I bought my glasses because I have always gone with my normal glasses and but now have a rigid contact lens. It must be realized that the GP lenses can significantly easier from the eye than ordinary "soft" contact lenses. For this reason, I needed glasses to protect very well against wind and has no were sticking. These features meet the super glasses. Even with large people like me to cover the entire eye area, so that I get no problem when I turn my head to the side. In addition, also protects well against splashes from below, for example, when driving MTB coming from the front with dirt. The glasses are also very comfortable to wear from her and felt hardly because it is very light in my opinion. In the model I have chosen a slight darkening is given so that it can be used in winter as in summer. Where someone who is used normally to ride with sunglasses probably resort to this, since the blackout is not particularly strong really.
I've also transported the glasses a few times in my backpack without protection, and so far I can not detect any scratches or the like. Although the glasses at the MTB ride dirt abbekommt and you rub off nothing happens. In addition, I have streaks as compared to my normal glasses no problem with, even if I do not use a lens cleaning cloth, which is great!
All in all, but for the price a great eyewear, both for racing and for MTB
