The Essential Emergency Blanket Buying Guide
Emergency blankets are small but mighty tools. They keep you warm when you need it most. Whether you are hiking, camping, or preparing for a power outage, knowing what to look for makes a big difference. This guide helps you choose the best one.
Key Features to Look For
Good emergency blankets share several important traits. These features determine how well the blanket works when you are in trouble.
- Heat Reflection: This is the most important feature. The blanket must reflect up to 90% of your body heat back to you. Look for blankets labeled as “Mylar” or “space blankets.”
- Size and Coverage: Check the dimensions. A standard size is usually around 52 x 84 inches. Make sure it is big enough to wrap around you completely.
- Durability/Tear Resistance: A flimsy blanket rips easily. Stronger blankets last longer and offer better protection from wind and rain.
- Compactness and Weight: Since you carry these for emergencies, they must be small and light. The best ones fold down to the size of a wallet.
Important Materials
Most emergency blankets use a very thin metalized film. Understanding the material helps you judge quality.
Mylar (BoPET)
Mylar is the standard material. It is a strong polyester film coated with a thin layer of aluminum. This coating reflects heat very well. Mylar is lightweight and waterproof. It is the material most survival experts recommend.
Other Materials
Some blankets use thicker, more durable plastic films. These might be slightly warmer or tougher but they lose the super-compact advantage of Mylar. For basic survival kits, stick to true Mylar.
Factors That Improve or Reduce Quality
Not all emergency blankets are created equal. A few small details separate the excellent from the useless.
Quality Boosters
- Thickness (Microns): Thicker Mylar (often 12 microns or more) is harder to tear. This extra thickness improves durability greatly.
- Sewn Edges: Blankets with reinforced or sewn edges last much longer than those with just glued or simple folded edges.
- Color Options: While silver reflects heat best, some blankets have an orange or green side. The orange side helps rescuers spot you during the day.
Quality Reducers
- Cheap Plastic Film: If the blanket feels like thin plastic wrap, it will tear immediately. Avoid these if you expect rough use.
- Poor Packaging: If the blanket is folded poorly inside its packaging, it may be difficult to unfold quickly in a stressful situation.
User Experience and Use Cases
How you use the blanket affects which type you should buy. Think about where you will keep it and what you might do with it.
In the Wild (Camping/Hiking)
Hikers use these as a backup shelter or ground cover. You can tie them between trees to make a lean-to. They also work well as a signaling device because the silver side shines brightly in the sun.
In the Home (Disaster Preparedness)
Home kits need blankets that stay ready for years. They are great for keeping family members warm during power outages when the furnace stops working. They are also useful for treating shock victims until help arrives.
Important Note on Breathability
Remember, these blankets trap heat very well. If you sweat a lot, the moisture gets trapped, making you wet and colder later. Use them to stay warm, but if you are exerting yourself, occasionally let some air in.
Frequently Asked Questions (FAQ) About Emergency Blankets
Q: What is the main purpose of an emergency blanket?
A: The main purpose is to prevent hypothermia. It works by reflecting your body heat back to you, keeping you warm in cold or windy conditions.
Q: Are these blankets reusable?
A: Yes, many Mylar blankets are reusable if handled carefully. If they do not tear severely, you can refold them and put them back in your kit.
Q: Can I use an emergency blanket as a rain poncho?
A: You can use it as a temporary shelter from rain, but they are not designed to be worn like a poncho for long periods. They tear easily when you move around a lot.
Q: Do they work if I wrap them silver side in or silver side out?
A: To reflect heat *to* your body, you should wrap the **silver side facing inward**, touching your clothing. If you need to signal rescuers, face the silver side outward.
Q: How long do emergency blankets last in a kit?
A: If stored properly away from extreme heat or moisture, Mylar blankets often have a shelf life of 5 to 10 years. Check the packaging date.
Q: Are they safe to use for pets in an emergency?
A: Yes, they work great for keeping small pets warm. Wrap them gently, just as you would a person, to prevent overheating or tearing the material.
Q: Is there a difference between a “space blanket” and an “emergency blanket”?
A: Not really. “Space blanket” is just a popular name for the original Mylar blanket developed by NASA. They are usually the same thing.
Q: Can I use these blankets to start a fire?
A: You cannot use them to start a fire directly. However, the shiny silver surface can sometimes be used to focus sunlight onto very dry tinder, acting as a crude solar reflector.
Q: Should I buy a bulkier, fabric-backed blanket instead?
A: Fabric-backed blankets are warmer and more durable. They are better for long-term camping. For a basic, grab-and-go survival kit, the lightweight Mylar is usually the better choice.
Q: What size should I get for a first-aid kit?
A: Look for a “bivvy sack” style or a standard 52 x 84-inch blanket. The bivvy style is a sleeping bag shape, which is often easier for an injured person to use quickly.
