I use Oakley Crowbars, and I'm going to be buying another pair for the coming season. I've got a medium sized face and a broken nose, and the fit is the best I managed to find.
But goggle fit is very dependent on facial structure and size, so if possible try and get to a shop to try some on. If not just have a look on the manafacturers website, they usually have some kind of rough fit guide.
Smith I/OX - I literally have tried everything to try and get these to fog up...and they just won't. Comfortable too, lens is very easy to change, the list goes on and on as to why I will ONLY use this goggle.
I really like my air brakes by far the best goggles I have owned. I have also had a frames, crowbars, io's and some spy and dragon (cant remember the name of either) and I just find the air brake has by far the field of vision and I think Oakley make the best lenses. But yeah go try some on And see what fit you best. Remember to take your helmet too.
