Goggles fit wheel and excellent for sunny days and can even cope with some lower light levels. The only slight downside is the external lens surface does mark quite easily. For the money, I'm very pleased, if I was paying £100 plus for Smith, Oakley or similar and the same happened I would be well p'd off. I'd say these were good value and look good. Venting wise they performed very well and didn't fog up once despite the temperatures being very low.
