Mylar is a reflective material often used in super shelter and as fire reflectors. It is also quite often used as a survival blanket or as some form of heat retention in sleep systems. No one can seem to agree on the proper use of it or in what ways to layer it. I decided to make a video on the different options for uses and layering and I would LOVE to have a bunch of comments and discussions and opinions on how y'all have used this stuff.
