You can eat them cold directly from the package if the situation requires it, or heat them with the flameless self-heating bag included in the system. They have a shelf life of up to 15 years in the servings and up to 50 years in the sterilized water included with the packs.

The difference between freeze-dried and sterilized is strategic: we’ve devoted an entire article to explaining it in Sterilized vs. freeze-dried. Summary: if you don't know whether you'll have water or fire when you need them, PRO RATION is the safest option. If you want to minimize weight and know you'll have water, Tactical Foodpack freeze-dried meals are the better choice.

The optimal combination for a 72-hour backpack

The ideal 72-hour food kit that we recommend to our customers at SERMILITAR is:

• 1 × Survival Pack Menu I PRO-RATION by Adventure Menu: the survival pack that comes complete with sterilized ready-to-eat rations + water + energy snacks, all in one box. It’s the backbone of the kit.
• 3–6 × Tactical Foodpack freeze-dried rations to your liking (carbonara, mushroom risotto, beef stew, chicken curry, vegetarian options).
• 1 × self-heating bag (Adventure Menu or Tactical Foodpack) in case you ever don’t have access to fire but still need to heat it.
• 1 × NRG-5 serving as a reserve, with a shelf life of up to 20 years, as a caloric lifeline for the last day.

If you want to see all the options, in Complete emergency food collection Here is the catalog organized by brand and type. And if you prefer the fastest, most professional solution for the food section of your backpack, we recommend the ready-made pack directly: Adventure Menu PRO RATION — full range.

3. Energy and lighting

When the power goes out, the first real problem isn’t the fridge: it’s not being able to see after 19:00 in winter. The energy module must include:

• LED headlamp headlamp with accessible batteries (hands-free, essential).
• Tactical handheld flashlight MIL-TEC MISSION 1000 type or similar, with at least 500–1000 lumens and a rechargeable option.
• Replacement batteries AA and AAA, stored separately from the device to prevent leaks. Consider lithium batteries, which last longer in the cold.
• External battery (power bank) at least 10,000 mAh to charge your phone 3–4 times.
• Foldable solar charger optional for unlimited autonomy.
• Chemical light sticks (Cyalume) 12 hours of emergency lighting without batteries.

4. Communication and information

During the 28-A blackout, the most disturbing thing was not the darkness: it was the misinformation. Without mobile phones, radio, or networks, people did not know what was happening or how long it would last. To avoid this:

• Portable FM/AM radio with hand crank (and optional solar panel). No batteries, no plugs, you always receive official information.
• Written family contact plan (not just saved on your phone): key phone numbers, physical meeting point, address of a family member outside the affected area.
• Walkie-talkies PMR446 Free use in Europe if you are part of a group or family that could become separated in a crisis.
• Metal whistle for high-intensity signage.
• Signaling mirror for outdoor use.

5. Shelter, refuge, and rest

The cold kills faster than thirst or hunger. In a 72-hour backpack, you won’t carry a tent, but you do need to cover the shelter module:

• Emergency thermal blanket: weighs 50 g, takes up as much space as a handkerchief, and can save your life. Carry at least two.
• American-style poncho liner blanket (MIL-TEC US Army) if your backpack allows it: 210 × 150 cm, thermal, retains body heat, can be used as an improvised sleeping bag or poncho liner.
• Tactical waterproof poncho Texar Ripstop type: protects you from rain, works as an improvised shelter, and as a carry bag.
• A full change of clothes sealed in a waterproof bag: dry technical socks (this detail is critical), thermal shirt, underwear.
• Wool or fleece hat and thin gloves. A lot of heat is lost through the head and hands.

6. Health and first aid

A well-stocked first aid kit is the difference between a scare and a medical emergency. For 72 hours, you need a IFAK (Individual First Aid Kit) or a medium-sized MIL-TEC first aid kit that includes:

• Sterile gauze, dressings, elastic bandages, medical tape, and assorted adhesive bandages.
• Antiseptic (chlorhexidine or povidone-iodine), single-dose saline solution.
• Trauma shears, forceps, nitrile gloves.
• Certified CAT tourniquet and hemostatic gauze (if you have training to use them).
• Personal medication: pain relievers (paracetamol, ibuprofen), antidiarrheal, antihistamine, oral rehydration salts.
• Chronic medication for 5–7 days If you are taking medication (blood pressure, diabetes, asthma, blood thinners…). This point is often forgotten and is vital.
• Insect repellent and sunscreen in a small format.

We recommend basic first aid training (Red Cross, Civil Protection) if you want to take your 72-hour backpack seriously. Having a tourniquet without knowing how to use it is worse than not having one.

7. Tools, fire, and documentation

The last module, but no less important, brings together what allows you to solve problems:

• Multi-tool M-TAC or Leatherman multitool type: pliers, wire cutters, saw, screwdriver, blade. It is the modern Swiss Army knife of the prepper.
• Fixed tactical knife or folding knife of good quality, with case and clip.
• Spark lighter (ferrocerium) + Bic lighter + waterproof matches: fire redundancy. Three different systems so none of them fail you at the same time.
• Duct tape (duct tape): fixes everything from a torn boot to a broken piece of glass. 5 M rolled up takes up almost no space.
• Paracord 550 (15–30 meters): countless uses, from securing a tarp to immobilizing a fracture.
• Large trash bags: improvised poncho, water collection, ground insulation.
• Plastified documents: copy of your ID card, health card, Social Security number, key contacts, address of a family member outside the area, car and home insurance details.
• Cash: at least €100 in small bills (€5, €10, €20). On 28-A, ATMs and POS terminals were not working.
• Encrypted USB with digital copies of important documents.

