--I tried on a bunch of Oakley goggles and these were the only ones that fit the curve of my face--no pinching and no gaps. They are also very comfortable.
--I have worn them in many conditions -- snow, bluebird, even rain, and have never had them fog up.
--I have the G30 lenses, which are pretty great all-around lenses. They do great in bright light and medium light, though on really dark, cloudy days, the contrast is a little low and I recently got Stockholms with persimmon lenses. Persimmon was better, but still not great with the low lighting -- I'd recommend going even to yellow for that.
In general, they are some of the most feminine style, fit the female face, and are also a functionally great piece of equipment.
