best emergency blankets for survival kits

When the temperature drops and your life is on the line, the right emergency blanket can mean the difference between an uncomfortable night and a fatal one. I have spent the last several years building, testing, and refining my own survival kits for everything from day hikes in the Appalachians to weeklong backcountry trips in the Rockies. Along the way I have tried, torn, frozen under, and repacked more mylar emergency blankets than I can count.

This guide covers the best emergency blankets for survival kits in 2026, ranking ten of the strongest options I and other preppers, hikers, and EMTs actually trust. Whether you are stocking a bug out bag, a car emergency kit, a home preparedness shelf, or a backpacking first aid kit, the choices below cover every budget, material, and use case worth considering.

Before we get into the individual reviews, you should know that not all emergency blankets are created equal. Cheap dollar-store mylar tears if you look at it wrong, while premium options from brands like Arcturus, SOL, and Titan can double as ground tarps, rain shelters, and rescue signals. I will also be linking out to a couple of related guides on our site, including our writeup on the best bivvy bags for emergency shelter and our picks for emergency preparedness gear like hand crank radios.

1. Swiss Safe 4 Pack Mylar Emergency Blankets

BEST VALUE

Pros

  • Effectively reflects and retains body heat
  • Lightweight and compact
  • Durable yet lightweight construction
  • Waterproof and versatile
  • Bonus space blanket included

Cons

  • Can puncture if not careful
  • Noisy crinkly material

I have kept a pack of Swiss Safe blankets in my car emergency kit for the past three winters and they have never let me down. The 12-micron aluminized polyethylene mylar is a noticeable step above the thin dollar-store stuff that rips before you even get it unfolded.

Each blanket measures 82 by 52 inches, which is enough coverage for most adults, and they fold down small enough to fit in a glove box, a jacket pocket, or a side pouch on a bug out bag. At just 1.6 ounces per blanket, you barely notice the weight on a long hike.

The reflective surface genuinely does retain body heat. On a 25 degree Fahrenheit night in my backyard test, wrapped properly with the silver side facing in, I stayed noticeably warmer than with no blanket at all. Swiss Safe claims 90 percent heat retention and based on my experience that number feels accurate for the first few hours of use.

The big selling point for me is value. You get four full-size blankets plus a smaller bonus space blanket in every pack. That is enough to outfit a family of four, stock a car kit, and still have spares for a hiking first aid kit. With nearly 18,000 reviews and a 4.7 star average rating, the consensus among buyers matches my own testing.

How It Handles Real-World Abuse

The mylar will puncture if you drag it across sharp rocks or broken glass, so it is not a replacement for a heavy duty tarp. For sitting on snow, wrapping a shock victim, or blocking wind in an improvised shelter though, these blankets perform exactly as advertised. They are waterproof, wind resistant, and quiet enough if you tape the edges down.

Best Use Case for the Swiss Safe Pack

This is the best emergency blanket for survival kits when you need quantity without sacrificing quality. Preppers love it for handing out at community events, parents keep them in school emergency kits, and EMTs often carry them as disposable patient wraps. If you want a reliable, affordable, and proven mylar blanket in bulk, start here.

2. Primacare HB-10 Emergency Mylar Thermal Blankets

BULK PICK

Pros

  • Great value for price
  • Waterproof barrier
  • Excellent heat retention
  • Lightweight and compact
  • Durable material

Cons

  • Noisy crinkly foil material
  • Quite thin
We earn a commission, at no additional cost to you.

The Primacare HB-10 is the blank canvas of the emergency blanket world. It is a straightforward, no-frills mylar foil blanket sold in a 10-pack, and it is the same style used by EMS professionals and marathon organizers. If you have ever been handed a silver foil sheet at the end of a cold morning race, this is likely what you got.

Each blanket measures 84 by 52 inches, slightly longer than the Swiss Safe, and they come individually folded so you can distribute them without a tangled mess. The mylar foil construction is designed to retain body heat in cold conditions or deflect solar heat in desert environments.

What makes the Primacare worth considering is the quantity. Ten blankets for the price of a single fast-food lunch is hard to beat if you are building multiple kits. I keep a few of these in the trunk, a couple in my hiking pack, one in the garage workshop, and still have spares to give to my neighbors for their own car kits.

The material is thin, no question. The tradeoff for that thinness is a weight of just a few grams per blanket and a packed size smaller than a deck of cards. You sacrifice durability for packability, which is the classic emergency blanket compromise.

