How do you figure out whether to get a small, medium, or large size if your are buying online w/out trying them on?
I could be wrong, but I think that the small, medium and large sizes refer to the size of the lens (and not the frame). As shown on the Kaenon web site (http://kaenon.com/product), the large lens extends further down than the small lens. To be sure, I would contact either backcountry.com or Kaenon (the Kaenon web site also has a feature where you can input your gender, fit, sport and environment and it will give recommendation based upon this. Interestingly, the small, medium and large Kore's seem to be recommended whatever your gender and face size)
