    Emergency Sleeping Bag With Hood | Ultralight, Waterproof, Thermal Mylar Sleeping Bag LinerPretty much a single use survival tool for emergency use situation, but will function as intended. Price was high at $17.95 so I will shop around for better pricing next time. This item’s advantage is that it’s form is a bag rather than a blanket and that there is slightly more material at the bag opening for the user to form a hood- in a dire situation these advantages would be useful. Material is Mylar with foil type surface, very thin, does not function well alone -without normal sleeping bag or blanket- but is meant to be used in conjunction with sleeping bag/blanket (or at least warm clothing) to retain some heat so that the cold doesn’t kill you. If the user is careful, and doesn’t tear/puncture or pop the seams, it can be very useful to keep you dry in a wet environment, certainly important in survival situation. Being that this product is basically a plastic bag, it is not designed to breath at all, if you use in a warm climate, expect it to trap moisture from your body and sweat inside the bag. It is small & light weight so it can be carried in a pack to aid survival if needed, but don’t ever expect to roll it back up in it’s original, compact size baggie, just use it if you need to and expect you will need to take care to not rip it during it’s usage. then probably toss it out and get another.

    pretty good comparatively speakingI found this to be one of the better emergency bags out of the bunch, it feels a little thicker(subjectively)than some, and plan to keep it in m gear just in case.If there is ONE criticism, it’s that the teeny tiny sack provided is just too danged small! Try to put it back in, IN MY HOUSE, proved to be a 15 minute ordeal. I suggest making the nylon/plastic drawstring bag just a big bigger, it will make it far easier to use. Out in the field, it wouldn’t be practical for anyone, after all COME ON! these things are folded by a machine to fit the sack at the factory.I’m keeping it, but will dig up some other case for it, as I DO like it.Oh, yeah, they send it out in this great little cardboard carton, the best packaging I have seen for such things.

    Once You Open & Use-You’re done! NOT Reusable (Per Manufacturer)Been using these as “disposable” emergency blankets. (I kept 10 in my cruiser’s trunk at all times.) Now, they have improved the seams & durability in the almost 8 years the department has used them. But, they are still listed as non-reusable.Once you take them out of the pouch, you will NEVER get it back in the pouch.=just be aware of that fact.I recently bought more to put in our private cars, as I’m not RETIRED & living 1.300 miles North of Florida. It get’s a little cold up here in the winter, but After 30+ years down South…I still miss the seasons, The deer I hunt & eat are bigger than German Sheppard’s (unlike Florida.)VERY well priced. Buy a few, keep in your car. Then when you need it-you’ll have it.FYI-I am a tried & trued user of this product. It gives you the most “bang for your buck.” My Sheriff’s department would haven’t of bought them-if they were NOT cost effective.

    WarmThis sleeping bag did exactly what it was designed to do. It kept me very warm. A side note though is to keep in mind that this is similar to an emergency blanket and it doesnt breathe so there is a high chance you will wake up in a pool of sweat. It isnt a bad thing, it means its working correctly.

    Product spoke for itself.Must have on any outdoor hike.1) Safety tip of the day. If you don’t have a compass and you end up in a swamp don’t move if it’s a cloudy day. Remember Sun rises in the East and sets in the West.

    Great for survival kitsI haven’t actually used this bag because I bought them for our survival kits that I keep in our storage, but the quality and compactness of this item was very impressive. I noticed that this company also has blankets and tents. I plan to get some of those to add to my survival kits as well. I was very pleased with this purchase.

    Good for an emergency, not regular use!Bag was lightweight but extremely long. I used as a liner in my sleeping bag for a fall camping trip. Definitely kept me warm but not only did it hold body heat in, it also created moisture in the bag. I woke up with all my clothes damp and the liner “sweating”. Product works but I would keep it to emergency use . . . and have dry clothes available.