What Buyers Actually Use Them For

Beyond emergency preparedness, reviewers use these for everything from lining pet shelters to blocking weeds in the garden to crafting reflective backdrops for photography. The mylar foil is genuinely versatile, which makes the 10-pack an even better value if you think creatively about secondary uses.

Durability Expectations

Treat these as disposable or semi-reusable. They will survive one careful use and can be folded back up if you are patient, but they are not designed for repeated heavy abuse. For a survival kit that you hope to never open, that is the right tradeoff.

3. Arcturus All-Weather Outdoor Survival Blanket

EDITOR'S CHOICE

Pros

  • All-weather protection
  • Durable 3-layer design
  • Lightweight and compact
  • Reinforced grommets for versatile use
  • Includes waterproof carry bag

Cons

  • More expensive than basic mylar blankets
  • Heavier than single-layer mylar blankets

The Arcturus All-Weather Survival Blanket is the one I reach for when I need an emergency blanket that can also function as a serious piece of gear. It uses a 3-layer design that sandwiches reflective mylar between rugged polypropylene layers, which means it will not shred the moment it touches a branch or a rock.

This is the best emergency blanket for survival kits when you want something reusable rather than disposable. I have used mine as a ground cloth under a tent, a wind block at a hunting camp, and an improvised lean-to shelter. The four reinforced grommets in the corners make it easy to rig with paracord, which is a feature almost no flat mylar blanket offers.

At 60 by 82 inches and about 1.4 pounds, the Arcturus is larger and heavier than basic mylar sheets. It still packs into the included waterproof carry bag at roughly the size of a softball, so it fits easily in a daypack or a vehicle kit without complaint.

The reflective side returns body heat toward you while the polypropylene outer layer blocks wind, rain, and snow. In my testing, sitting on cold ground wrapped in the Arcturus was dramatically warmer than sitting on bare mylar, largely because the 3-layer construction eliminates the conductive cold-transfer problem that ruins cheap blankets.

Why It Justifies the Higher Price

You are paying roughly three times what a basic mylar 4-pack costs, but you are getting a blanket that can replace a ground tarp, a shelter footprint, a wind screen, and a picnic mat. For anyone building a serious survival kit rather than a disposable grab-and-go bag, that versatility pays for itself fast.

Color and Signal Visibility

The red version is highly visible from the air and from a distance, which matters if you ever need to signal for rescue. Arcturus also offers camouflage patterns for hunters who want the opposite. Think about whether you want to be found or stay hidden before you choose your color.

4. PREPARED4X Emergency Mylar Poncho

WEARABLE PICK

Pros

  • Reliable rain and wind protection
  • Compact yet spacious fit
  • Advanced heat retention with reflective mylar
  • Lightweight and durable
  • Easily packable and reusable

Cons

  • May be too short for some users
  • Short sleeves
  • Can be noisy when walking
We earn a commission, at no additional cost to you.

The PREPARED4X poncho solves one of the most frustrating problems with flat emergency blankets: keeping them wrapped around you while you move. By integrating a hood and arm holes into the design, this poncho lets you walk, work, or hike while staying covered in reflective mylar.

I first tried one during a wet, windy scouting trip in the Cascades. Instead of awkwardly clutching a slippery blanket around my shoulders, I just slipped the poncho on and kept moving. The reflective mylar lining traps up to 90 percent of body heat while the outer layer sheds rain and blocks wind.

At double the thickness of standard emergency blankets, the PREPARED4X resists tearing better than typical mylar sheets. The 4-pack gives you enough to outfit a family or to stash spares in multiple locations.

The fit is generous enough to go over a backpack, which is a thoughtful detail for hikers. Some taller users note that the poncho only covers to the hips and the sleeves are short, so it functions more like a thermal shell than a full-length garment.

Mobility vs Full Coverage

This is the tradeoff you make with any poncho-style emergency blanket. You gain the ability to walk and use your hands, but you lose the full-body wrap that a flat blanket provides. For bug out scenarios where you need to keep moving, that tradeoff is worth it.

Noise Considerations

The mylar material does crinkle when you walk, which is a common complaint across all mylar products. If silence matters for your use case, consider wrapping the poncho over a softer base layer to muffle the sound.

