There is no worse fate than having your lenses fog up when you're barreling down a busy ski run, except maybe dropping your eyewear while trying to clean it on the lift. The Smith Turbo Constant Air Management (CAM) goggles (left), which cost $150, will take care of both problems with a defrosting system that works even in severe weather. The goggles are a particular godsend to eyeglass-wearing skiers, who often find themselves trying to see through two sets of foggy lenses.
A lightweight battery pack mounted on the strap powers a tiny plastic fan built into the top of the frame for up to 40 hours. The low setting helps to keep your face from sweating and reduces condensation. The high setting will blast away momentary fog-ups. While the noise of the fan is barely noticeable on low, it sounds like a Hoover in your hair when it's running on high. Still, the goggles are comfortable and snug-fitting, and the big noise from this diminutive device seems a small price to pay for an unimpeded view of the slopes.
