Abstract
A helmet is particularly well suited for cold-weather use. The helmet includes a jaw shield that is detachable from a head portion. A breathing mask connects to the jaw shield via a mask adjustment mechanism that selectively axially moves the breathing mask toward and away from an inner surface of the jaw shield to precisely and accurately position the breathing mask against the nose and mouth of the helmet's wearer. A spring-loaded quick-release tinted shield is controlled by a lever that selectively raises and lowers the tinted shield. An eye shield pivotally connects to the helmet and is disposed in front of the tinted shield. An eye shield heating system on the eye shield electrically connects to the head portion of the helmet to provide electric power to the heating system.
