Worn these for the past month now and love them. They are tight enough that they stay put even in downward dog and other inversion poses on a paddle board, but remain comfortable after hours of wear.  They are cheap enough that scratches or losses won't upset me, yet when worn they look a lot more expensive. The frames are sturdy, not flimsy like the ones sold on NYC streets.  Classic style that is suitable for most face shapes with a trendy mirrored lens. A great buy.
