I won these sunglasses in a kayak fishing tournament, so I did not pay for them directly. They have the amber/brown tinted lenses that I really like for fishing our clear streams and especially for days when it is cloudy. They are lightweight and have held up well to regular use. I've had them over a year now and they've become my go to glasses. The lenses deliver a sharpness and crisp clear definition that is definitely noticeably better than some of my other cheaper shades. I would certainly put them on par with Costa or Oakley and they are about that price. They advertise that they filter more UV than Costas, though I can't say I've verified that objectively. Check 'em out if you're looking for some premium lenses in the $179-$279 range.