5. QIO CHUANG Emergency Mylar Thermal Blankets

BUDGET PICK

Pros

  • Great value for price
  • Individually packaged for easy storage
  • Reusable and durable
  • Multiple uses beyond emergency blanket
  • Good heat retention

Cons

  • Some users report receiving used items
  • Material is thin but tear-resistant
We earn a commission, at no additional cost to you.

The QIO CHUANG 4-pack is one of the most affordable ways to put legitimate emergency blankets into multiple kits without cutting corners on quality. Each blanket is individually folded, wrapped, and sealed, which makes distribution and storage clean and simple.

I appreciate the slightly larger 84 by 55 inch dimensions, which gives more wrapping coverage than standard 52-inch-wide blankets. The orange color is also a bonus for rescue visibility compared to plain silver options.

The aluminized mylar retains up to 90 percent of body heat, matching the performance claims of much more expensive brands. In practice, the heat retention feels comparable to Swiss Safe and Everlit in side-by-side backyard testing.

With over 8,000 reviews and a 4.7 star average, the value proposition here is hard to argue with. These are the blankets I recommend to friends who are just starting to build their first car emergency kit and do not want to spend a lot before they know what they need.

Storage and Distribution

The individual packaging means you can hand these out at scout meetings, office preparedness trainings, or community events without dealing with a tangled bulk stack. Each one is ready to use straight out of the wrapper.

Long-Term Reusability

These are marketed as reusable, and with careful handling they will survive several uses. They are not in the same durability class as the Arcturus or SOL heavy-duty options, but for the price the lifespan is reasonable.

6. Don't Die In The Woods Extra Thick Emergency Blankets

TOUGHEST MYLAR

Pros

  • Thicker and more durable than standard emergency blankets
  • Compact storage with carabiner included
  • Reflects up to 90% of body heat
  • Waterproof and windproof
  • Reusable if handled carefully

Cons

  • Mylar does not breathe and can cause condensation
  • Cannot be refolded into tiny storage bag once opened
  • Some users report thinner than expected

The name says it all. Don't Die In The Woods makes what they call the world's toughest emergency blanket, and after putting a set through their paces I am inclined to agree that they are a meaningful step up from basic mylar.

The secret is their HeatFlex mylar at 28 microns thick, which is more than double the thickness of standard emergency blankets. That extra material translates directly into tear resistance. You can stretch, pull, and even puncture a small hole without the entire blanket splitting apart like cheap foil.

I took one of these on a three-day backpacking trip and used it as an improvised ground cloth, a wind block around my cooking area, and an overnight wrap. It survived all three uses with only minor creasing, which is more than I can say for the budget blankets I have tried in the past.

The 4-pack comes with a carabiner for clipping to the outside of a pack, which is a small but appreciated touch. Each blanket weighs just 2.5 ounces, so the entire set adds barely over 12 ounces to your load.

Condensation Management

Because the mylar does not breathe, condensation can build up inside if you wrap it tightly for hours. The solution is to leave a small gap for ventilation or to use the blanket as an outer shell over a breathable layer. This is a known issue with all non-breathable emergency blankets, not unique to this brand.

Refolding Reality Check

Once you open and unfold one of these, getting it back into the original tiny storage bag is nearly impossible. Plan to repack loosely into a larger stuff sack or zip-top bag after the first use.

7. EVERLIT Survival Emergency Mylar Thermal Blankets

VETERAN-OWNED

Pros

  • Designed by NASA with dual-sided thermal material
  • Very lightweight at 2 ounces per blanket
  • Compact enough for any kit
  • Retains up to 90% of body heat
  • Multi-purpose versatility

Cons

  • Hand wash only
  • Single-use in extreme conditions
  • No grommets for easy hanging

EVERLIT is a veteran-owned company, and that background shows in the way they think about survival gear. These blankets are designed to be no-nonsense, mission-ready, and affordable enough to stock across every kit you own.

Each blanket is a dual-sided thermal sheet made from NASA-inspired mylar, measuring 82 by 58 inches and weighing just 2 ounces. The dual-sided design means you can use either orientation depending on whether you want to retain heat or deflect it, which is useful in both winter and desert environments.

In my hands-on comparison, the EVERLIT blankets felt comparable in thickness and reflectivity to the Swiss Safe and QIO CHUANG options. The heat retention claim of 90 percent is consistent with what I felt during a 30 degree Fahrenheit backyard wrap test.

