If you are planning to hunt in the cold, you need the Under Armour ColdGear Infrared Tactical Hood in black. This hood is made out of an insulating material that will keep heat from escaping. It is one size fits all for maximum comfort and effectiveness. At only 0.13 of a pound, it's so light that you'll hardly notice it. This hood, also known as a balaclava or facemask, is also excellent for hiking or camping during the winter cold.
