To start off I must say that luckily for me I have not had to use an emergency blanket or the Blizzard Survival bag in an actual emergency but I do know the value of having one. The Blizzard Survival brand of emergency protection gear has done a nice job in creating a product that works. Their thermal protection products have a lightweight and compact design, making them ideal for taking with you on a hike, climb or even have in an emergency preparedness kit.
