I always keep 3 trash bags in my kit. One, to step into and pull up. The larger muscles in your legs generate quite a bit of heat. Another one I make arm holes in and pull over like a poncho, keeps the trunk warm and dry. The third, split down the side, open up and put over your head. This configuration will shed water. Use duct tape to hold it together.
I have a mylar bag for the legs and blanket for the body. Get in the bag with your legs and then wrap the blanket around your upper body. Ihad to use a zpace blanket once years ago. Not that kind but the thicker reusable one's. It made a bad situation bearable and I am hede to talk about it so I have a first hand experience they do work. Thanks for sharing.
Mylar E blankets will help you conserve some body heat, but you have to utilize them in ways that maximize their potential. Wearing one inside your jacket will offer much more heat retainment than simply using it over your clothing. When worn over your outer clothing in frigid temperatures, most heat will be lost through convection. This is the cold air coming into contact with the material. If you were to place the mylar sheet on the ground in order to lie on it, it will not reflect much heat at all back to your body due to conduction..when the sheet comes into contact with the cold ground, the ground will cool the sheet and suck the heat away from your body. You'd first have to place bedding between the ground and the sheet and then another layer of bedding on top of the sheet. These E blankets will help quite a bit if utilized correctly. Also remember that you can lose up to 70% of your body heat through your head. Always wear a watch cap or other head gear to help prevent heat loss. You can place strips of an E blanket inside your pants legs, just wrap it around each leg inside. Same goes for feet. I've done this in the mountains at near freezing temperature's without a sleeping bag and it worked fairly well.
I agree with everything you said except the 70% heat loss through head. Apparently that's been way over exaggerated for years and it's more like 7 to 10%. A myth made by the hat companies! Lol. 👍👍
Interesting. I was about to give up on this thing when I used it as a sleeping bag the other day down to 5 degree Celsius. I felt no temperature difference. I'll try to keep it closer to my body next time.
Do some more investigation into the idea that you lose 70% of your body heat from your head. I'm pretty sure that's not true and it's not useful information that will help you survive in unexpected conditions. I am interested if the rest of your information is accurate or helpful.
Wearing the E blanket next to your skin and not as the outermost layer in frigid conditions could be a death sentence. When worn as an inner layer, the blanket will trap the body's moisture, which will condense and make you completely wet, and then freeze you.
You should always put those over waterproof outerwear because when you have that around you you’re going to sweat like nobody’s business and I could give you hyperthermia fast. Also if your outdoor camping in the winter always put it over your sleeping bag not inside with you. You should always put it over something waterproof.
Last winter I hammock camped with a buddy. Temps in teens. He tried to use one of these between his body & hammock instead of a pad or underquilt. He was MISERABLE! He tossed & turned all night. The constant crinkling of that damn blanket kept me awake all night. Because my buddies & I are kind of jerks to each other, I found it hilarious 😂. It did help me realize I needed to learn exactly how these are designed to be used before I find myself in a survival situation.
these are in my opinion great for adding to a shelter I have a small two person tent and I will normally tape one of these to the inside of the roof so to speak and it is a helpful thing when it gets colder.
They work. I played “ victim” in a Wilderness Medical Class. I was wrapped-up in 1 and laid down in the ice and snow for a good while... was comfortable considering...so yes, these should be in every kit.
@@slackerengi2401 If you lie on it, it doesn't work apparently, as he said his bare skin touching the blanket he did feel cold because of the conducted heat through the blanket, work better as a tent your right, I think I will get some. *PS: Suffocation* probably why they don't make a space blanket big enough you can completely wrap up in!
Ty for sharing :D > Yeah bigger and more than one :D Tip. Jumbo paper clips/clothes clips help give options for hands free, a way to seal it up and gives a better chance to fold it up. Duct tape would also go great (credit card size) to make reinforced corners and fits the packaging. Putting the mylar over a t-shirt but under a jacket makes a vapor barrier and gives the mylar more structure/sable. Mylar still conducts heat on its surface so just a little bit a way from the skin to get most benefit. Straight branches can be hammered into snow /ground. Lash/tape on the mylar and face it into the wind while trying to make it still have some tension. Sticks/snow/sand/rocks can be used to hold the mylar down. Mylar can do so much. It just needs structure and a shape to take up.
