Serious anglers and outdoor adventures will love the comfort and unbeatable lens performance of Costa Del Mar Zane 580G Polarized Sunglasses. Named after one of the most prolific fisheries in the world, the Zane Grey Reef, Costa Del Mar Zane Sunglasses are built to go hard with an edgy frame design made from co-molded Hydrolite material with specialized, non-slip temples that are built to perform in the harshest conditions on the planet. Zane Sunglasses are designed with 580 LightWAVE glass lenses, which, in addition to providing 100% polarization and 100% UV protection, also incorporate an advanced filtering compound into the lens material to reduce yellow light. The result: enhanced colors and greater visual acuity in all conditions. LightWAVE glass lenses are 20% thinner and 22% lighter than typical glass lenses but they still exceed federal standards for impact resistance. The optically correct Costa Del Mar Zane 580 lenses also feature both a water-repellent coating and an anti-reflective coating. Includes manufacturer's lifetime warranty.
