Good but not as big as expected
Good glasses. You gotta love the coverage these things give you: Absolutely no frame in your field of view at all. They're head and shoulders better than anything else for that reason alone. No sunlight gets around the edge to give me a headache on long hikes and nothing interferes with my peripheral vision on the motorcycle. My gripe with them is the back portion of the arms. Both arms curve inward quite a bit. This keeps the glasses on but sort of pinches if you wear them for a protracted period of time. I'm doing a little heat gun work on 'em to see if that fixes matters.
Oh, also, the Silver color with reflective lenses makes you look like the visitor from the future in a low-budget 80's sci-fi movie, which rules.
