TL;DR
Pre-built emergency kits in the $50-100 range provide a starting point, not a complete solution — they consistently omit medications, quality first aid, and personal documents. Custom-built bags in the $150-300 range, assembled from quality individual components, outperform pre-built kits at equivalent or lower cost. The bag frame matters: buy quality, buy once.
Pre-Built Kit Comparison
| Kit | Price | Persons | Pros | Cons | |---|---|---|---|---| | American Red Cross Premium Kit | $55-70 | 2 | Recognizable brand, basic coverage | Low-quality components, no medical | | Wise Company 5-Day Emergency Pack | $100-130 | 1 | Includes food, reasonable organization | Heavy, food requires cooking, no first aid | | JUDY Emergency Kit The Go Bag | $90-115 | 2 | Well-organized, decent quality components | Expensive for contents, still missing medical | | Ready America 70280 72-Hour Kit | $45-60 | 2 | Cheap starting point | Very basic, survival blankets are inadequate | | Sustain Supply Premium Kit | $110-140 | 2 | Better quality components, comprehensive | Still missing prescription/medical needs |
Common commercial kit verdict: Buy one if you want a starting point, then immediately add: a quality first aid kit with tourniquet, your personal medications, copies of critical documents, a real water filter (not just tablets), and replace the survival blanket with an emergency bivy.
DIY Budget Build ($150 for 1 person)
A custom-built 72-hour bag at $150 outperforms most $100-130 commercial kits:
| Item | Cost | |---|---| | Pack (Osprey Daylite 13L or similar) | $40 | | Sawyer Squeeze water filter | $20 | | 2x 1-liter Nalgene water bottles | $15 | | Mainstay 2400-calorie emergency ration bar | $8 | | 2x Mountain House pouches + spork | $20 | | Emergency bivy (SOL Escape) | $25 | | BIC lighter + ferro rod | $5 | | First aid kit (Adventure Medical Kits Ultralight .7) | $20 | | Headlamp (Black Diamond Spot) | $40 | | Phone charger cable | included | | Documents pouch (waterproof) | $8 | | Total | ~$200 |
What's not included: phone and power bank (likely already owned), medications (personal), cash, navigation tools (compass + map, ~$20 additional), and communications equipment if desired.
Bag Frame Selection
The bag itself matters as much as what goes in it. You'll carry this potentially for hours or miles.
Quality hiking packs (recommended):
- Osprey Daylite: 13L, $40. Entry-level quality from a serious pack manufacturer.
- Osprey Stratos 24: 24L, $130. Excellent suspension, comfortable for longer carries.
- Gregory Baltoro/Deva: Full expedition pack for heavy loads if your kit is larger.
Budget military-style:
- 5.11 RUSH 24: 37L, $100-120. Durable, many pockets, popular. Heavier than an equivalent hiking pack.
- Condor Compact Assault Pack: 24L, $40-50. Reasonable quality at budget price.
Avoid:
- Unknown-brand "tactical" bags under $30 — straps fail, zippers break
- Drawstring bags or non-framed packs for loads over 15 lbs
- Bags without padded hip belts for loads over 25 lbs
Scaling by Household Size
A single-person 72-hour bag is the most efficient. Household scaling:
Two adults: Each carries an individual bag. Share heavy items (one water filter, one stove, one large tarp) to reduce duplication weight.
Two adults + young children: Adults carry full individual bags plus children's essential items (food, clothing, medications). Each child old enough carries a small age-appropriate pack (5 lbs maximum for young children).
Two adults + teenagers: Teenagers (14+) carry near-full individual bags. Split family shared items (tarp, stove, water filter) across multiple bags so no one bag is irreplaceable.
The critical rule: If you're separated from your bag, you should not be helpless. Every bag should contain that person's minimum survival needs (water, warmth, first aid, communication). Don't put all the water in one bag and all the food in another.
What Actually Gets Used
Research on disaster evacuations and real-world use shows:
Used most frequently:
- Water and purification
- Phone charger and power bank
- Medications
- Cash and documents
- First aid
- Dry clothing and footwear
Used rarely:
- Fire-starting tools (fires are rare in most evacuation scenarios)
- Most tactical tools
- Extensive navigation equipment (usually cell service or known routes are available)
This doesn't mean those items should be removed — low-frequency use items are often life-critical in the scenarios where they're needed. But it informs weight trade-offs: water and first aid deserve full weight budget; a heavy survival knife set may not.

Frequently Asked Questions
Should I buy a pre-built kit or build my own?
Build your own if you're willing to spend the time. Pre-built kits typically include low-quality versions of critical items, omit category-specific needs (medications, personal documents, specific food preferences), and are assembled to a price point rather than a capability standard. A custom-built bag using quality components from individual purchases usually weighs less, performs better, and contains exactly what you need for your scenario. Pre-built kits are acceptable as a starting point that you immediately supplement and customize.
What do commercial emergency kits consistently omit?
Critical medications (prescription and OTC), personal documents, meaningful first aid (most include basic bandages but not tourniquets or wound packing), quality water filtration (they include tablets but not filters), and cash. They also consistently include low-quality survival blankets (Mylar sheets that tear immediately) instead of quality emergency bivies, and toy-quality tools.
Are tactical bags better than hiking packs for bug-out use?
For most civilian bug-out scenarios, a quality hiking pack is better than a tactical bag. Hiking packs are designed for carrying weight comfortably over distance — which is exactly what a bug-out bag needs to do. Tactical bags look purposeful but are designed for military load carriage that differs from civilian evacuation scenarios. Exception: if your bag will be stored in a vehicle and needs to look unremarkable, a plain bag may be preferable to a tactical-looking pack.
