Costa Del Mar OCEARCH Tuna Alley 580G Glass Polarized Sunglasses

Costa Del Mar® OCEARCH Tuna Alley 580G Glass Polarized Sunglasses are named for a legendary 15-mile-long white strip of sand separating the deep blue Bahamian waters from the shallow bank of Gun Cay, where you can spy tons of bluefin tuna migrating north. Costa and OCEARCH have joined forces to create these limited edition shades because 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. The lenses are made from 580G LightWAVE® glass—the clearest in the industry. Polarized and outfitted with a mirror coating to control glare, they're also scratch-resistant and thinner and lighter than average polarized glass. 580 technology filters out harsh yellow and harmful blue light, making colors brighter and objects sharper. These Costa fishing sunglasses sport durable co-injected nylon frames made using an eco-friendly bio-resin process (using castor oil instead of petroleum). They're outfitted for fishing with nonslip Hydrolite® material for a secure, comfortable fit, plus Costa's signature 3-hole venting system to prevent fogging.
