That isn't to say it shouldn't be covered though. Thanks for posting. Good tips.
Here is an article regarding heat loss from the head.

Interesting article. So when you start a strenuous exercise, blood flow increases to the brain, accounting for 50% of the body's heat loss, but then demands from other parts of the body, muscles, skin, reduce the flow to the head. The 50 to 70% heat loss adage is attributed to the chimney effect from the clothing going up to the shoulders, neck, and head. Not internal heat loss. So I should have said that 50 to 70% heat loss occurs around the head, neck, and shoulder area.
