Gear Review: Smith Turbo Fan Goggles Clear the Fog

Smith Turbo Fan Goggles

The Turbo Fan series of ski goggles from Smith Optics do exactly as they promise: The built-in fan keeps the lenses on the goggles clear so you can see where you are going at all times. While they’re a terrific choice for any skier, snowboarder, or athlete who spends time outdoors in the winter, they are also an incredible gift for people who wear eyeglasses as well, providing the same benefits to that crowd too.  

After years of wearing contact lenses, I literally found myself in a fog the first time I wore eyeglasses under my goggles on the ski slopes. Between the powder falling from the sky and the body heat generated while skiing though the bumps, every time I paused my goggles fogged up so quickly and completely that I had to take them off in a vain attempt to dry the lenses. It was a frustrating experience to say the least.

Thankfully, Smith Optics offers an ingenious solution to this problem in the form of its Turbo Fan line of goggles. These models come equipped with a tiny, quiet fan that is built into the frame that helps to vent out excess heat and moisture. That fan runs at two speeds and helps to keep glasses clear even when skiing during a heavy snowstorm. And If the goggles start to fog over when you come to a stop after a hard session, just slide the switch to a higher speed for a few minutes and soon you'll have a clear view of your surroundings once again.


There are three models of Turbo Fan googles available —the Prophecy, the Phenom and the Knowledge OTG – each with a different style to fit your own sense of fashion. The first two are medium sized for those who don't wear glasses, while the Knowledge is designed to slip comfortably over a pair of spectacles. That said, people with smaller faces may be able to fit their glasses inside the Prodigy model, as it still provides a bit of extra room. If not, Smith has an Ocular Docking System that fits inside most Turbo Fan models, bringing a higher level of versatility to the eyewear.


The Bottom Line

If you've ever found yourself forced to stop mid-mogul on a ski slope because your goggles have fogged up and you can't see the bottom of the bump, these googles are for you. Alternatively,  if you're in a snowstorm and have a personal white-out from fogged glasses you'll want to own a pair of Smith's Turbo Fan goggles. Quite simply: They quickly and efficiently clear the foggy air so you can see where you are going, making your ski outings safer and more enjoyable as a result. If you're a downhill skier, snowboarder, or snowmobiler who wears glasses that fog when you're active, check out the Ocular Docking System.

It's an insert in which you can put your own prescription lenses and still take advantage of the Turbo Fan system.
