The first time I tried these glasses, they seemed to me not very stable and jappréhendais use in running. But nay, in reality they hold very well and do not move, be it in running, cycling, mountain biking.
These glasses cover well and perfectly protects the eyes from the sun.
The only negative that does not give it the 5th star and difficulty change lenses, at least the first time. The technique is to place the beakers to the perpendicular of the frame and to rotate at the middle of the lenses. (View the photo)
