Two years ago, wildfire evacuation orders gave my family just 20 minutes to leave our home. In that moment of near panic, I was profoundly grateful for a decision I'd made a year earlier: building well-equipped bug out bags for every family member. What could have been chaotic became ordered. While neighbors scrambled to gather essentials, we calmly collected our bags and valuables, knowing we had everything we needed to sustain us for the difficult days ahead.
A bug out bag isn't just another emergency prep checkbox—it's a tangible embodiment of the prepper's philosophy: hope for the best, prepare for the worst. In this guide, I'll share what I've learned through years of refining my own bug out strategy, including lessons from our actual evacuation experience, to help you build a personalized bag that could one day make all the difference for you and your loved ones.
What Is a Bug Out Bag & Why You Need One
The term "bug out bag" (or BOB) has military origins, referring to a pre-packed kit containing essential items needed to survive for at least 72 hours when evacuating from a disaster or emergency. It's also known by other names—go bag, evacuation kit, 72-hour kit—but the concept remains the same: a carefully curated collection of supplies that enables you to leave quickly and survive the immediate aftermath of an emergency.
The 72-hour timeframe isn't arbitrary. Emergency management agencies have determined this is typically how long it might take for organized assistance to reach affected areas following a major disaster. Your bug out bag bridges this critical gap, providing self-sufficiency during the most chaotic period.
Personal Insight
Before our evacuation, I had viewed my bug out bag as "emergency insurance"—something I hoped never to use. But during those 20 frantic minutes, its value became crystal clear. While we ended up at a Red Cross shelter for only two nights, having our own supplies meant we didn't tax already-limited resources. More importantly, the familiar items we'd packed provided my children with a sense of normalcy and comfort that was priceless amid the uncertainty.
In our increasingly unpredictable world, the scenarios that might require evacuation have expanded beyond the traditional emergency list:
- Natural disasters: Hurricanes, floods, wildfires, earthquakes, tsunamis
- Man-made emergencies: Chemical spills, industrial accidents, infrastructure failures
- Extended power outages: Particularly during extreme temperature events
- Civil unrest: When staying home becomes unsafe due to external factors
- Home emergencies: Gas leaks, structural damage, or localized flooding. A home fire safety plan might also necessitate evacuation.
The common thread in all these scenarios? They don't announce themselves with convenient warning. Even with monitored events like hurricanes, the actual moment of evacuation often comes with less notice than you might expect.
When to Bug Out vs. Shelter in Place
One of the most critical decisions in any emergency is whether to evacuate ("bug out") or remain at home ("shelter in place"). Making this determination requires clear thinking and good information—both of which can be in short supply during a crisis.
When to Bug Out
Situations when evacuation is likely the best choice
Official Evacuation Orders
When authorities issue mandatory evacuation orders, the decision is made for you. These orders aren't given lightly and usually indicate imminent danger.
Immediate Environmental Threats
Approaching wildfires, rising floodwaters, or tsunami warnings present clear and immediate dangers that often necessitate evacuation.
Home Is Compromised
Structural damage, gas leaks, or other issues that make your home unsafe leave evacuation as the only reasonable option.
Local Infrastructure Failure
When water, sewer, or other critical services fail in ways that make long-term habitation impossible, especially during extreme weather.
Security Concerns
Situations where remaining in place would expose you to danger from human threats or civil unrest.
When to Shelter in Place
Situations when staying put is typically safer
External Hazardous Conditions
Chemical spills, airborne hazards, or extreme weather events like tornados where being in transit increases your risk exposure.
Pandemic or Contagion Events
Situations where limiting contact with others is the primary safety protocol.
Localized Emergency with Functioning Infrastructure
Power outage or similar situation where your home remains safe and you have adequate supplies.
Civil Unrest at a Distance
When traveling would bring you into contact with dangerous situations that aren't directly threatening your home location.
No Clear Evacuation Route
When evacuation routes are clogged, dangerous, or unclear, sometimes waiting for better conditions is safer.
Pre-Decision Planning is Essential
The worst time to make evacuation decisions is during the stress of an emergency. Create clear decision criteria in advance. My family has pre-established triggers for different scenarios (e.g., "If the fire is within X miles and moving our direction, we evacuate"). This removes emotional decision-making when time is critical.
