#7 Arcturus Heavy Duty Survival Emergency Blanket
Award: BEST FOR CAMPING
WHY WE LIKE IT: This 60” by 82” emergency blanket has a durable Mylar/polypropylene construction with four reinforced tie-down grommets, making this a great choice as a camping tarp.
- Great as camping tarp
- Four reinforced tie-down grommets for ground cover
- Waterproof, windproof, and strong corners
- High cost
- Prone to tearing if exposed to sharp objects
- Could use four more grommet holes
This emergency blanket resists wind and water very well, using reflective Mylar on one side and two layers of polypropylene on the other side. Though it warms and helps retain 90% of body heat, it may tear if not handled properly. Given the material and size, its shape is more restrictive and is not intended as a sleeping bag or liner.
We love this emergency blankets four tie-down grommets, which have reinforced corners to prevent tearing. This makes it easy to apply ground stakes and prop up as an emergency shelter. Kudos for weighing less than a pound with its own knapsack, making it easy to lug on camping and hiking trips. If you have a bit more space available, you’ll also want the best earthquake kit.
How We Decided
In determining the best emergency blanket to buy, we explored material, size (length/weight), durability (e.g. waterproofing, thickness), design/shape, and length of warranty.
As a general rule, look for emergency blankets that are at least 47” by 70”, which can be worn by or cover average-sized adults. Some emergency blankets like the Tonyko Fiberglass Fire Blanket come in five different sizes, making it great for handling everything from small kitchen stoves to liquid and grease fire in a medium-sized room.
Material is very important. For flame retardant blankets, we recommend fiberglass fabric which can withstand extreme conditions like temperatures up to 1076°F. For emergency blankets, we are big fans of tear and weatherproof vacuum-metalized polyethylene fabric construction, followed by mylar. Both do a great job of retaining 90% of body heat, a potential lifesaver out on the trails. Alongside fiberglass and mylar blankets, there are wool blankets on the market as well. Each have their pros and cons, so hopefully you can decide which would be the best survival blanket for you in emergency situations.
Most emergency blankets also weigh less than 3 ounces, making it easy to stow away in a camping backpack. Others, like our #5 pick Swiss Safe Blankets, can double as emergency shelters and sleeping bags using included paracords, working better for the outdoors.
Best Emergency Blanket Buyer’s Guide
The Most Important Features to Consider
Our favorite fabric for emergency survival blankets is vacuum-metalized polyethylene fabric, followed by the less tear-resistant mylar. However, both have excellent body heat retention ability, keeping up to 90% of body heat. As for flame retardant blankets, we like fiberglass cloth which can withstand high temperatures up to up to 1076℉. For the best heat retention and flame retardants, no best wool survival blanket is included on our list.
- Size (Length/Weight)
Look for emergency blankets that are at least 47” by 70”, which should comfortably fit most average-sized adults. Most of the blankets on our list weigh less than three ounces, making them easy to stow in a camping backpack or drawstring knapsack. Some use their blanket as a ground cloth for cold, damp situations or under a makeshift shelter.
Design and shape is helped in large part by size. The 60” by 82” Don’t Die in the Woods Emergency Blanket can easily convert to a small sleeping tent using tape and a paracord. The Swiss Safe Emergency Blanket can also be used as a sleeping liner.
Emergency Blanket FAQs
Do emergency blankets keep you warm?
Yes, they keep you very warm using a metalized plastic sheet. For example, the #1 pick S.O.L. Survive Outdoors Longer 90 Percent Heat Reflective Emergency Blanket and the #2 pick Tonyko Fiberglass Emergency Blanket retains 90% of body heat, making it a potential lifesaver in extremely cold weather.
What is the use of an emergency blanket?
Emergency blankets are very effective at helping people minimize body heat loss that could come as a result of shock and thermal radiation. It is also very versatile and can double as a sleeping bag or shelter (provided it is large enough), as well as improvised tourniquets, mini hammocks, and as a liner for keeping food warm.
What are emergency blankets made of?
Emergency blankets are made using different materials. The most effective is vacuum-metalized polyethylene fabric, which offers a heat-reflective, tear, and weather-resistant metallic sheeting. Mylar is also another popular material that resembles a polyester film. Note, it is generally a bit less tear-resistant than vacuum-metalized polyethylene.
What other brands do you recommend?
Although not included on our list, we really like the Tact Bivvy 2.0 Emergency Sleeping Bag. It is made using tear-resistant wind, and waterproof HeatEcho reflective polyester film with extras designed for camping trips, such as an included tinder cord (for fire starting), 120 dB whistle, and a stuff sack that reminds us of the Don't Die in the Woods Emergency Blanket.
