So after a very positive review in the newspaper Men's Health I ordered these glasses, especially for cycling. The glasses are super-light, pushes nowhere and adapts to super. It fits perfectly under the helmet, without pressing. Since I had previously with other eyewear always problems. Also, my old glasses were all not so good and there was still wind underneath, so that the eyes were watering. This is absolutely in this spectacle is not the case. You slip and not a piece, so you do not have to constantly move up. Two staff members of the Men's Health had reported that they have seen better even so than without. I can not confirm, however. There are at even replacement lenses, which I have not yet tried. They seem to be on intensive sunlight.
