Inside this mask is a patented heat exchange module. As you exhale, the air leaving your mouth is directed from the mouthport through the modules chambers capturing the heat and water vapor from your exhaled breath. When you inhale, the cold air travels back through the modules chambers picking up heat and water vapor, warming the air. One size fits all. Color: Breakup
