The Subzero Warm Breath Balaclava

This is the fleece balaclava preferred by high-altitude mountaineers and Antarctic scientists because it humidifies and warms winter air for comfortable breathing. A special ventilation chamber in its integrated mask lets wearers inhale full, unhindered breaths while trapping a small amount of heated, humid exhalation. The result is a comfortable, fully oxygenated "microclimate" inside the mask with humidity up to 80% higher and temperatures up to 60° F warmer than outside air. Medical studies by the American College of Sports Medicine show such a microclimate is healthier for the lungs, as excessive exposure to cold, dry air can trigger asthmatic symptoms. The soft and durable, medical-grade, microbe-resistant polyurethane in the chamber bonds with the humidity in the air, keeping moisture off the face and preventing fog on glasses and goggles. The balaclava itself is breathable, wind-resistant Polartec fleece, with hook-and-loop flaps shaped to fit comfortably over goggles and helmets; allows wearer to remove chamber without removing the balaclava. One size fits all. (1 lb.)
