The thermax headband is constructed of 100% hollow core thermax polyester that prevents heat loss by trapping a layer of warm air. At the same time, it transports perspiration to the outer layer of moisture absorbing fabric to keep you dry. It covers ears well and keeps you dry and warm in cold weather.
It is a great headband for everyday use in moderate cold weather or active sports in cold weather.
It is also supported by wigwam and its 110+year history and reputation as a quality family owned business that stands behind their products.
