Tact Bivvy® 2.0 HeatEcho® Emergency Sleeping Bag, Compact Ultra Lightweight, Waterproof, Thermal Bivy Cover, Emergency Shelter Survival Kit – w/Stuff Sack, Carabiner, Survival Whistle + ParaTinder

I'm not like the people leaving a review, when I haven't even opened or tested it..I was hesitant about this one at first, after reading some other reviews saying it was "cheap".. But I've been looking for something like this for a long time-- I've never liked sleeping bags when I'm a minimalist camper, and see no need for a giant "blanket" taking up so much space in my bag.. I'm used to sleeping on the ground so it doesn't leave me that sore.. (And I chose green because I just like it blending in more with surroundings. I don't want to be noticed when camping..)I've tried several other brands of an emergency blanket costing even more, and they were even cheaper material like the $1 mylar blankets I can buy at the local store; while online, other brands charged $20 for that same mylar blanket..But this one actually does feel like more durable material-- I can't tell what it is, but it almost feels like a "souped up" trash bag (in a good way)..I like the black lining along the sides so I can tell where the edges are, and I am short (5'2"), so I was easily able to sit criss-cross in this bag and even use the top as a hood...It's true I don't see it lasting forever necessarily, it's bound to rip sooner or later since it's still thinner material, but it's still a lot better than I expected for the price and I can see it lasting for the forseeable future. (Not like the $1 mylar blanket at the store, that ripped just opening it up..)Keep in mind, there is a difference between an emergency blanket, and a sleeping bag. This offers no padding or anything of the sorts-- just the very basics to keep you warm, which this is sufficient for. Especially for its size, I LOVE that it can fit in the palm of my hand; and unfolded it's about the size of a twin bed, but longer..As far as folding it back up, I know lots complain about that, but there's something about this material that actually made getting the air out easier than I expected..Keep in mind, main thing to remember when folding this back up, is to fold longways first. You want the only opening of the bag to be on the far side, so that when you fold/roll this one up, all the air can naturally escape from there as you fold the rest of the bag towards the opening..(And unlike a sleeping back, this was wayyy easier to roll up..! Took a little bit of "squishing" to fit back inside the holder, but it wasn't that hard. Tinier means easier to roll up, too...)Whistle works as well; and I don't regret my purchase... I LOVE having an emergency blanket I can fold back up and use again, when all the cheap ones have to be thrown away after one use; and this is so tiny that I'll be carrying it everywhere in my regular bag, and trust it enough to do its job...If they could possibly use whatever the black tape is to cover the rest of the bag, I do feel that would help with more durability so this could last forever... 😁

Ich war erstaund!Ich schlief bei ca. 8grad Aussentemperatur nur mit dem "Schlafsack" und ohne Schuhe im Wald.Also die Kälteisolation ist sehr sehr gut, nichteinmal die Füße wurden recht kalt!Der Biwaksack ist einfach gesagt ein lebensgroßer Olivgrüner Müllsack mit der innenbeschichtung einer Rettungsdecke.Leider bekam er am Waldboden einige Löcher, daher würde ich sagen das er eher als einweg biwaksack zu verwenden ist.Trozdem ist er kinderleicht wider zusammemzulegen und passt auch wider problemlos in die Tasche!Alles in allem spreche ich eine absolute Kaufempfehlung aus!

Medida idónea para saco emergencia muy recomendable

Be careful with the marketing spin on this one - this is nothing more than a space blanket fashioned into a sleeping bag. Check the other 1 star reviews...

I haven't opened it yet, its for emergencies only whenever I go out hiking. Seems good, very small and it is very lightweight, just what I need!
