These are my third pair of goggles and they are by far my best pair ever. My second pair of women-specific goggles, these have a wider lens, which I appreciate. They fit great with my Giro Helmet, which I was a little concerned about. I have the Sensor Mirror lens which is awesome. Some that I have worn them, the days have started with super flat light and turned into a blue-bird days and it works great in both conditions. I have also worn them while working really hard, when my other goggles would always fog - and these haven't fogged on me yet! They are very reliable, which makes them VERY enjoyable! I love 'em!
