Buying Guide: What to Look For in the Best Emergency Blankets for Survival Kits
When I’m putting together a survival kit, the emergency blanket is one of those items that seems simple but has a huge impact. Picking the right one isn’t just about grabbing the first shiny packet you see. You need to think about a few key things to make sure it will actually work when you’re cold, wet, and really need it. Let me walk you through what I always check for.
First, material and durability are non-negotiable. Most blankets are made from a plastic film coated with a metallic reflecting agent, like aluminum. I look for terms like “rip-stop” or reinforced edges. A blanket that tears the first time you unfold it is worse than useless. Thickness matters too; a thicker polyethylene film will generally be more durable and provide better insulation than an ultra-thin, flimsy one, even if it takes up a bit more space.
Next, size and coverage. A standard 56″ x 84″ is common, but is that enough for you? If you’re taller or broader, you might feel cramped. Some blankets are extra-wide or even two-person size, which is great for covering more ground or wrapping up with someone else for shared warmth. Remember, the goal is to trap your body heat, and you can’t do that if the blanket is too small to wrap around yourself properly.
Then there’s the intended use. Am I stuffing this in my glove compartment, my hiking daypack, or a full-blown bug-out bag? For ultra-light backpacking where every ounce counts, a compact, featherlight model makes sense. For my car kit, I might prioritize a heavier-duty, reusable blanket or even a insulated thermal blanket that can handle being used multiple times. I also consider multi-function blankets; some have grommets for use as a shelter tarp, or a matte side for signaling. Finally, don’t forget packaging. It should be sealed in a sturdy, waterproof pouch that I can easily find and open with cold, clumsy fingers. By thinking through these points, you can confidently pick one of the best emergency blankets for survival kits that fits your specific needs.
FAQ
How is an emergency blanket different from a regular blanket?
An emergency blanket, often called a space blanket, works completely differently. A regular blanket insulates by trapping warm air in its fibers. An emergency blanket is a radiant barrier; its metallic surface reflects your body’s infrared heat radiation directly back to you. It doesn’t provide insulation from the air temperature itself, but it’s incredibly effective at stopping the heat you’re already producing from escaping. That’s why they’re so lightweight and compact, but also why you need to seal it tightly around you to work.
Can I reuse an emergency blanket?
This depends heavily on the quality. The super-thin, inexpensive models are really designed for single-use. They crease easily, and those creases can become tiny tears. However, many higher-quality blankets made from thicker, more durable material are absolutely meant for multiple uses. I always check the product description. If it says “reusable” or is marketed for camping beyond just survival, it’s a good bet. After use, just fold it carefully and try to store it back in its pouch.
Why are some blankets silver on both sides and others have a gold side?
The classic silver color is the standard reflective material. The gold side on some blankets is often a visual signal for rescue. The high-contrast gold color is more easily seen from the air against many natural backgrounds. Sometimes, the gold side is also treated to reflect more in certain light spectrums. In terms of warmth, there’s no major practical difference—both sides are reflective. The color choice is usually about the secondary function of visibility.
Do emergency blankets work in all weather conditions?
They are most effective in dry, cold conditions where radiant heat loss is a primary concern. They are still very useful in wet conditions because they are waterproof and will keep rain off you, which is critical. However, if you’re already wet, wrapping yourself in an impermeable layer can sometimes lead to condensation. In windy conditions, their real value shines because they block wind chill completely, but you have to secure them well so they don’t turn into a noisy, flapping mess.
Should I get a blanket or a sleeping bag liner for my kit?
This is a great question. For a pure survival kit, I always go with the blanket first. It’s more versatile—you can use it as a ground sheet, a shelter reflector, a signaling device, or to wrap around you. A sleeping bag liner only really works inside a bag. However, for a more comprehensive kit where weight is less of an issue (like a car kit), having both isn’t a bad idea. The liner adds direct insulation, and the blanket can be used on the outside of your bag for extra wind and water protection or as a standalone shelter component.
