The spectacle has clearly gained to its predecessor, which I have since 2 years to surface. This means in my case long bike runs no more sore eyes, what was the case with the old. The ventilation system works great. The glasses will quickly free when they make up for the increase of the jersey. The mechanism for folding in his face, by a rotating mechanism between glasses and bow, is still the old mechanics. This had gone first broken with the old glasses and was the reason for the new purchase. I hope that keeps longer this time. Actually, I do not need it. Adapting to his nose still works well. The glasses also sounds a good. Depending on the user type you like the perhaps darker, for me it fits. The speed of sounding is oriented to bet the edge retention. One tunnel entrance is not up (would be great).