Choosing the Right Backpack
The foundation of any bug out bag is, well, the bag itself. This seemingly simple choice can significantly impact comfort, capacity, and ultimately, your mobility during an evacuation. After trying several options, I've found these considerations most important:
Capacity & Size
The ideal capacity falls between 40-65 liters for most adults. This provides enough space for 72+ hours of supplies without becoming unmanageably large. My personal preference is a 50-liter pack that balances capacity with mobility.
For children and those with physical limitations, scale down proportionately. My 10-year-old carries a 25-liter pack with lighter items, while my teenage son manages a 40-liter bag.
Comfort & Fit
A properly fitting pack distributes weight to your hips rather than shoulders. Look for:
- Padded hip belt that transfers 70-80% of weight to your hips
- Adjustable torso length (particularly important for women)
- Padded shoulder straps that don't dig into your neck or arms
- Sternum strap to prevent shoulder straps from sliding
- Ventilated back panel to reduce sweating
Remember: a comfortable 45L pack you'll actually wear is better than a painful 65L one you'll want to abandon.
Durability & Construction
Your bug out bag needs to withstand rough handling and potentially extreme conditions:
- Look for ripstop nylon or similar tough fabrics (at least 500-denier)
- Reinforced stitching at stress points
- Quality zippers (YKK preferred) with pulls large enough to use with gloves
- Water resistance or included rain cover
- Minimal external straps that could catch or tear
Organization & Accessibility
In an emergency, you need quick access to critical items without unpacking everything:
- Multiple compartments of varying sizes
- Top-loading main compartment with additional front or side access
- External pockets for water bottles and frequently used items
- Internal dividers or organization sections
- MOLLE webbing or attachment points for external gear (optional)
A Word About "Tactical" Bags
During our evacuation, I noticed an interesting pattern—those with extremely tactical-looking bags drew more attention than those with conventional hiking packs. While military-style bags offer excellent organization and durability, the "gray man" concept suggests blending in during emergencies. Consider whether a less conspicuous hiking backpack might better serve your needs, particularly in urban evacuation scenarios.
Essential Items to Include
While each bug out bag should be personalized, certain essential categories apply universally. Rather than providing a generic checklist, I'll share specific insights from my experience about what actually proved useful during our evacuation and subsequent days away from home.
Water & Hydration
Water is your most immediate need in almost any emergency. Aim for:
- Portable water: Carry at least 2 liters per person initially. We use 1-liter collapsible bottles that weigh almost nothing when empty.
- Filtration system: A compact water filter (like the Sawyer Mini or LifeStraw) extends your water supply indefinitely when natural sources are available. See our guide to the best water filtration systems for options.
- Purification tablets: These serve as backup to your primary filtration and treat issues filters can't handle, like viruses.
- Collection container: A collapsible 2-3 liter container gives you something to collect and treat water in.
Real-world lesson: During our evacuation, the shelter had limited potable water. Having our own filtration system meant we could use tap water without concerns, freeing up bottled water for those less prepared.
Food & Nutrition
Opt for dense, ready-to-eat foods that require minimal preparation:
- Calorie-dense bars: Emergency food bars pack significant calories in compact form.
- Freeze-dried meals: If you have water and heating capabilities, these provide more satisfying meals (but are bulkier).
- Trail mix and nuts: Provide healthy fats and protein with long shelf life.
- Jerky or pemmican: Shelf-stable protein sources.
- Instant coffee/tea packets: A psychological boost that shouldn't be underestimated. Consider items from your long-term food storage that are suitable for a BOB.
Real-world lesson: Pack at least one "comfort food" item per person. My daughter's favorite granola bars made a stressful situation slightly more normal for her.
Shelter & Clothing
Protection from the elements is critical, particularly in adverse weather:
- Emergency shelter: Lightweight options include emergency bivvy sacks, compact tarps, or ultralight tents.
- Extra clothing: One change of quick-drying, moisture-wicking clothes appropriate for your climate.
- Rain protection: Packable rain jacket and pants or poncho.
- Insulating layer: Compact down jacket or synthetic equivalent.
- Sturdy footwear: Either worn or packed, depending on your everyday footwear.
- Work gloves: Protect hands during evacuation, clearing debris, or setting up shelter.
