There is a quilted pullover hood that I believe is made by Refrigiwear. The neckpiece slips over your head and over you shirt's collar. What I like about it is that it allows you to turn your head 180 degrees without any loss of view...that's important when you're watching a load line or any other activity around the construction site. Your cold weather info is great! Not that you would ever find alcohol on a job site or a worker showing up with it in his system or on his person, but alcohol can be the number one cause for serious frostbite. The same with coffee. They can truly accelerate tissue damage. Forget the old story of the St. Bernard's cask of brandy saving lost climbers (mountain, not tower). It's a fable that grows with years. Alcohol and caffeine will accelerate hypothermia, plus there is more caffeine in brandy than most beverages, including coffee.
