You know things are getting bad ass in the fog fight when a 2 speed turbo fan is part of the Smith Phenom Turbo Fan snow goggle. Operated by a single AAA battery (with a life of around 50 hours) the turbo fan stops the production of fog before you can blink an eye.
Smith worked hard at this program alongside military personnel and their technology leads the way in this field. The fan silently draws air across their fabulous Spherical Carbonic-X lens, so even when you're standing at the lifts the fog never descends.
Additionally the Phenom goggle runs with both their TLT lens technology for crystal clear vision and their Patented Porex™ filter that prevents optical distortion during changes in elevation.
