[$60] No, this man is not an extra from a crappy Mortal Kombat movie, and despite it’s name, the mask he’s wearing is not a prop. It’s called the Subzero Warm Breath Mask, and it may very well save your life (or at least your lungs) if you’re planning any high altitude climbs or cross-tundra treks. The Subzero Warm Breath Mask uses a unique ventilation system to create a microclimate chamber that’s 40 to 60 degrees warmer than the surrounding air, and with up to 80% humidity. While the mask is great for extreme climate feats like mountaineering, it’s also great for people with bad asthma that reacts to dry winter air. And thanks to some clever design features, you don’t have to worry about moisture building up on your face or fog forming on your glasses.
