It's hard to imagine having a SHTF event when it's the middle of winter, but the truth is when a disaster takes place it's important to be prepared for every circumstance and weather. If a person must flee from their home to bug out they will need to know how to survive.
When bugging out and making a camp outdoors in your only option, you'll need a backup shelter. A backup shelter will help you sleep on the ground even if it's covered in snow and there aren't that many supplies such as trees available to help you make a shelter.
If a tent isn't available and making a fire in these wet conditions is challenging, surviving the night may seem impossible. However, with just a few blankets you can survive through the night and stay warm enough as well.
Matter of fact, having the proper blankets may be one of the most important supplies to own for SHTF.
Watch how a survivalist makes it through the night in sub-zero temps with only blankets. This video on the next page is very revealing as to what is possible if you plan ahead of time!
