I love these sunnies! They are so functional and look pretty damn cool, too. They fit me well. cut down the bright glare of Sierra sun, still work when it’s a bit overcast and keep the wind out of my eyes. I rode my MTB yesterday on pretty dusty single track in +20 mph wind and didn’t get any dust or wind in my eyes. I have the Spinshield Air, too, but the Thunder fits me better. I don’t find smudges from my face on the lenses.