How much does it cost to put together a 72-hour backpack

The realistic budget for a 72-hour backpack well made for an adult, buying new, quality tactical gear, it usually ranges between 200 and 400 €. If you make use of items you already have at home (flashlights, knives, technical clothing), you can bring it down to 120–180 €.

Typical investment breakdown:

• Tactical 35–45L backpack: 60–120 €
• Block food supply (Survival Pack PRO RATION + Tactical Foodpack rations): 70–130 €
• Front light (headlamp + flashlight + batteries + power bank): 40–80 €
• Hand-crank radio + walkie-talkies (optional): 30–80 €
• Shelter (American blanket + poncho + thermal blanket + change of clothes): 40–80 €
• MIL-TEC or 5.11 TacMed Flex IFAK Kit: 30–70 €
• Tools (multi-tool + knife + fire + paracord): 30–60 €

Compared to the average annual spending on dining out or streaming subscriptions, it’s a modest investment. And unlike those, this one doesn’t expire every month: a well-equipped 72-hour backpack with PRO RATION products (15-year shelf life) and Tactical Foodpack (8 years) stays ready almost an entire decade.

The 7 most common mistakes when packing a 72-hour backpack

1. Make it too heavy. A bug-out backpack for an adult in good shape should not exceed 10–12 kg. If it weighs 18 kg, you won’t carry it for more than 2 hours.
2. Fill it only with food and water. The need for water and food is critical, but without shelter, light, and a first aid kit, the other two lose value.
3. Buying expensive gadgets and forgetting the basics. A €200 knife is useless if you’re not carrying a €3 thermal blanket.
4. Do not test the equipment. A 72-hour backpack you’ve never carried, never opened, and whose rations you’ve never tried is an experiment, not a kit.
5. Forgetting chronic medication. It is the most serious error in profiles with ongoing medical treatment.
6. Do not include physical documentation. If your phone dies, without your laminated ID, key phone numbers written down on paper, and cash, you're screwed.
7. Store it in an inaccessible place. A bug-out bag in the storage room at the back of the garage is no use when you have 2 minutes to leave the house. It has to be near the front door.

Frequently Asked Questions About the 72-Hour Backpack

How much should my 72-hour backpack weigh?

Between 8 and 12 kg for an adult in good physical shape. Above 12 kg, prolonged walking becomes unfeasible. If you live in an urban area and your plan does not include traveling long distances on foot, you can afford more weight; if you live in a mountainous rural area, cut it down.

Where should I store the 72-hour backpack at home?

In an accessible place near the front door, known to all family members. The entryway closet, under the coat rack, or a drawer beneath the entryway console are typical locations. Never at the back of the storage room or in an attic. If you have to evacuate because of fire or flooding, you have 60–120 seconds to grab the backpack and leave.

Do the contents of the backpack expire? How often should I check?

Check the backpack at least twice a year, ideally when the clocks change (October and March). Check batteries, ration expiration dates, medication, the condition of clothing, and the water. Tactical Foodpack freeze-dried rations last up to 8 years; Adventure Menu PRO RATION sterilized meals, up to 15 years. Batteries can leak sooner; replace them annually.

Do I need one backpack per person or one for the whole family?

One per adult, no exceptions. Small children can share some of their parents' gear, but each adult must have their own self-contained pack. If the group gets separated in a crisis (something more common than it seems), no one should be left without supplies.

Can I eat Adventure Menu PRO RATION meals cold?

Yes. That is precisely the distinguishing advantage of the PRO RATION range compared to freeze-dried products. They come fully hydrated and ready to eat: if you don't have water, fire, or a self-heating pouch, you can eat them directly from the package. The texture and temperature won't be ideal, but they'll give you the calories and nutrients you need. That's exactly the scenario they were designed for.

Is it legal to carry a knife or multi-tool in a 72-hour backpack?

Yes, within the limits of Spanish Weapons Law. Knives and multi-tools with blades under 11 cm and without an automatic mechanism are perfectly legal for domestic, sporting, or professional use. For use in public spaces, it is advisable to be able to justify the reason (work, sport, emergency kit). Avoid prohibited models: double-edged blades, automatic butterfly-style mechanisms, or ballistic knives.

Do I need a different kit for the car?

Yes, ideally. The 72-hour car backpack can be a simplified version (less weight, more volume) focused on staying inside or near the vehicle: blanket, water, rations, flashlight, first-aid kit, jumper cables, warning triangles, reflective vest, and a tire repair kit. The Survival Pack PRO RATION are especially well suited for this purpose thanks to their 15-year shelf life: you put them in the trunk and forget about them for a decade.

The next step: build yours this weekend

If you’ve made it this far, you already have 80% of the knowledge you need. What separates prepared families from those who improvised on April 28 is just one thing: to have done it. The perfect emergency kit that you don't assemble is useless; the imperfect emergency kit you have ready by the door can change the outcome of a real crisis.

At SERMILITAR, we have spent years equipping military personnel, police officers, private security forces, rescue professionals and, increasingly, civilian families who have understood the new European preparedness doctrine. If you want to put together your backpack with professional, reliable gear, we recommend starting with these three points:
