In my Belt Survival Pouch I keep a 55 gallon drum liner and a space blanket. In my daypack I keep a heavy duty Stearns poncho with grommets that can easily be improvised along with another 55 gallon drum liner. In my BOB I keep an orange tube tent with two more 55 gallon drum liners and a space blanket. I am ditching the space blankets for some Survival Emergency Blankets by Adventure Medical Kits in the near future.