The multi-purpose pitch is genuine. I have used these as emergency ponchos by cutting a head hole, as improvised shelter walls with paracord, and as a reflective inner liner for a debris hut. At this price point for a 4-pack, you can afford to sacrifice one for experimentation.

Warranty and Customer Support

EVERLIT backs their products with a 1-year satisfaction warranty and emphasizes responsive customer support. Several reviewers mention receiving quick replacements for damaged or missing items, which is reassuring when you are buying gear sight unseen.

Best Kit Integration

These are ideal for tucking into the side pockets of a bug out bag, the glove compartment of a vehicle, or the outer mesh of a daypack. Their slim profile and negligible weight mean there is no good excuse to leave home without one.

8. TITAN Survival Premium Mylar Survival Blankets

PREMIUM PICK

Pros

  • Veteran-owned company with excellent customer service
  • Thicker than typical emergency blankets
  • Camouflage pattern available
  • Lifetime guarantee
  • Multiple sizes and color options

Cons

  • Limited stock availability
  • Designed primarily for single-use emergencies
  • 17-micron thickness thinner than some alternatives
We earn a commission, at no additional cost to you.

TITAN Survival is another veteran-owned brand that preppers and outdoor enthusiasts speak highly of, and their premium mylar blankets come with a lifetime guarantee that very few competitors offer. The 5-pack gives you one extra blanket compared to most bundles.

At 17 microns thick, the TITAN blankets sit between standard thin mylar and the heavy-duty Don't Die In The Woods options. The biaxially-oriented PET material is tear-resistant, waterproof, and windproof, with a reflectivity that retains up to 90 percent of body heat.

I tested the Woodland Camo version, which is popular with hunters and tactical users who want to stay concealed. TITAN also offers Safety Orange and Signal Panel colors for those who want maximum visibility for rescue scenarios. Having that choice is a real advantage.

The lifetime guarantee is the standout feature. If a blanket fails under normal use, TITAN will replace it. That kind of confidence is rare in the disposable emergency blanket category and it is a major reason the brand has earned recommendations from outlets like Wirecutter.

FLIR Signature Reduction

TITAN notes that their blankets can reduce thermal signature under FLIR imaging, which is a niche but interesting feature for the tactical crowd. This is not a primary reason to buy for most users, but it is a bonus for anyone concerned about thermal detection.

Stock Availability Warning

These blankets frequently run low on stock, partly because of their strong reputation. If you see them available, it is worth grabbing a pack rather than waiting and finding them backordered.

9. S.O.L. Survive Outdoors Longer Heavy-Duty Emergency Blanket

HEAVY-DUTY PICK

Pros

  • Much thicker and more durable than standard mylar
  • 2x stronger than traditional emergency blankets
  • Generous 98x58 inch size
  • Vacuum-metalized polyethylene resists punctures
  • Machine washable

Cons

  • Heavier than ultralight alternatives
  • No grommets in corners
  • Does not breathe and can cause condensation
We earn a commission, at no additional cost to you.

The S.O.L. Heavy-Duty Emergency Blanket is the one I recommend to people who have been burned by cheap mylar in the past. Instead of thin foil, this blanket uses vacuum-metalized polyethylene that the manufacturer claims is twice as strong as traditional emergency blankets.

The difference is immediately obvious when you handle it. The material feels more like a heavy-duty trash bag with a reflective coating than a delicate foil sheet. You can pull, stretch, and fold it repeatedly without the paranoid handling that mylar demands.

At 98 by 58 inches, this is one of the largest blankets in the roundup. That extra length is enough to cover head to toe for most adults and even tuck under your feet for full-body heat retention. The green color blends into natural surroundings, which is ideal for hunters and backcountry users.

S.O.L. claims 90 percent heat reflectivity, consistent with the industry standard, and the polyethylene construction means it works as a ground tarp, an emergency shelter wall, or a gear cover. The fact that it is machine washable is a rare and welcome feature that extends its usable lifespan significantly.

Weight vs Durability Tradeoff

At about 3.2 ounces, this blanket is heavier than ultralight mylar alternatives. For car kits, base camp kits, and home preparedness, that extra fraction of an ounce is irrelevant. For ultralight backpackers counting every gram, it may give you pause.

Condensation Considerations

Like all non-breathable materials, the polyethylene traps moisture. If you wrap it tightly for an extended period, expect condensation inside. Leave a small ventilation gap or pair it with a moisture-wicking base layer for overnight use.

