    Love the Fathoms

      Best pair of sunglasses I've ever worn. I was relunctant to spend so much money for sunglasses, but after trying a pair, I can't imagine going back. The glass lenses are so clear. These are very comfortable. I sometimes forget I have them on. I was able to get them at a good price at Backcountry.com. I highly recommend the Fathoms!

      Costa Fathoms

        These sunglasses are amazing. I have used them from the coast of the USVI to the top of Whistler mountain and skiing in the back country. They have held up to many days and eves of drunken debauchery and a few sticky fingered girlfriends. They always seem to want to snag my shades. Anyhow if you are looking for and extremely lightweight, comfortable and durable pair of sunglasses these are it !! Not to mention Backcountry.coms amazing satisfaction guarantee.

        Write your question here...Can I get the Fathom Polarized Sunglasses in the 580 lens? Thanks Tony

        do you have these with black frames? also...

        do you have these with black frames? also compared to the hammerhead, are the lenses the same size? i've tried on the hammerheads, they fit my big head pretty well, are the fathom the same size? thanks, george

        The fathoms are a smaller lens than the Hammerheads, and the frame is much lower profile/coverage. This is a medium lens size with a lightweight thin frame, whereas the Hammerheads are large lenses with a very large wraparound frame. Hammerheads are great at peripheral light blocking. You might look at the Man-o-war for a larger Costa with good coverage.
