I'm a road rider that is looking to purchase a new pair of sun glasses. I believe that I would fit in to the "large face" category. To date, any of the glasses that I have tried on have been too short in the temples or too narrow. Any advise/thoughts/ideas regarding fitting shades on my size 8 cabeza will be appreciated. I am hoping to purchase online, as the selection at my LBS and other shops are either too limited or too expensive.
