Bruce Zawalsky, Author of Canadian Wilderness Survival, focuses on one important type of survival gear, Insulated Mattress. An Insulated Mattress is Critical item #13, not essential like the top 8 or hard to replicate like 9 and 10, but important to survive complications like a broken leg or very cold weather when stranded in the northern wilderness. Bruce talks about the difference between how a self-inflating mattress or Ensolite foam pad will insulate you from heat loss due to conduction, add insulation to or replace an evergreen bough bed, and is available quickly in an emergency for any cold-weather outdoor activity or survival gear.
