The story behind the frame
The Fathom is a classic rectangular frame from Costa, a Florida brand founded in 1983 by people who fish. Its copper 580P lenses increase contrast in lower light, making it well suited to early mornings, late afternoons, and cloudy days on the water.
The clean design also works for driving and everyday wear. Read how copper and other lens tints differ in lens colors explained.