Real-world lesson: Even though we evacuated to a shelter with a roof, temperature control was poor. Our extra layers made sleeping possible during unexpectedly cold nights.
Fire & Light
Multiple redundant options ensure you're never without these critical resources:
- Lighting: Headlamp (keeps hands free), compact flashlight, and chemical light sticks.
- Fire starting: Weatherproof matches, ferrocerium rod, and lighters (multiple methods).
- Tinder: Commercial fire starters or homemade options like cotton balls soaked in petroleum jelly.
- Candles: Provide both light and potential fire starting capability.
Real-world lesson: Headlamps proved invaluable during our evacuation for navigating poorly lit areas while keeping hands free to manage children and belongings.
First Aid & Medication
Build beyond the basic pre-assembled kit found in stores:
- Quality base kit: A good starting point, but customize for your needs.
- Prescription medications: At least a 7-day supply of all needed medications.
- Personal OTC needs: Pain relievers, allergy medication, digestive aids, etc.
- Additional wound care: Extra gauze, quality bandages, butterfly closures.
- Blister prevention/treatment: Often overlooked but critical if evacuation involves walking.
- Trauma supplies: Consider adding a tourniquet, chest seals, hemostatic gauze.
Real-world lesson: Having extra prescription medications meant we didn't need to worry about accessing pharmacies during our displacement. The peace of mind this provided can't be overstated.
Tools & Protection
Versatile tools that serve multiple functions maximize utility while minimizing weight:
- Multi-tool: Provides numerous functions in one compact package.
- Fixed-blade knife: More robust than a folding knife for heavy tasks.
- Paracord: Extremely versatile for repairs, shelter building, etc.
- Duct tape: Wrapped around a water bottle or pencil to save space.
- Whistle: For signaling (much more effective than shouting).
- Personal protection: According to your training, needs, and legal restrictions.
Real-world lesson: While our full-sized multi-tool was useful, the small pocket knife we carried proved sufficient for most evacuation tasks. Consider if a lighter option might meet your needs.
Communication & Navigation
Staying informed and oriented becomes critical during evacuations:
- Battery bank: Keep phones and small devices charged (minimum 10,000 mAh).
- Paper maps: Local, regional, and state maps that don't require batteries.
- Compass: Basic navigation tool that never needs charging.
- Emergency radio: Hand-crank or battery-powered for emergency broadcasts.
- Whistle and signaling mirror: For attracting attention and rescue.
- Emergency contacts: Physical list of important phone numbers and addresses.
Real-world lesson: Even with working cell phones, our paper maps proved essential during evacuation as cell networks became congested. They helped us identify alternative routes when main roads were blocked.
Documentation & Finances
Often overlooked but potentially crucial for recovery:
- Identification: Copies of ID, passports, birth certificates (digital and physical).
- Insurance information: Policy numbers, contact information, coverage details.
- Financial access: Some cash in small denominations, plus credit/debit cards.
- Property records: Deed/lease information and recent photos of property.
- Medical documents: Prescriptions, medical conditions, immunization records.
Real-world lesson: The small amount of cash we carried allowed us to purchase supplies when card systems were temporarily unavailable at local stores due to power fluctuations.
The items you leave out of your bug out bag are almost as important as those you include. Every ounce matters when you might need to carry your supplies for extended periods. Be ruthless about eliminating "nice to have" items that aren't truly essential.
Personalizing Your Bag
A truly effective bug out bag reflects your specific needs, location, and circumstances. The basic categories we've covered provide a foundation, but personalization transforms a generic kit into a lifeline tailored to your situation.
Personalization Factors
Key considerations for customizing your bug out bag
Geographic Location
Your climate and regional hazards should heavily influence your kit. Desert dwellers need sun protection and extra water capacity, while northern residents require more robust cold-weather gear. Our location in a fire-prone area meant we included N95 masks for smoke protection—which proved essential.
Physical Capabilities
Be honest about your fitness level and physical limitations. If you have mobility issues, emphasize gear that reduces the need to travel long distances on foot. After a knee injury, I added a collapsible trekking pole to my kit that would make extended walking possible.
Family Composition
Children, elderly family members, and pets all require specialized considerations. For my young daughter, we include comfort items (small stuffed animal, card game) that provide psychological support. Our elderly neighbor's bag contains a detailed medication schedule and spare glasses.
