The N-Ferno 6952 Winter Hard Hat Liner has 3 layers of insulation with a quilted nylon outer shell, a foam mid-layer and Sherpa lining for extreme warmth. This lightweight thermal liner is shoulder-length to keep head, ears and neck covered and fits comfortably under helmets or hard hats without feeling too bulky. The 100% polyester Sherpa lining has all the benefits of a real sheep's wool to keep you warm with less bulk and faster drying.
