Review: Small bit of preparedness - Have you ever had your car stall in snow country? I have. That's why these were added to my in-car emergency supplies. They are small, easy to pack, and appear to be of good quality. Luckily, I haven't had to use them, but it doesn't hurt to be ready. Even if one doesn't have an emergency pack, these can be tossed in most glove compartments.
Review: Emergency Sleeping Bags - These are really small and were bought to put in our But-Out backpacks. I did hear from a person I know who lost their power this winter during the bad snow storms. They said that their little emergency sleeping bags were a life saver. They used them along with their regular sleeping bags and said that they stayed really warm. During the day they got into the bags during the day while they sat for meals and while they were talking or reading and were so happy they had them to help them stay warmer.

## Questions & Answers

**Q: Has anyone tried these from this company and how they stack up to the bivvy?**
A: I think the bivvy is a better quality. These are slightly cheaper. It will get the job done in a pinch but it is still prone to rips easily. I hope this answer helps in your decision. Thanks.

**Q: Are they reuseable?**
A: Yes, they are reusable if you are careful when first using them. Obviously, they are subject to tearing if used roughly or stored carelessly. They are meant to be used in an emergency when expedited action is indicated -- like in a sudden and unexpected evacuation order.

**Q: What temperature are these rated to?**
A: It is in my bug out bag and I haven't looked at it in quite a while. I know I got it rated for Alabama weather so prbobably 15-20 degrees maximum.

**Q: What is the exact measured thickness of one side of the sleeping bag?**
A: I'm not sure, but it's main purpose is for emergency buyout. It can be used more than just one time. So it is RIP resistant, pretty strong.
