I am a firm believer in the effectiveness and warmth provided by these reflective mylar emergency bags. THEY WORK! In an emergency, these will keep you from going hypothermic. They are a vast improvement over the thin, small "blankets" you've probably seen or been advertised. This material is much thicker, is an actual enclosed bag and has reinforced seams for long term use. I regularly go on backpacking trips into remote areas and should temperatures drop unexpectedly, I keep a couple of these handy, one myself to stuff inside my sleeping bag for a substantial boost of warmth and another for rendering aid in an emergency. They are easy to roll up and return to their small carry bags about the size of a pop can and weigh a few ounces. I highly recommend these for everyone to keep for emergencies. One for every family member. I made first aid, stranded traveler emergency ration kits for all my young adult children and along with those items, they each have 2 of these bags packed in their vehicles. We live in the upper midwest where blizzard conditions while traveling can overwhelm drivers and can, and have, led to tragic outcomes. So we travel prepared. I highly recommend this product in particular some extensive use in sub zero conditions. You can buy those $1.99 "Space" blankets if you want, but I wouldn't bet my life on them.

This looks like a better addition to my emergency kit that I take on every hiking trip. The kit currently includes a mylar blanket that absolutely is not reusable, but isn't quite as heavy as I remembered.Yes, things like this are good to have! I have deployed two emergency mylar blankets in the past. They were not life threatening situations, but sometimes it is worth the cost of replacement to go ahead and use the thing. Even better if it is reusable and there won't be a cost of replacement. The first came out when I decided I needed a roof more than a floor to go with my bivy. The ground cover (and some emergency cord) became my roof and the emergency blanket became my floor. It worked okay for a week of rainy nights. The second time was when I was expecting dry and maybe freezing temperatures and got 24F and a bunch of snow on not one, but two nights out of four. I pulled the emergency blanket over the top and it held up to the two nights. It is arguable that that didn't become life threatening because I was willing to deploy the blanket. Fortunately there was no wind and it stayed in place with a few little rocks, but a bag like this product would have been better in that situation.Deploying those other blankets is difficult, it must be said, especially after knocking about in the pack for a couple years. It took great care to get them unrolled without tearing. The layers were sticking together and I just had to settle in and take the time to do it. Part of the problem is just that they are so very brittle. As it comes out of the packaging, this one is a lot easier to open up so you can open it quickly when minutes count. What it will be like after riding around in a pack for 2000 miles remains to be seen.Is this reusable? It is certainly tougher, which counts even on a single use. It is wind and water proof, but only if there aren't holes developing! Holes and tears cause problems and you will have some with the lighter blankets. However, I doubt this will be in good shape to trust for a second emergency after getting used the first time. It will stay around you since it is a bag, not just a blanket, and that counts for something too. If a blanket is needed, it can be converted by cutting. You have more confidence and more options with this product.There is a weight penalty for this better emergency solution. I get 137g (4.8oz) with the storage bag, more than the 4.2oz claimed in one spot or 4.6oz in another more visible spot. My scale reliably measures nickels as 5g each, so I'm confident of the accuracy. Removing the storage bag only saves 8g and leaves the emergency bag vulnerable. The current emergency blanket is only 54g (1.9oz), but it does have drawbacks. There are definitely a few hikes where I'd rather have the heavier one.

This is honestly an item that I would recommend to anybody/everybody and would honestly suggest that everyone has at least one on hand for each member of their family, hunting party, fellow adventurers, etc. If not have several of them stashed away for emergencies in the trunk of your car, the closet/cabinet of a vaction spot, and above all else in your backpack if you're going in an outdoor adventure of any kind because these things are literally a life-saver in a number of emergencies in which staying warm is a major concern.These blankets are constructed from Mylar, a synthetic material with interwoven aluminum fibers which reflects and seals in body heat, thus enabling any warm-blooded organism to keep warm even under the most extreme conditions, including outer space. Yes, these are often colloquially referred to as "space blankets" due to their history of being developed by NASA for Astronauts onboard space shuttles.They're practically a necessity for any survival kit, but frankly I would go as far as to say they are something that everyone should have for emergencies in general. They're also commonly referred to by EMTs as "shock blankets" due to their utility for keeping someone in shock warm. But frankly, they're are a large number of scenarios in which these are good to have. For instance, say your car breaks down in the dead of winter during a snowstorm, if you've got a few of these in your trunk, you're covered.They've super lightweight, extremely compact, easy to carry along or keep stored without taking up much space inside of a pack, and they're inexpensive.
