Costa Del MarMens Rincon Fishing and Watersports Sunglasses (pack of 1)

Are these available in the "smoke crystal" frame with the green lenses?

The sellers verify this is a new item but what do the glasses come with overall?

Do you have the frame option matte atlantic blue with grey/silver mirror glass lense? i do not want the standard grey lense and i do not want poly.

Why are these cheaper than on the costa website or in retail? are they real?
