 My name is Rick Barber. I am serving as a cold weather instructor after attending the Allied Winter Instructor course in Elvirum, Norway. One of the unique things that I learned while working with the Norwegians is to not shave when in an arctic environment. The reason for that is shaving actually strips the oils off your face. It makes you more susceptible to cold weather injuries. The Marine Corps issues sufficient warming layers. However, the Norwegians use wool warming layers that have fishnets within them. They create air pockets that uses a person's body heat to actually warm them more efficiently and optimally.
