I’m already feeling the extreme appreciation of having one of these in an emergency situation where supplies are limited or non-existent. And I can already hear the noisy and crinkly experience it will be giving me while sitting in that appreciation. Super thin and lightweight Mylar that’ll help keep me dry and warm enough in the rain, wind, and snow to likely tell the tale afterwards. And is plenty big to wrap me up fully with some to spare. Fits nicely in its little orange sack and comes in a 5-pack for keeping a few in the car, backpack, camp, or cabin. It’s one of those items that needs to be put in place prior to actually needing it… highly encourage and recommend.
Dear John, Verified Buyer –
I own other brands of these and these seem just like those. I keep them in hiking backpacks, my glove box, and go bags. Handy for emergencies.

Extremely light weight, perfect for an emergency or for hiking/camping trip. Madd of the same material as mylar emergency blankets. Great find!

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.

These are really good quality emergency sleeping bags. I got them to add to the kits I’m putting together for houseless people in the area, and I’m really happy with how durable and well-made they seem. They’re lightweight, easy to pack, and should offer solid protection and warmth when it’s needed most. Definitely a good addition to any survival or support kit.
