Taking their name from the Zane Grey Reef, the Costa Zane sunglasses are named in honor of one of the most prolific fisheries in the world. And with co-molded Hydrolite™ temples they're always ready to go. 100% polarized and built for performance with mirrored lens options, these Costa men's Voyager and Angler sunglasses are ready for a day fly fishing or adventuring through the deep sea.