This is EXACLY the type of video I wanted to see for a review. Sub freezing temps complete with gauge 45F versus 32F I guess if you can keep your vital organs warm you will survive Thank you so much!
The two times I have had to use one of these blankets, bivouacked up on a alpine climb, they were all ripped by the morning. But they did help a bit, I put it mostly over my head a face and keep the wind off.
In really cold temperatures use your coat over top of the blanket. If well protected people can stay in negative degrees for hours and hours. I know I've done it....
I've done that with them in place of using newspapers while out riding a motorcycle and it got too cold. To be fair, I've never seen them advertised as "Snugly Comfsy Cozy" but, for a buck, you won't freeze.
They actually are comfy, i was cold drunk and shirtless on the beach one night at like 4 AM i rememberd i had one in my swimming trunk pockets and i passed out on the beach i got so warm and comfy
I sometimes drape mine over my sleeping bag if the night is colder than I was expecting. The heat radiates back immediately and I'm comfortable for the rest of the night.
Get the extra large and a tarp that is similar size. Spray contact cement on the tarp and lay Mylar on it. The tarp will make it really easy to deal with wind and help strengthen the Mylar. Use holes to use it as a windbreak if you have a fire.
Don't wait until you're cold. Make a mylar shelter or add as insulation well BEFORE you're cold, because the only thing it does is help you keep your body heat. Also, don't take your jacket off! Keep the warmth.
Thank you for testing this out in the cold weather without your jacket on so we don’t have to. A person could wrap one around their waist and one around their upper body.
Thank you for this.I have never even open one and like you have carried these for years in my snowmobile suit pockets along with a a fire starter, and one of those little cable saws. I carry these in case I go,through the ice. I carry more substantial things on the sled itself.
I make heat reflective clothing, breathable, wind and waterresistant/proof. My Anorak and overpants weigh a mere combined weight of 6.34 oz. They provide full coverage except for my hands which my heat reflective mittens cover for heavy wind, rain and snow. In 36 deg. F temp., I stayed comfortable hiking. I overheated while moving too fast. It took 10 min. to cool down as I moved slower. My point is that when used as a blanket, cold air and wind still affect the efficiency of the blanket. You need Tyvek 14-M. I purchase mine from Quest Outfitters. If capable of measuring, cutting and bonding material based on your best fitting clothing then you might consider making your own with the heat reflective Tyvek.
So here is a DIY for you if you take a blue tarp and stick the two together with adhesive spray or super Glu you will get a thicker blanket that you can fold up and put in your bug out bag. It will feel more like a blanket and keep you warmer. Wind is your enemy so I do recommend if you use the blanket as it is or the way I told you about make sure you construct a shelter. A simple triangular tint shape would do. You can notch the sticks at the ends(one male end and female end which would look like a gap in the center)so they fit together and then tie them with a rope for better support on the tent. I found the wood stays together better then just tying the two ends together crossed. If your buy a Christmas type tree you can use the branches to cover the structure quick. this will keep the tarp from blowing off you at night.
One of the most versatile survival implements to have on *any* outing is a generic blue tarp. I tour North America by motorcycle camping for free where every I can set up a tent. Tarps offer weather protection, rain water collection, and somewhat effective wind blocking if deployed correctly. I never hike, travel , or venture far without one. A fire starter, knife, paracord, and a tarp; Everything else is just for convenience! ;-)
It occurs to me that even the cheapest, plastic, rain poncho over the mylar would be a significant improvement. The foil would be better held in place around you and the combination might provide some convective insulation as well as radiant insulation. Your thoughts/suggestions?
The best thing you can do with them is to use an iron and weld three of them together. give the edges about a 3 inch overlap. With three of them put together you will have more than enough to cover up with and still have some of it to use as a ground cloth to fight the ground from stealing your warmth.
