Ocearch

Costa believes in making products with a purpose, that's why we've partnered with OCEARCH® to surface a brand new collection of Great White Shark & Tiger Shark inspired sunglasses, shirts, and hats.

You'll look like a Maverick in Costa's OCEARCH® Half Moon sunglasses, a West Coast inspired beach style that rides the mystique of epic ocean swells. Available in 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.
