Have you ever sat in a car during a sudden breakdown on a cold night and wished you had something lightweight that could stop the chill? That’s exactly the promise of an emergency blanket. These slim, reflective sheets can trap body heat, block wind, shed water, and even serve as a makeshift shelter. In short, they’re one of the highest value items you can pack because they weigh almost nothing but can make a real difference when the mercury drops or weather turns nasty.
Mylar blankets—often called space blankets—are made from a thin, reflective polyester film. They reflect up to 90% of radiated body heat back to the user, making them ideal for emergency situations. They fold down to the size of a wallet and weigh just a few ounces, which is why hikers and vehicle emergency kits often include them as standard gear.
Foil-lined blankets add a layer of insulation to the basic Mylar design. This makes them slightly bulkier but warmer and less noisy. If you want a balance between packability and sustained warmth, a foil-lined option is a smart pick—especially for longer waits in a stranded vehicle or for keeping someone warm during first aid scenarios.
For repeated use, consider fleece-backed or insulated reusable blankets. These are thicker and heavier, often weighing a few pounds, but they feel warmer and more comfortable against the skin. They work great at home during power outages or as an extra layer in your car for long winter trips.
Made for rugged conditions, heavy-duty survival blankets combine durable fabric with reflective coatings. They resist tearing, offer better windproofing, and often include grommets or straps so you can rig a shelter or anchor the blanket. These are popular among campers, search-and-rescue teams, and anyone building a comprehensive survival kit.
If you want choice and fast delivery, Amazon is a go-to. You’ll find everything from single Mylar sheets that weigh under an ounce to premium insulated blankets from specialty outdoor brands. Read reviews and look for package dimensions and pack weight in ounces so you buy the right model for your kit.
For outdoor-grade gear, REI stocks reputable brands with higher-quality materials. You’ll pay more than at a big-box store, but many of these blankets offer better durability, useful features like grommets, and clearer technical specs—important if you take winter hikes or camp in the backcountry.
Walmart carries affordable emergency blankets at neighborhood prices. They’re an excellent choice for bulk buys—such as stocking a car, office, or community center—because you can often pick up packs of several blankets without breaking the bank. Just double-check the spec sheet for size in inches and the weight in ounces.
Home improvement stores like Home Depot and Lowe’s sell emergency blankets suitable for home, car, and storm kits. Their selection frequently focuses on utility and affordability, and you can buy in person if a storm is on the horizon and you need gear right away. Look for heavier-duty options if you plan to use a blanket for shelter construction or rugged outdoor tasks.
Target mixes convenience with decent quality. Their emergency blanket options are often aimed at casual buyers preparing basic home or car kits. You’ll find both budget Mylar types and a few more comfortable fleece-backed models for around-the-house use.
If you fish, hunt, or work outdoors in cold weather, Bass Pro Shops and Cabela’s provide outdoor-focused survival blankets. These retailers tend to stock blankets with real-world features—like reinforced edges and durable fabric—that hunters and anglers appreciate when they need gear that stands up to repeated use.
Regional outdoor chains like Academy Sports carry a mix of price points, often with seasonal discounts on emergency and thermal blankets. These stores are great when you want to compare brands or ask staff for quick, experience-based advice on what will work best for trail use versus everyday emergency use.
When shopping, check the unfolded dimensions in inches to make sure the blanket will provide full coverage. A typical single adult Mylar blanket might measure 52 inches by 84 inches—big enough to wrap around most adults. For two people, look for blankets at least 84 inches long or consider buying two smaller blankets to layer.
Mylar reflects heat; it doesn’t generate it. Look for added insulation layers or a stated R-value for reusable blankets. R-values are more common on camping gear—higher is warmer. If you’re choosing between a foil sheet and an insulated blanket, ask yourself whether you need long-term warmth or a short-term, ultra-light option.
Weight matters if you backpack. Mylar space blankets often weigh under 2 ounces, while fleece-backed or insulated models can weigh from 8 ounces to several pounds. Decide whether your priority is carrying minimal ounces or having a more comfortable, reusable blanket.
Wind will strip heat quickly, so choose a blanket with windproof properties if you expect exposure. If you’re in wet environments, waterproofing is crucial. Durability comes into play if you’ll reuse the blanket; look for reinforced seams and higher-denier fabrics if you plan to depend on it regularly.
Keep an emergency blanket in the glove box or center console. If you get stuck, wrap it around your torso and head, and layer clothing on top. A Mylar sheet is great for quick warmth, but a fleece-lined blanket will keep you more comfortable during longer waits—especially if the temperature dips below freezing.
When the heat goes out, a reusable insulated blanket becomes priceless. Use it on top of your regular blankets or as a wrap when moving between rooms. For extended outages, create a small insulated space—like a tent of blankets over a couch—to trap heat more effectively.
Packing a Mylar blanket as a backup adds almost no weight to your pack but gives you emergency shelter and heat reflection. For planned cold-weather trips, bring a heavier insulated blanket or a sleeping bag rated for low Fahrenheit temperatures. Remember: layering is your best friend outdoors.
Reflective surfaces double as signaling tools. In daylight, the shiny side of a Mylar blanket can catch a rescuer’s eye. In first aid, blanket-wrapped victims retain heat better, so use them to prevent hypothermia until help arrives. Consider a bright-colored, coated option if visibility is a priority.
You can buy a basic Mylar blanket for under $5, while insulated reusable models range from $20 to $100 or more. Splurge when you need durability, comfort, or specialized features—like grommets for anchoring, tear-resistant fabric, or higher R-values. For community or workplace preparedness, low-cost Mylar blankets provide good coverage at scale; for individual safety and frequent outdoor use, invest in a mid- to high-end model.
SOL makes compact emergency blankets designed for backpackers and first responders. Their Mylar options are lightweight and often come in multi-packs, making them practical for group trips and emergency caches.
These brands are staples in first-aid and survival kits. Coghlan’s offers straightforward, affordable Mylar sheets, while Adventure Medical Kits focuses on combo solutions where a thermal blanket is paired with other emergency gear.
For people who camp in colder climates, brands like Therm-a-Rest produce higher-end insulated blankets and quilts. They feel more like traditional camping gear and are built for repeated field use.
If you’re outfitting a shelter, school, or workplace, buy in multipacks. Retailers like Walmart, Amazon, and Harbor Freight offer bulk options priced per unit far lower than single purchases. Make sure each blanket meets minimum size requirements and check the pack’s weight if storage space or transport is a factor.
Keep emergency blankets dry and out of direct sunlight when storing. Mylar can become brittle with long UV exposure. Store blankets in airtight bags or containers in a cool place, and check them annually for tears. For reusable blankets, wash according to the manufacturer’s instructions—usually a gentle cycle and air dry—to preserve coatings and insulation.
Before you buy, ask yourself: How will I use this blanket—once in a life-or-death emergency, regularly on the trail, or for household storm preparedness? Do I need extreme packability (ounces matter) or long-term warmth (pounds are acceptable)? What are the unfolded dimensions in inches, and will the blanket cover an adult or two? Finally, check for extra features like grommets, reinforced edges, and water resistance. These small details often determine whether the blanket is a one-time fix or a long-term lifesaver.
Emergency blankets are deceptively simple tools that punch well above their weight. Whether you buy a budget Mylar sheet to stash in every car or invest in a reusable insulated blanket for winter outings, the right choice depends on your needs: pack weight, weather exposure, and frequency of use. Shop at retailers like Amazon, REI, Walmart, Home Depot, and specialty outdoor stores to compare options and prices. With a few minutes of planning, you can add a compact layer of protection that could make a dramatic difference when trouble strikes.