10. S.O.L. Survive Outdoors Longer Emergency Blanket 4-Pack

RESCUE VISIBILITY

Pros

  • High-visibility orange for emergency signaling
  • More durable than cheap mylar blankets
  • Lightweight and compact
  • Good value 4-pack
  • Waterproof and windproof

Cons

  • Reports of manufacturing location change
  • Hand wash only
  • Smaller dimensions than single-pack SOL blanket
We earn a commission, at no additional cost to you.

This orange 4-pack from S.O.L. is the best emergency blanket for survival kits when rescue visibility is your top priority. The bright orange color is one of the most visible shades to search-and-rescue teams, especially against snow, water, or dense forest backgrounds.

Like the single-pack heavy-duty version, these blankets use vacuum-metalized polyethylene rather than thin mylar foil. The material is more puncture-resistant and flexible than standard emergency blankets, and it reflects 90 percent of body heat back to the user.

Each blanket measures 56 by 84 inches, which is slightly smaller than the single-pack heavy-duty version but still adequate for full adult coverage. The 4-pack format lets you distribute blankets across multiple kits or outfit a small group.

I keep one of these in my hiking first aid kit specifically because of the orange color. In a scenario where I needed to signal a helicopter or a search party, having a high-visibility panel that also provides thermal protection is a genuine two-for-one advantage.

Single Pack vs 4-Pack Sizing

Note that the 4-pack blankets are slightly smaller than the single-pack heavy-duty S.O.L. blanket. If maximum coverage matters more than quantity, go with the single pack. If outfitting multiple kits matters more, the 4-pack is the better value.

Manufacturing Notes

Some long-term S.O.L. customers have noted a manufacturing location change in recent years. The current production quality remains strong based on recent reviews, but it is worth being aware of if you are comparing to older S.O.L. products you may have owned.

How to Choose the Best Emergency Blankets for Survival Kits

Choosing the right emergency blanket comes down to understanding the tradeoffs between material type, durability, weight, size, and special features. Below I break down the factors that actually matter when you are building or upgrading a survival kit.

Material Type: Mylar vs Polyethylene vs Wool

Mylar is the most common emergency blanket material. It is extremely lightweight, highly reflective, and very cheap to produce. The downside is that thin mylar tears easily and does not breathe, which means trapped moisture can soak your clothing. Mylar blankets like the Swiss Safe and Everlit options are best for disposable, single-emergency use.

Vacuum-metalized polyethylene, used by S.O.L., is tougher and more puncture-resistant than mylar. It is the material of choice for repeated use and for situations where the blanket will be exposed to rough ground or sharp debris. The Arcturus blanket goes further with a 3-layer construction that adds polypropylene for structural strength.

Wool is the traditional choice for reusable warmth, but it is heavy, bulky, and slow to dry. Most modern survival kits use mylar or polyethylene for those reasons. If you want wool, look at military surplus options, but plan for significantly more weight and bulk.

Thickness and Durability

Mylar thickness is measured in microns. Standard cheap emergency blankets run about 12 microns. Mid-tier options like TITAN use 17 microns. The Don't Die In The Woods HeatFlex blankets use 28 microns, which is among the thickest mylar available. As a rule of thumb, thicker mylar tears less and lasts longer, but weighs slightly more.

If you want a blanket that survives more than one use, look for either thick mylar (20+ microns) or skip mylar entirely and go with polyethylene or a layered design like the Arcturus.

Size and Coverage

Most emergency blankets are in the 52 to 60 inch width range and 82 to 98 inch length range. For full adult body coverage including the head and feet, look for blankets at least 84 inches long. The S.O.L. Heavy-Duty blanket at 98 inches is the longest in this roundup and offers the most generous coverage.

Width matters too. A 52-inch-wide blanket will wrap around most adults but leaves little extra material for tucking. A 60-inch width like the Arcturus gives you room to create a proper seal against the cold.

Weight and Packability

For bug out bags and backpacking kits, every ounce counts. Standard mylar blankets weigh between 1.5 and 3 ounces each and pack down to the size of a card deck. Heavier options like the Arcturus at 1.4 pounds are better suited for car kits, base camps, and home preparedness where weight is not a primary concern.

