Emergency Thermal Mylar 2 Person Sleeping Bag, 1 PK Ultra Compact

Haven't used yet and hope we never have to but I BOUGHT a whole bunch of items for earthquake or bugout kits for my 2 grown sons and their wives just to say, “I love you. Be prepared.” I hope no one ever needs to use any of the things I bought unless they want to or are going camping but we are in Los Angeles so it's better to be safe than sorry. I always read tons of reviews about everything I purchase. I am very diligent about buying the perfect item no matter if it’s tomatoes, a pillow, pens or emergency supplies or whatever. All the reviews I read on these 2-person mylar sleeping bags were very favorable. People who had already used them for camping even in snow and freezing conditions wrote that this sleeping bag kept them dry and warm. That was good enough for me. As far as protection from the elements and warmth, in the kits I also included multiple mylar blankets, a mylar 2-person tent, plus everything else I could think of (light sticks, battery or hand charge radio/flashlight dealies, first aid kit, ankle support bandages, wet-dry matches, a camp shower, little cooking stove, etc.). What I could get at dollar-type stores, I did. Saved money there. My kids have to provide their own food and water so I suggested they check Amazon because there are some excellent choices but if there is a zombie apocalypse... or worse, they are as prepared as they can be and were thrilled that I gave them all this stuff. Great, thoughtful gifts!

As you know, the point of these emergency blankets is to use them when everything else has failed. You are not at home (or the power and gas is out), you can't get to relatives, a hotel, or a Red Cross shelter... Or perhaps you are literally lost in the woods and thanking your lucky stars you threw an emergency blanket in your daypack.. The only difference here is that two people can fit, and if you have ever had to worry about hyperthermia, you know that the body heat of another is about the only way to bring up the body heat of the severely chilled person. On a trail crew as an older teen and we got one guy into a fairly serious hyperthermia situation after using a cold mountain lake to float materials for trail bridges a shorter distance than hiking them around the lake. Great idea, but several us of took too many trips. We had a sleeping bag with us in a day kit, but it lost most of its thermal capacity when it got wet from the guys soaked clothes (dumb us: take the wet clothes off first!...) One of these emergency blankets and with room for a second person would have been an easier way to get him back to normal, and taken a lot less space. From a price point of view, you can find single blankets for $5 to $20 bucks, depending on sale prices, quality and so forth. Thus, this double-sized version is priced at essentially no difference in cost and works for two. Construction is great. Four stars only because it's not a super premium version (which of course would cost more.) (EDITED to five stars, responding to a comment -- I agree.) These are designed for emergencies, so you are not buying this for multiple uses. This version seems to be at the right price point. Hope this is helpful.

Very (surprisingly) warm! We used this for a weekend camping trip. Note that it doesn't provide any padding, so if you're planning to use it for camping then it's best to have a sleeping pad. Contrary to some other reviews, we had no trouble packing it up and using it on multiple nights - it's hard to get it to fit back into its original packaging, but it fits nicely in a gallon Ziploc bag. One drawback is that the sleeping bag can be very noisy when you move around at night - like the noise of crinkling a huge piece of paper or aluminum foil. I didn't mind the noise, but other more sensitive sleepers (either in the sleeping bag or nearby) might be bothered by it. Finally, a warning against using the sleeping bag around freezing temperatures: we ended up camping in colder conditions than we had expected. Around freezing, condensation accumulates on the inside of the sleeping bag, so you will get wet and cold. Of course, the sleeping bag was not designed for such cold weather, so I don't deduct a star for this.

I'm (let's just say) "big boned" and don't really fit well in average sized sleeping bags. This is intended for two people and is more than ample for me as either a sleeping bag or a make-do tent. This alone makes this a "find" for me. In my somewhat limited experience most emergency (aka space) blankets are a reflective coating on mylar plastic. It does a great job keeping heat in but a lousy job breathing. I learned this when I let myself get over-warm in one of these and my perspiration left me damp, cold and uncomfortable. What I found works for me is to leave some room for air circulation. I don't wrap myself too tight. Better to be a little cool or cold and not sweat and have a bit of circulation to help keep me more dry. While this is reusable I seem to be incapable of re-folding these to anything near the folded size out of the package. Having this XL sleeping bag in my car is a comfort in case of getting stuck in a snow storm or just frigid cold (like we had in around New Years for several weeks here in New England). I'm not really a camping person, but as a tool for an emergency I'm very satisfied and hope I never need to use it! For a sense of peace of mind I'm giving this 2 person emergency mylar sleeping bag 5 stars.

I have used this as a blanket on below freezing nights. It worked well. My bulldog loved it too. Im thinking of buying more for window insulation+

This sleeping bag did work well for wind protection/heat retention, but was made of an extremely thin and flimsy material. It was windy outside when we used the bag, which caused it to inflate like a humongous trash bag as soon as we unfolded it. It was difficult to get inside, and then situate ourselves, and the material is so thin that the bag acquired a tear along the side by the time we were both inside. We situated the rip underneath ourselves and were surprised at how well it worked for blocking the wind and keeping in heat. But when one of us got out to use the bathroom, the bag ripped in two more places, and about 4 hours after opening it was shredded beyond use. 2 people in -> 1 out and back in -> 1 out = shredded. It was particularly windy, but we were trying to be careful. This would be great in an emergency when it isn't abnormally windy, just be very careful, and don't expect to get multiple uses because it is incredibly delicate. Bonus: the outside is super reflective shiny, but you can see through it from inside!

I BOUGHT THESE FOR THE SAME REASON I BOUGHT THE ONE PERSON SLEEPING BAG. WHILE HIKING THIS MIGHT HELP A COUPLE SURVIVE. IT ALSO CAN BE USED FOR OTHER REASONS LIKE IF YOUR CAR BRAKES DOWN. HOLD UP TO 95% OF YOUR BODY HEAT INSIDE OF BAG. IF YOUR HURT OR LOST OR JUST WANT TO GO CAMPING. AND YOU WON`T HAVE TO CARRY A HEAVY SLEEPING BAG. PLUS YOU CAN BRING MORE FOOD WITHOUT THE SPACE THAT A REGULAR BAG TAKES UP. AND ALSO GREAT TO CARRY IN YOUR CAR JUST IN CASE.IT`S ABOUT THE SIZE OF A BOOK WHILE FOLDED

I bought this in order to supplement our 45 degree mummy bags on higher elevation and colder trips. Based on other reviews, I was worried about how reusable it would be. I bought two things to suppement my project: 1) 10ft self adhesive Velcro 2) roll of gorilla tape I cut a slit down the center, full length and lined the cut with gorilla tape on every edge. I also reinforced the original seams I placed the Velcro over the tape along the center and voilà we had a double weatherproof bivy for our sleeping bags - we placed out mats inside as well so it wouldn't be as loud and would help with more internal insulation - we zipped our mummy bags together I added some rope to the end so we could fold it in to quarters and roll it up as well The only drawback I that we ended up with a little condensation on one side each morning after sealing it up about 50% of the way each night when it dipped in to low 50/high 40s
