THE OCEARCH HALF MOON STORY You'll look like a Maverick in Costa's Half Moon sunglasses, a West Coast inspired beach style that rides the mystique of epic ocean swells. Available in Shiny Black and Tiger Shark as tributes to the Icy water, huge swells and some of the largest sharks in the world that frequent Half Moon Bay. With straight temples, double-cut textures, and integrated Spring Hinges combine outstanding function and comfort with beautiful aesthetics. The sporty beach style of Half Moon embolden the thick, ominous waves of the legendary Mavericks surf break.
Sharks are in trouble, and without them the ocean ecosystem could collapse. Your purchase helps fund research expeditions aboard OCEARCH, a marine vessel and at-sea laboratory that generates critical data and puts science on the side of sharks. Explore the Case >
