It's meant for EMERGENCIES not regular use.
I think most people reviewing this are missing the point. This is not meant to be an item that you reuse multiple times. This is meant to be in a life-or-death emergency situation, it will keep you warm until you can find help, type of thing. And for its intended purpose, it's perfect. Its lightweight, easy to pack in the car, and easy to use to warm yourself up in an emergency situation. Yes, the string comes out of the whistle part easily so that you can use both the string and the whistle in an emergency. It is very simple to just string the whistle through the paracord and slide on the cord lock to hold it in place. I really worry about everyone out there in an actual emergency situation if you can't come up with a simple solution like that. I wish those people luck. (They're going to need it.)

We bought these LIFE BIVY to keep in our vehicle in the event of an emergency on the road. We travel a lot during the winter and like to be prepared with extra blankets, shovel, flashlight, snacks, etc. Although that emergency hasnt happened, thankfully, we tested the bags by wearing them over simple clothing and shoes and sitting outside in PA's 30'F winter. We were still warm and dry after an hour. My husband tucked his coffee mug inside his bag but that produced condensation which made him cold sooner. I could have stayed out there for much longer. The bags pack up very small so they dont take up much space at all, are a comfortable, roomy fit, light and surprisingly very warm. I'll be ordering several more for our children who also drive in the winter. Great addition to our safety kits during storms of all kinds too. I only wish I could convince our cat to sit still inside it with me! Great find!

4.0 out of 5 stars Could be a lifesaver!
Reviewed in the United States on June 6, 2019
Color: OrangeLens Color: 1 PackVerified Purchase
This emergency bivy could definitely be a life saver. It is lightweight and compact and won't take up much room in a pack. I plan to keep it in my hunting pack at all times. Like my emergency medical supplies, and bear spray, its something I hope I'll never have to use, but if I need it, I will be very glad to have it. If I ever get lost or injured, the orange color could help search and rescue personnel find me faster too. I took the bivy out of its stuff sack to check it out and when I got inside it, I immediately could feel my body heat being reflected back. I'm 6 foot tall and I was able to lay down and pull it up over my head if I curled up a little and bent my knees. When I lay straight, it easily came up over my shoulders. The bag isn't super roomy, but it does the job. I was able to fold it back up and get it back into the stuff sack, but it took a little time because the material is slippery and it was hard to keep air from getting trapped in the folds. That was probably just poor technique on my part. The material seems fairly tough, but because it is thin I'd imagine that sharp rocks or sticks might poke a hole or rip it, so I wouldn't expect it to stand up to frequent use. But that's not what I bought it for anyway. I'm keeping it for emergency use only and because its only weighs about 4 ounces, I won't mind carrying it with me. The price is reasonable too and won't break the bank if I need to replace it if it got damaged. If you are a hunter, backpacker, or hiker, I would recommend you consider getting this bivy. Put one in your pack and keep it there, because its cheap insurance against hypothermia and might just save your life.

I have yet been able to use the life bivy. As for durability I don't know for sure how durable it. It does seem to me it is durable enough to get the job done when your caught up in those sticky situations. It is light in weight and best of all it is a small package as well. I like the fact that it has a little bag that can be reused for the bivy, and it has a little whisle on it as well.
I would get it again!

Color: OrangeLens Color: 1 PackVerified Purchase
I just used the bag this weekend. I wanted it for a fishing derby where I knew I would have to take a nap. I wore it on the front of a fishing boat in heavy winds and rain. On day one it was about 50 degrees with rain and some wind. I was kept toasty warm and easily fell asleep. On day two the wind was howling and wind chill was probably in the teens. Once again I climbed in and was toasty and able to fall asleep. I usually get cold feet at home every night. In the bag with just wool socks (I took my heavy danners off) my feet stayed warm!! That was a huge testament to me. The winds were probably 30+ and the bag held together just fine. I was able to fold it up after two days of use and fit it back in it's original bag!! So I give it a 5 on everything!

Adding the Life Bivi recently to my EDC bag, greatly increased my survivability. It's a tiny portable shelter and packs so well in your kit or ties on anywhere, that you'd be silly not to include in your EDC or Bug out Bag. See more at my website if you need but this is an essential item for your survival. Thanks for the great product!

A reusable emergency sleeping bag that failed to work the first time.

I was quite excited to get these last year for my emergency kits. Bought 4 and thought that the higher price would mean quality more than that.
First Tim I use the one for the car, I unfold it carefully and and put my feet in it and pull gently. Within seconds of using it, it ripped length wise as my foot was inserted.

I feel warm for sur but that rip is letting the cold coming in and I now have none to use in the future.
