I use these for my daily bike commute; the fototec means that I can even wear them when it is fairly dark out, so I no longer have to take multiple pairs of glasses to work. Good eye protection, reasonable sun protection, and they don't slip or interfere with my helmet. I am satisfied.

EDIT: One caveat is that the nosepads are easy to dislodge, especially if you are prone to fiddling with them. I hear some people superglue them in; I am not ready to go that route.