Here in canada, the dollar store sells those blankets as well as sleeping bags and small pup tent versions 1,2 and 3dollars ,I bought the sleeping bag one as reflective material in grow room, it was at least two of those blankets
From 30 to 47 can maybe allow for a nap, maybe, depending. Definitely could save a life. I'll add 2 to my go-bag. Thank you. Nice to have a "measured" approach to what would otherwise would be a subjective assessment.
@@NaeMuckle mate, not going to work, thinking how humid i was, i would have needed probably 50 taped all over me ! It sounds good on paper but it's fairly impractical ! The silver blanket was literally dripping and i was freezing ! Coldest nights so far in my life ...best thing ,carry a heavier duty sleeping bag and God willing you are sorted ! Enjoy the outdoors, take care, God bless !
@@Poop-nu1so i was far from home, wanted to spend a bit more time where i camped and it was pretty much an emergency, having nothing else to cover myself with and not wanting to freeze to death !
great test . in a bad situation it could save your life hence the survival blanket name lol . dont think it is a choice blanket for sleeping with but hey in worse case . how ever they work great for heat reflectors and shelter builds if needed . they also work great for keeping food cold as well if you hike out in the woods with meat couple frozen water bottles wrapped up in a bag with your meat or hey even beer lol and it will stay cold for hours . food for thought .god bless happy new year brother .
Thanks my friend. That's a great idea, a good way to keep the beer cold. always looking for a way to do that. And food too. Happy new year to you to my friend and thanks for watching and your comment.
Nice test. Although after watching this video, I think I would pack two of these. One for a ground sheet, and one to cover up with. Maybe some duck tape to put them together. But as Calvin pointed out, they do make sleeping bags and tents out of this. I now keep two of the sleeping bags in my Jeep, one for my wife and one for me. And the sleeping bags aren't that much bigger either. I have never tried the mylar blanket, they were called Space Blankets when I bought mine..lol This is good info though, thanks, I always wondered, now I don't have too. Simple but effective
These require some dead air space between you and the space blanket to work at their best. If you use them to line a shelter, or as a makeshift tent over you, thats where they really shine.
This is the third emergency mylar product I've seen you review I saw the tent and sleeping bag too I love it Table top reviews and commercials are no replacement for in the field review Keep up the great work, I subscribed
tape several together into a bag, you can make it as bag as you want with that ten pack you mentioned. then fold out into ziploc bag a d squeeze the air out.
THANK YOU SO MUCH FOR DOING THIS! I learned A LOT ABOUT THE BLANKET'S, I ALWAYS WANTED TO KNOW! 10° Heat Up! An to get the FULL SIZE FOR MY BODY! THANKS AGAIN, JESUS BLESS YOUR DAY.
I agree it is better than nothing but I believe there are better products out there that may weigh more and take up more a bit more space but be far more valuable and reusable. Jason
primalarcher Hey Jason, One is just not enough! Its a little to small if you had two it would be better (maybe).. I think there are bigger ones I hope! It would still be a long night if you had to use one!!! But its better then nothing! Thanks take care!
Thanks for shivering for the rest of us. I just think that one is not enough. I carry two of them in my day pack. One to lay down on, and one to go over you. They are noisy, they don't breathe at all, etc. So you are going to have a crappy night - but that isn't the point. Make a bed out of leaves or green branches to get more insulation between you and the ground, ideally in a sheltered area and out of the wind. In winter, you should have a mylar bivvy sack and just suck up the extra weight and cost.
trustbuster23 Thanks for watching! And for your comment! Your right you must have two of them to make them work right! I did buy a bivvy and it works real nice! Thanks again!..
How many times can you reuse? I also believe if you don't have a normal good sleeping bag and you insert the foil inside the sleeping bag it will increase the heat.. What do u believe?
