I bought these goggles for my last snowboard-trip to Austria, and I had a good success with these; Why I choose these were because of the nice price, and 'cause of the slim look of these lenses. They don't fog at all, they protect against the sharp sunlight, only thing you'd be aware of, is that they are bigger than most other goggles! Guess it's a goggle for those who wear glasses. But fits perfect for those without glasses too though!

Well, I got these goggles for a couple reasons: I have a huge noggin and Smith's lifetime warranty.
I use a Giro 10 helmet and these goggles fit very nicely! I've used them on 2 separate trips and I have never fogged! My girl and her Bolle kept complaining that she couldn't see. Sucks for her! Get these Gogs!

I'm stoked on the Knowledge OTG. Fits over my glasses very well, hasn't fogged on storm days or hikes, and the Gold Lite lens works well in sunny to mildly flat conditions. I bought the yellow replacement lens for flat light days.

Very pleased with this product. Fit over my glasses well. Also worked nicely with my Giro G10 helemet. My glasses did fog, but that is no reflection on the goggles.

Great goggles. They fit perfectly over my glasses, and my glasses rarely fogged. Great buy.

These are the first goggles I owned and they’re extremely comfortable. Great peripheral view. Greater than even my glasses! Comfort and padding wise, I would say they are on par with the Oakley A-Frames, which I couldn't wear due to my large noggin but these fit perfectly. Never fogged, although I wish I could say the same for my glasses. Be careful when cleaning them though, I was stupid and wiped it when it was really wet. It can damage the anti-fog layer, and now mine is all splotchy.

These goggles were acceptable. They fit well over my glasses. The goggles never fogged up, but my glasses did so the result was the same. They also seemed to fit too low on my nose restricting breathing. They are well constructed and work as intended. I just wish there were more choices for those of us who wear glasses. I guess it's time for Lasik.
