6 months I have been using them daily and have not scratched, very light and well built, the materials seem of good quality, compared to oakley prefer these with a lens of very good quality and also lightest around but the face. A very good price for a polarized lens. I play tennis twice a week and never fall down my face.
Good fit in medium to big face.
And as I read in another review take the Bolle everybody has Oakley.
