Emergency Warmth and Sleep Systems

Cold is one of the most dangerous aspects of extended outages and evacuations. The right warmth gear doesn't have to be expensive or heavy — but it does need to actually work.

Warmth gear serves two scenarios: staying warm at home during a winter outage, and staying warm away from home during an evacuation. The gear overlaps but the priorities differ slightly.

What to Look For

  • Emergency mylar blankets — the foil emergency blankets that fold to pocket size reflect up to 90% of body heat. Not comfortable for sleeping but genuinely effective. Pack two per person.
  • Sleeping bag — for go-bags or extended outages, a lightweight sleeping bag rated for your climate is among the most useful items you can own. Look for temperature rating, weight, and compressed size.
  • Packable synthetic or down layer — a packable parka or puffy jacket adds significant warmth for minimal weight and size.
  • Wool socks and base layers — wool stays warm when wet, unlike cotton. Worth the investment for emergency use.
  • Sleeping pad — even a foam pad provides significant warmth by insulating from cold floors.

What to Avoid

  • Emergency blankets used as sleeping bag substitutes for extended sleep — they're useful but not comfortable or practical for an entire night
  • Cotton-based warmth gear — cotton kills in cold and wet conditions
  • Summer sleeping bags if you live in a cold climate
