Not very fuzzy,
This product is probably what you think it is. One of those loud, crinkly, reflective “space” type blankets. They’re fairly cheap, and you get a lot of them. They’re very useful for keeping a person warm if you know how to use them.
Some people complain that it doesn’t keep them warm at all. This is most likely because they aren’t using it properly. There are better articles for this information than this review, but essentially.. This blanket prevents heat-loss from radiation (which is how the majority of our body heat is lost). Radiation is when heat radiates away from its source. This is where the product shines: it allows hot pockets of air to form between you and the blanket. It doesn’t do much to protect against conduction since it’s so thin. Conduction occurs when heat transfers from one place to another by touching. When you grab an ice-cube, you are losing heat because of conduction. Similarly, if you are in a very windy area, while the blanket itself is wind-proof, the cold air can get under and inside the blanket, stealing away your warmth.
As such, when using this blanket, you should squat down and wrap it around you. By laying on the bare ground, there is no “dead air space” for the hot air to collect so, by the process of conduction, your body looses heat through the ground. This product works really well as a sort of “base layer” type of blanket. If you have a sleeping pad and sleeping bag, line the insides of your sleeping bag with one of these and you’ll be toasty in no time. Just be sure not to start sweating too much, because of hypothermia and stuff. Even without those fancy sleeping bags, one of these covered by a wool blanket will keep you very warm. Just remember not to wrap the blanket to tightly around you. It is instinctive when you want to get warm, but it’ll decrease the effectiveness and may rip it since it’s so frail.
Five stars because it does what it is intended to do. And while it’s quality isn’t super, and it isn’t made out of top-notch ballistic nylon, it isn’t being marketed as if it were. It is intended to be a cheap, disposable cover to be used in emergencies, and it does that job wonderfully.

|I had my doubts…but not anymore,
I purchased this product (Emergency Mylar Thermal Blanket pack of 10) to put some in my wife’s car, my car, and an emergency kit. I have never used one of these before and I thought that they would just be an “okay if I have to” use. Boy was I wrong! I took one out at night (45 degrees F) to test it. It kept me delightfully warm, not hot, but a comfortable warm. I did not feel like I was wrapped in plastic wrap which I thought I would feel. I also tried to push my feet through it (holding on with my hands and with two feet pushing as hard as I could) and all it did was stretch a little but nothing serious. However once it is punched (with a knife on purpose on my part), it will continue ripping fairly easily. Over all this is an excellent, very light weight, cheap price to not freeze in a crumby situation.
FYI The blankets I received are made by B-H Supplies, a 52″ by 84″ (not 54″ by 82″ if it matters) and holds in 90% of body heat. Also it sounds like tin foil when you are moving around. My father added that in his survival training they said use two, one for the floor so your body heat does not escape into the ground and one around you while covering your head for maximum warmth.

|Great price!,
I purchased these to make emergency kits for my families cars. They are not expensive and could save their life if they break down.
My brother used a few to line a dog house he made. He turned them so the heat from his dog would stay in the dog house. My mom used one as a sun shade in a garage window. She turned them around so the heat would reflect back out the window. You can still see outside but people can not see in. Great little gifts for people and have many uses.
edit:
A warning (in response to a post I received). Please make sure there is nothing between the blanket and the glass of the window if you are going to use them as a sunshade and/or for privacy. These little guys reflect a lot of heat and anything between them and the glass could be damaged.