Medical Needs
Beyond basic first aid, address specific health conditions. Family members with asthma should have extra inhalers; diabetics need glucose monitoring supplies and snacks. My partner's allergy to bee stings means we carry an extra epinephrine auto-injector.
Skills & Knowledge
Your kit should leverage your existing skills and compensate for knowledge gaps. As an experienced camper, I carry less shelter material but more advanced first aid supplies, reflecting my comfort with improvising shelter but desire for better medical capabilities.
The Personal Item Rule
One strategy that's worked well for our family is what we call the "personal item rule": Each family member gets to select one non-essential personal item to include in their bug out bag, no questions asked. My son chose a small chess set, my daughter picked her journal, and I included a paperback book. During our evacuation, these items provided significant comfort and normalcy amid the chaos.
The psychological benefit of these small personal touches cannot be overstated. They transform an emergency kit from something you hope never to use into something that feels like a lifeline rather than just a survival tool.
Weight Considerations & Priorities
The eternal struggle with any bug out bag is balancing comprehensiveness with portability. A bag too heavy to carry becomes a liability rather than an asset, but one missing critical items could leave you vulnerable.
Weight Guidelines
As a general rule, your fully loaded bug out bag should not exceed 20% of your body weight, with 15% being a more comfortable target for most people. This means:
Ideal Weight
| Body Weight | Target Bag Weight |
|---|---|
| 120 lbs | 18-24 lbs |
| 150 lbs | 22-30 lbs |
| 180 lbs | 27-36 lbs |
| 200+ lbs | 30-40 lbs |
Special Considerations
- Children: Should carry no more than 10-15% of their body weight, with younger children carrying even less.
- Seniors: Generally aim for 10-15% of body weight, depending on physical condition.
- Physical limitations: Adjust downward based on mobility issues, existing injuries, or health conditions.
- Climate factors: Hot climates may necessitate carrying more water weight, requiring reduction in other areas.
After our evacuation experience, I realized my original bag was overbuilt at nearly 35 pounds. I've since refined it down to 28 pounds without sacrificing critical functionality by focusing on multi-purpose items and lightweight alternatives.
Prioritization Framework
When deciding what stays and what goes, use this three-tier system to evaluate each item:
Survival Essentials (Must Have)
Items that directly impact your ability to survive the first 72 hours: water, basic shelter, critical medications, navigation tools, minimal food, identification.
Functional Support (Should Have)
Items that significantly improve capabilities or comfort: additional clothing, comprehensive first aid, tools, communication devices, documentation, hygiene supplies.
Extended Comfort (Nice to Have)
Items that make evacuation more bearable but aren't critical: extra food variety, comfort items, advanced tools, backup supplies.
"Fill your bag in priority order: all Category 1 items first, then add Category 2 items until reaching 80% of your weight limit. The remaining 20% capacity can include select Category 3 items. This ensures you never sacrifice essentials for conveniences."
Maintenance & Rotation Schedule
A bug out bag that sits untouched for years gradually transforms from a valuable resource into a potential liability. Food expires, batteries corrode, medications lose efficacy, and seasonal clothing becomes inappropriate. A regular maintenance schedule ensures your bag remains ready when needed.
Seasonal Reviews (Quarterly)
I've found that aligning bug out bag maintenance with the changing seasons creates a natural reminder system. Each season brings different challenges and requirements:
- Spring Check: Update for warming temperatures, check for winter damage to items, prepare for storm and flood season
- Summer Check: Adjust for hot weather, ensure adequate sun protection, verify water capacity
- Fall Check: Transition to cooler weather gear, prepare for winter storms, check light sources as days shorten
- Winter Check: Ensure cold weather readiness, update for snow/ice conditions, check heating options
Expiration Tracking
Different items in your bug out bag have different shelf lives. My system uses a simple spreadsheet with replacement dates:
| Item Category | Check Frequency | Typical Lifespan |
|---|---|---|
| Food items | Every 6 months | 6 months - 5 years |
| Medications | Every 6 months | 1-2 years |
| Batteries | Annually | 2-3 years |
| Water | Every 6 months | 6 months - 1 year |
| Documents | Annually | Update as life changes |
Pack and Repack Practice
Beyond checking contents, I recommend completely unpacking and repacking your bag at least twice a year. This practice:
- Ensures you remember where critical items are located
- Provides opportunity to inspect items for damage or degradation
- Builds muscle memory for efficiently packing in an emergency
- Helps identify items that have migrated to daily use and not been replaced
After our evacuation, I instituted a family "bug out drill" where we practice grabbing our bags and essential items, timing how quickly we can be ready to leave.
