As soon as I got this I had to see it. Out of the bag and opened it up. It is going to be a great save in my vehicle. You never know when you may be stranded or need to stay out in the open this just pops out of the bag, rolls up as easy to return it there too. I like that it is made of mylar, it will hold body heat well. A survival must have for our cold winters and needing assurance while out traveling the roads.
