Before modern sleeping bags, WWI soldiers used layering and heat-trapping methods that often retained more warmth than modern designs. This video explains how airflow control, ground insulation, and body heat reflection worked together to reduce heat loss. These techniques didn’t rely on bulk — they relied on physics. Understanding them reveals why many modern sleeping systems fail in real cold and how old methods still outperform them.
