Subzero Warm Breath Mask - - Fleece Mask Preferred by High-altitude Mountaineers and Antarctic Scientists

This Subzero Warm Breath Mask is designed to recirculate a portion of your exhaled breath to warm up the incoming air and make for a pleasant breathing experience, even in the coldest Arctic temperatures. Anyone who’s been trapped in a cold spell can attest to the unpleasant nature of icy air, so this sounds like a perfect solution. Shame it makes you look like a mutant Droid from the Archeton Theta galaxy. $59.95.

This is the fleece mask preferred by high-altitude mountaineers and Antarctic scientists because it humidifies and warms winter air for comfortable breathing. A special ventilation chamber 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 up to 80 percent humidity and temperatures 40° F 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.
