Great goggles, fit well with my Red helmet or with just a beanie. So far no fog issues, even on warm, sweaty days on the hill. Ignitor (rose) lens works well in various conditions, the gold lens is ok, not really worth the hassle of changing lenses. The adjustable venting actually works, and works well to shut out the cold on a 5 degree windy day or keep you cool on warmer days.
You get what you pay for...The giro helmet looks great in a box, or on a shelf, but on your head you'll look like Dark Helmet from Spaceballs. The fit is about right, but there is hardly any adjustable padding, in fact there's hardly any padding at all inside. Mine nearly fit, if there was more padding it would have been ok, but the hard foam inside gives a solid headache after a few minutes. The price is great, but if your melon doesn't match up with this helmet just right you're screwed. Overall, fit isn't great and the whole thing seems cheap when you look at it in person.
