In case of emergency (blankets)

I camp a lot and have a cabin in Maine that is off grid.  I try to be prepared in case I am caught without heat and have to spend some time waiting for heat (or rescue).  This 5-pack of mylar heat blankets and survival whistle are small and easy to store in the car, cabin or even a handbag. 

One could also use them as a reflective signal for locating help.
