I’ve been wanting to try this for a while. This emergency Bivi has an inside and an outside. The inside being the shiny space blanket. In extreme cold weather, I would turn the Bivy inside out and slip my air mattress inside. The idea is to reflect the cold ground down and away with the top side, reflecting body heat up towards me in my sleeping bag. Being contained inside a space blanket bivi notoriously causes condensation, however, because there is no containment, there should be no condensation. When weather isn’t an issue, I tune it right side out with my air mattress inside. The heat reflection effect is nullified and the Bivy acts like a protective layer for my air mattress. For situations like cowboy camping, my mattress is protected. We’ll see what happens..

We always keep blankets in the trunk - now this will replace the blankets for emergency use in the winter. Lighter weight, takes less space and doesn't collect trunk debris like blankets do!

Producto tal cual a lo presentado. Espero no tener que usarla.

I opted for this bivy to keep in my emergency and first aid kit and when backpacking alone. This is easy to put into a pack as it is lightweight and has a small footprint. The sack it comes in is bright enough that it can be found easily and is made of ripstop material. However, when I opened the sack up I got a strong smell of chemicals which I personally found offensive. I am glad this is an emergency use item because I would never want to use something that smelled this strong. The material is plastic feeling and that may be why. What was apparently a whistle on the end of the drawstring fell off when I put the bivy back into its sack. Glad this is a one time use item and hope it performs when needed.

Having recently dealt with the limitations of a regular survival/space blanket (coverage to retain body heat versus block a side wind), I wanted to find a good bivy to use on my adventures. When I saw this bivy available, I wanted to try it out.Let me also say that I've spent many nights in a bivy, but those were non-survival bivies that I used with a sleeping bag and sometimes a tarp shelter as needed for wind or rain. This is not one of those and is going to be for an emergency situation. While you could use this bivy for that purpose it lacks some features and the durability of regular backpacking bivies.The bivy comes in a nice, orange, ripstop pouch with a whistle as a pull on the drawstring. While most of my packs have a whistle buckle on them, it's always good to have another. Like all space blankets, the bivy is folded way down, so it requires some effort to open to the point that you can find the open end and get inside. It's not nearly as crinkly as the blankets I've used, and it feels a little plasticky. Opening it, you can see that the bivy is made of two separate panels that are welded and taped. Depending on where I stand and how I lift it over my head, it seems to be about 6 feet and 4-5 inches long, though it has plenty of space inside to curl up in case you need to eke out a little more room to wrap it over your head. Just standing in it, I could really feel my body heat being reflected back at me. It's not insulated at all, though, so the wood floor I was standing and then later lying down on definitely sucked some heat out of me. As a continuous tube, obviously it would block wind and by positioning yourself you could get out of the elements. That said, the bottom corners are cut off, which is obviously done to allow the bag to be repacked, but it does mean that it's not waterproof. If you were in a situation where you needed to be waterproof, you could probably tape the corners or find some way to wrap them up and secure them. Speaking of repacking the bag, in a real survival situation you probably wouldn't care about having to replace an inexpensive piece of gear that had just saved you if you had to just cram it into your bag. That said, it's always nice to be able to repack and reuse gear to approximately what it had been for protection and easy transport the next time. I repacked the bivy on my wood floor, noting that when I unrolled it it was folded from the sides to the depth of the stuff sack (to create a really long piece) and then rolled or folded down to fit the sack's width. Maybe you could stuff it all into the sack, but with the lightweight material I would rather treat it gently. So, with time to think about how to repack it and an ideal surface on which to do so, I started a timer to see how long it would take for me to lay it out, fold it, and put it back into the stuff sack. It was actually quite easy, and though it took me a bit over 4 minutes. It went well, ballooned less than many tents I've repacked, and fit easily into the stuff sack.Having something to protect from the elements and retain body heat in case of an emergency isn't a bad idea. The key things I take from my review are that it is good for retaining body heat and blocking some elements, it's not waterproof due to the corner cuts (though you could try to cover them), and it's easily repackable and reusable. As soon in the picture, mine weighed 4.73 ounces in the stuff sack. Overall, I'm pleased with it, and it will be going in my gear for my next adventure.Recommended.

In your daypack, backpack, car or boat. It could save a life by preventing hypothermia. Small enough to easily fit in a coat pocket or handbag or vehicle glove box. I use mine to increase the thermal load of my 3-season sleeping bag, but I carry it with me everywhere I go here in the midwest during the bitter cold winter.

This blanket is perfect to take along when camping or to keep in your car for emergencies. You will never know when you randomly need a blanket and this one is perfect. It is well made and fits into its case perfectly. It is also very warm and reusable. I would highly recommend it to anyone.

I didn't know what a bivy sack was, and ordered this as I saw the words "emergency blanket" in the title. For those of you who don't know, a bivy sack is a weatherproof cover for your sleeping bag that you could use in lieu of a tent. Think, waterproof / weatherproof disposable cover.It is not a blanket!Now that that's out of the way, you could imagine my surprise when I received this! A tiny pouch that fit easily into the palm of my hand! And out came a thick orange plastic that unfolded over and over. It's like a heavy-duty Mylar blanket.Quality: I feel the quality pretty good. It's thick, not likely to rip, and hopefully do its' job, though personally, if it were to be used for it's purpose, I would want something thicker. Then again, I am not such a rugged outdoors adventure type of person. Read other reviews for that.Size: it's packed really well. I paid careful attention when unfolding, as I wanted to be sure to fit it back in neatly, and even with 120% attention on that as I was unpacking, I still had to pause and redo a few times. Like I said, when packed, it's nice and compact.
