Save the seas.

Half Moon Bay on the California coast is well-known for its big waves—and even bigger sharks. Whether you're headed there to surf swells or seek out Great Whites, you'd be wise to have the Costa Half Moon Ocearch Polarized Sunglasses with you when you do. A collaboration with the shark researchers at Ocearch, these sunglasses features lightweight polarized lenses that eliminate glare so you can see below the surface of the water more clearly. Straight temples and integrated Spring Hinges offer a comfy fit, and Hydrolite nose and ear pads keeps your shades in place when the sea gets rough. Best of all, a portion of the proceeds from these sunglasses go towards funding future Ocearch expeditions and their mission to protect sharks and our oceans.

    New Go To Fishing Glasses

    • Familiarity: I've used it several times

    These have worked great for cutting through the glare on the water and being able to see the bottoms of the creeks I fish in. They are light and extremely comfortable.
