Hot Rox heat exchanger mouthpieces are newly introduced to help you stay warm in extreme cold.
The devices capture heat and vapor in your exhalations — then warm and humidify air for return to your body during inhalation.
With an 80% efficiency rate, new Hot Rox effectively keeps core body temperature in a safe zone on frigid days. Breathing warm, humidified air from the mouthpiece also slows dehydration plus reduces risk of hypothermia and overall body stress, the maker declares.
