Layering has either been around a long time – or (re)-(re)-invented recently.
For the M-43 layering system to work, soldiers had to know how to use it. So military experts developed a layering-education curriculum, which shows how the M-43 became both a popular style and a model for dressing according to scientific principles. During one 90-minute indoctrination class, soldiers listened to a lecture on how to stay alive in the cold and watched a demonstration of how to wear and adjust each item in the M-43 uniform assembly.
Interesting story.
