Emergency Sleeping Bag Survival Bivy Sack Use as Emergency Blanket Lightweight Survival Gear for Outdoor Hiking Camping Keep Warm After Earthquakes, Hurricanes and Other disasters

This sleeping bag generates serious heat and keeps it in too! Along with that comes the moisture bodies naturally produce, so be prepared as you may wake up with a think layer of moisture on the entire inside of the bag. It did the trick in a pinch and is an excellent emergency preparedness item.

I keep these in my car in case of emergency and in my backpack when I go hiking. I love they are compact. Have not used yet.

As advertised and serves it purpose as an emergency bivy.

This little bag kept me warm in around 20 degrees Fahrenheit temperatures. Make sure you remove your shoes and socks when sleeping because your body heat will be what warms you up. Sweat will collect in the bag, especially if temperatures start to increase while you sleep. Since it's plastic, don't expect to be able to launder. You can rinse it and hang dry, though. Durable and very good value for the price, especially since there are two bags.

So small and compact. I keep one in my car and in my concert bag for outdoor concerts when summer eves might get chilly. Perfect

Good addition to a bug-out bag.

These are actually really nice. I don’t know about how well they keep you warm, but opening one up it’s not bad. I was expecting something really cheap and this isn’t. It’s one of those glad you have it, but hope you never need it things.

A much better emergency bivvy bag than the thin mylar emergency blankets. This one is heavier duty, and it's easy to roll back up for re-use. Great for an EDC, BugOut or to keep in your vehicle in case of stranding.
