Don’t let the cold take your breath away. The OccuNomix Expedition Balaclava powered by Cold Avenger® protects airways and skin and allows for more natural breathing in bitter weather conditions. Embedded with a state-the-art, patented Cold Avenger® ventilator that dynamically mixes the outside cold, dry air with insulated air, resulting in inhaled warm and humid air. Workers can stay outside longer with an in-mask temperature 40°-60° warmer than outside air with no lung freeze. Constructed of breathable 100% polyester, anti-pilling fleece for comfortable protection from wind and cold.
