Preparedness achieved, emergency pending.
I purchased these foil emergency blankets for reasons that were, at the time, impeccable—though accessible only to my sleeping mind. In the first dream, I knew with absolute certainty that I required them. The situation was urgent yet undefined, the sort of emergency that demands preparedness without ever troubling itself to explain why. The blankets shimmered with purpose. I felt reassured. In the second dream—deeper, clearer—I was already using them. I was warm. I was safe. I was nobly wrapped in reflective dignity, protected from the elements and from regret. The blankets performed flawlessly, exactly as one hopes emergency equipment will, even when the emergency itself remains symbolic. Then I awoke. Upon inspection, the world was calm. No exposure, no crisis, no immediate need for thermal intervention. The blankets remained folded, pristine, and faintly judgmental. I realized then that while I may someday require one foil emergency blanket, I almost certainly do not require four. And yet, I do not resent them. They sit quietly, prepared for futures both real and imagined. The material is lightweight, neatly packaged, and convincingly reflective—capable, I am sure, of saving a life or at least dramatically underscoring one’s seriousness in a mild inconvenience. They have done nothing wrong. They simply arrived ahead of their moment. ★★★★☆ — Excellent in dreams, impeccable in theory, and patiently waiting for an emergency worthy of them. Until we eat again, Percival Toadwell Van Bristow

Must have in your kits
I have these in all my First Aid kits, and they come in a nice compact size perfect to be tucked away and not taking up too much space in your bags. Once they are unfolded, they are pretty big to cover an average size adult, but a second one may be needed for a very tall person so carrying two in your kit is best. They definitely hold in the body's heat, good quality and does not tear easily making it perfect to use not only as a blanket but also to wrap over the shoulders if needed.

Functional and affordable
I bought these to line boxes to leave for feral cats during freezes. They worked great for that. It's basically just mylar and very lightweight so I was able to just tape it along the inside of the box and then fill it with straw on a self-warming pad and all of the cats successfully made it through sub freezing temperatures. We will keep some of them on hand to have an emergency but I'm very happy with it. It is very lightweight and wouldn't hold up to a heavy wind if you had it wrapped around you but great to have it a pinch and certainly worked for why I needed it.

Great addition to your car's emergency kit.
I started a emergency kit for my car this year. I need to emergency blankets for one of my first purchases because I live near the mountains and they could be useful if caught in the snow. I haven't tried them yet, but I've been told that they are very durable and the heat level keeps you warm and dry. It would be good for anybody who travels.

Great space blankets
Homelessness is everywhere, especially so in Albuquerque. I bought these and hand them out along with sandwiches at the camps. These blankets mean a lot to the homeless because they are so efficient, compact, and affordable.