The Rotation Strategy
Rather than letting items in your bug out bag reach expiration, consider implementing a rotation system where you use and replace items before they expire. For example, I rotate food items into our camping supplies about two months before their expiration date and replace them with fresh items. Similarly, batteries go into everyday use and get replaced with new ones in the bug out bag.
This approach ensures nothing goes to waste while keeping your emergency supplies fresh. It also makes maintenance feel less like a chore and more like a natural part of household management.
Common Mistakes to Avoid
Through personal experience and observing others during our evacuation, I've identified several common pitfalls that can undermine even the most well-intentioned bug out preparations:
Bug Out Bag Pitfalls
Common mistakes that compromise effectiveness
Overbuilding
The most common mistake is creating a bag too heavy to realistically carry. During our evacuation, I watched as people abandoned heavy bags after just a few blocks of walking. Be honest about your physical capabilities when determining weight.
Focusing on Gear Over Knowledge
No amount of equipment can compensate for lack of skills. The most valuable preparations are knowing how to use what you have. I've seen people with expensive water filters who didn't understand how to properly operate them under stress.
Ignoring Family Needs
Single adults often build bags suitable only for themselves, overlooking needs of children, elderly family members, or pets. Our neighbor forgot essential items for his young children, creating significant stress during evacuation.
Neglecting Psychological Comfort
Purely utilitarian bags address physical needs but neglect psychological welfare. Small comfort items provide disproportionate benefits to morale and stress management during crises.
Failing to Test Your Gear
Items that haven't been tested under field conditions may fail when needed most. Always test equipment before relying on it—our first emergency radio had reception too poor to be useful, something we only discovered during a practice drill.
Inaccessible Storage
Storing your bug out bag in a hard-to-reach location defeats its purpose. During our midnight evacuation, neighbors lost precious minutes retrieving bags from attics or buried in closets.
No Backup Plan
Relying entirely on your bug out bag without contingencies creates a single point of failure. Always consider what you would do if your bag were inaccessible or lost.
The One-Third Rule
A seasoned emergency responder shared a valuable principle with me after our evacuation: the One-Third Rule for resource allocation. When planning for emergencies, divide your resources three ways:
- One-third at home (for shelter-in-place scenarios)
- One-third in your bug out bag (for evacuations)
- One-third in your vehicle or secondary location (for situations where your home or bag are inaccessible)
This distribution ensures you're not putting "all your eggs in one basket" and provides redundancy for different emergency scenarios.
Example Application
For critical medications, keep the current month's supply at home, a 7-day supply in your bug out bag, and another 7-day supply in your vehicle's emergency kit. This ensures access to medication regardless of which emergency scenario unfolds.
Final Thoughts: Hope for the Best, Prepare for the Worst
Building an effective bug out bag isn't just about collecting gear—it's an ongoing process of assessment, refinement, and practice. It reflects an important mindset: proactive preparation without paranoia. As we experienced firsthand, the peace of mind that comes from knowing you're prepared for emergencies is invaluable, whether you need to use your preparations or not.
Remember that your bug out bag is a deeply personal tool that should evolve as your circumstances, knowledge, and skills change. There is no perfect, one-size-fits-all solution. The best bag is one tailored to your specific needs that you've practiced using and maintaining.
I encourage you to start where you are, with what you have. Even a partially equipped bug out bag is infinitely better than none at all. Begin with the essentials, learn through practice, and gradually refine your system over time. The goal isn't perfection—it's improvement and preparation that gives you options during uncertain times.
As the old saying goes, "The best time to prepare was yesterday. The second best time is today." Whatever your current level of preparedness, taking even small steps forward puts you in a better position than you were before.
True preparedness isn't about fear—it's about freedom. The freedom to face uncertainty with confidence, knowing you've taken reasonable steps to protect yourself and those you love.
