Backpacker Fact-Checker, #2: Heat Loss Through the Head

This video series will take a skeptical look at some of the Trail Tales told frequently about backpacking, often without evidence or references. In each episode, I’ll do my best to try and track down the source of each claim so that you can make your own, informed decisions about the truth and/or usefulness of the supposed information. Episode #2 examines the familiar rule that “40 to 45% of your heat is lost through your head”.
