This Is The Value Choice
I needed something that could prevent snow blindness and not fog up - the Sherpa's passed that test. I have a narrow face that is usually difficult to fit sunglasses to - Pass. Other reviewers note that they scratch easily yes they do. And the nose rest is not the most comfortable as far as sunglasses nose rests go. Since these succeed on the main points that I bought these for, I recommend these sunglasses.