There is N0 insulative value in that thing ! Its a wind and moisture barrier, they totally work by reflecting "Radiant" energy produded BY your body 180° back to the source. It is impossible for a radiant barrier to "trap" heat unless you are 100% enclosed and air. Tight. The shiny surfaces are actually 2 films of Aluminum over a polymer base layer. Aluminum is actually an excellent conductor of heat and is capab.e of conducting body heat away from you, which is why it feels cold when touching your bare skin. They're thin , tear quicker than a twenty-five cent prophylactic and you'll never fold that thing back to its original size . In the Desert they'll make shade, reflect the sun and "possibly" help limit sun & wind burn.
hmm. It seems to me worn like that it's just a windbreaker. Did you by chance test it under your coat to keep your body temperature in? I tested heavy duty aluminum foil on one foot and nothing on the other foot. On one I put socks, aluminim, then a plastic bag to keep it from tearing, then a sock over that. The other just 2 socks. The difference was amazing. One foot was still in my house, the other outside freezing. . lol. I should have put sock, plastic bag, foil, plastic bag, sock because I forgot and did laundry. It took awhile to get the disintegrated foil out of my sock after the laundry.
one would think that it would be better to rap the space blanket around your waste then put back on your jacket and use the space blanket as a jacket liner it might be quieter with the jacket on as well
A lot of these *Mylar* blankets are way too thin. Dont get me wrong they work BUT if you *layer it up with a stronger yet pliable material like Tyvek* or some other brand of house wrap then these things would be WAY more durable.
Beware of moisture retention. The reason I suggested Tyvek (house wrap) is because it can breathe while letting heat/condensation out and keep rain and/or humidity from getting in. Also Tyvek doesn't soak up anything like a bed sheet would. Either way, good luck. Eidited: I should mention that I used the Mylar in a "pettern" type configuration (almost grid like) under the Tyvek. The reason for this is because the Mylar itself does not breathe.
Thanks for the great review!! They should make a body suit out of them, or at least a poncho type. It would be easier to wrap a poncho shape one around you.
Niestety większość RU-vidrów używa koca niewłaściwe.To nie jest przypadek że koc ma dwa różne kolory.strona srebrna odbija podczerwień , natomiast złota pochłania i rozprasza promieniowanie IR. Więc jeśli chcemy poprawić ciepłotę ciała to używamy srebrnej strony w kierunku ciała.
Thanks for doing the test, but I would never carry one for a survival situation. You will get wet, the wind will get in and get you hyperthermic. I carry a 3 mill orange 55 gal drum liner and a square piece of reflextix to sit on. Cut a V shaped hole for your face near the bottom seam and you'll stay dry, and warm. The orange color will get you found even if you fall asleep
those things are soo noisy to sleep in, crinkleing and rattleling and def not comfortable. You wont be snuggleing up or cozy. Mine, I folded it as tight as possible and put it in a small nylon bag with a pull string. It will get even smaller shoving it in a bag smaller than the size you can get it down to by hand. Windy? Wind can send this flying off like a feather in the wind, just with a lot of noise. There is also an emergengy tent so you can have that and the blanket and hope everything doesnt blow away an you have a noisey night trying to sleep. Raining? Any shelter is better than no shelter. You bought 12? I wonder if its really cold if you can use more than jusr one, even lay on a few then cover with several. Even in an emergency mylat pup tent.
What would really help is using a fire with a shelter. The Mylar will take that heat and apply it to you. In most survival situations one would seek to: 1) Get out of the wind 2) Build a shelter 3) Build a fire When all three of these are combined the results are awesome
Cheap flimsy blanket that becomes worthless in the wind. If you can't keep it on what good is it. The better made ones with double layer don't reflect as well , but will keep you covered. Both will sweat from condensation, so clothing with a vapor barrier will keep you warmer when wrapped up in a survival situation.
32 degrees c is a hot summer's day! who on earth uses Fahrenheit these days? C makes a lot more sense. 32 degs F = 0 degs C so basically freezing point of water 45 degs F is 7.5 degs Celcius, so that isn't very warm at all.
