I like sunglasses but can never find the right pair. Usually they do not stay on or I can feel them on my face or have an obstructed view when looking up, down, and side to side. But with these I have none of that. The grip on the arms hold these bad boys in place and they do not move at all. The rap around lense gives you coverage on all sides. What I like to is that using these on a sunny day on the snow I can use them while doing photography and all my pictures come out the way that I set them up.