Signal Visibility and Color

This is an underrated factor that most guides gloss over. If you are building a survival kit for a scenario where rescue is a possibility, choose a bright orange or red blanket that doubles as a signal panel. The S.O.L. orange 4-pack and the Arcturus red version are both excellent for visibility.

Camouflage patterns, available from TITAN and Don't Die In The Woods, are the opposite choice. They make sense for hunters and tactical users who want to stay hidden, but they are the wrong pick if your emergency plan involves being found.

Condensation Management

All non-breathable emergency blankets trap moisture. If you wrap yourself tightly for more than an hour, your clothing will get damp from trapped perspiration. In extreme cold, that moisture can accelerate hypothermia once you remove the blanket. The solution is to leave a small ventilation gap, wear a moisture-wicking base layer, or pair the blanket with a breathable insulating layer like a fleece or wool sweater.

For more on managing moisture in emergency shelters, check our guide to the best bivvy bags for emergency shelter, which covers condensation issues in depth.

Budget and Value

You do not need to spend a lot to get a functional emergency blanket. Multi-packs from Swiss Safe, Primacare, QIO CHUANG, and EVERLIT all deliver reliable performance for a few dollars per blanket. The premium tier, including Arcturus, TITAN, and S.O.L. heavy-duty options, costs more but offers reusability and versatility that justifies the investment for serious kits.

My recommendation for most people is to buy a mix. Get a bulk pack of cheap mylar for distribution and disposable kits, then add one or two premium blankets for your primary bug out bag or car kit.

How Many Emergency Blankets Should You Carry?

Veterans and survival instructors often recommend carrying at least two blankets per person. One to wrap your body and one to use as a ground barrier, shelter wall, or signal panel. In a real emergency, having a backup is critical because your primary blanket may tear, blow away, or become soaked.

FAQs

Do emergency blankets really work?

Yes, emergency blankets genuinely work when used correctly. Quality mylar and polyethylene blankets reflect up to 90 percent of radiated body heat back toward the user, which can prevent hypothermia in cold conditions. The key is wrapping properly with the reflective side facing inward and sealing gaps where heat can escape. They are not a replacement for proper insulation, but they are an effective emergency layer.

What kind of blankets do EMTs use?

EMTs typically use disposable mylar foil blankets similar to the Primacare HB-10 for wrapping patients in shock or at trauma scenes. These lightweight blankets prevent heat loss rapidly and can be discarded after a single use for hygiene reasons. Some EMS teams also use heavier reusable thermal wraps for extended transports.

Is a survival bag better than an emergency blanket?

A survival bivy bag provides better full-body protection than a flat emergency blanket because it encloses you completely and seals out wind and rain. However, bivy bags are heavier, bulkier, and more expensive. Blankets offer more versatility as shelters, ground cloths, and signal panels. For a complete kit, carrying both a bivy and a flat blanket is the most effective approach.

What is the difference between gold and silver emergency blankets?

The difference is purely functional based on heat direction. Silver reflects radiant heat back toward the body, making it ideal for retaining warmth in cold conditions. Gold or olive colored surfaces absorb heat and are used on the exterior side to deflect solar radiation in hot environments. Most dual-sided emergency blankets are silver on one side and a different color on the other so you can orient them based on conditions.

Can you reuse emergency blankets?

Standard thin mylar blankets are designed for single or limited use because the material degrades with repeated folding and handling. Thicker options like Don't Die In The Woods, Arcturus, and S.O.L. heavy-duty blankets are built for multiple uses if handled carefully and stored loosely after the first deployment. Always inspect for tears before relying on a previously used blanket.

Final Thoughts on the Best Emergency Blankets for Survival Kits

The best emergency blankets for survival kits in 2026 span a wide range of materials, prices, and use cases. For most people building a first kit, the Swiss Safe 4-pack or the QIO CHUANG 4-pack delivers reliable mylar performance at a price that lets you stock multiple locations. For those who want a reusable, multi-purpose survival tool rather than a disposable sheet, the Arcturus All-Weather Blanket is my top overall pick.

If you prioritize toughness, the Don't Die In The Woods 28-micron blankets or the S.O.L. Heavy-Duty polyethylene blanket will serve you well. And for rescue visibility, the orange S.O.L. 4-pack is hard to beat. Whatever you choose, the most important step is actually putting the blanket in your kit today rather than waiting for the perfect option.

Pair your emergency blanket with complementary preparedness gear, and you will be ready for whatever comes your way.
