Ultralight Mylar Emergency Sleeping Bag for Survival and Hiking 5 Pack

This review is for the Sierra Madre Emergency Sleeping Bag – Ultralight, Waterproof Mylar Thermal Bivvy Sack Tent for Hiking, Bug-Out Bags, Survival Kits – Emergency Survival Space Blanket for Heat Retention 5 Pack You won’t mistake these for a regular sleeping bag replacement, but that’s not their point! I got the 5 pack, fully expecting to sacrifice one to testing and put two of each in my wife’s car and my truck’s emergency kits. Turns out that I am adding that fifth back into my truck kit since after (some swearing and) much patience,. I got it folded and back into it’s pouch. At 7′, it’s long enough that at 6′ tall, I can sleep on my side with slightly bent knees and get the top up over my head. It’s tough enough feeling that for a few nights, this can help keep you alive. It *might* make for a decent outer shell for a 3-season bag, but I have doubts about its long-term durability. For the night/few nights it was intended for in an emergency, this is a solid choice.
