Costa Del Mar® Blackfin PRO 580G Glass Polarized Sunglasses are an upgraded version of one of Costa's most trusted frames, building off of the original by adding 6 angler-friendly enhancements. These fishing sunglasses feature durable co-injected nylon frames made using an eco-friendly bio-resin process (using castor oil instead of petroleum) to reduce emissions and overall carbon footprint. The frames have been improved by adding a vented, fully adjustable, stickier Hydrolite® nose pad for a custom fit. Costa also added sweat channels and eyewire drains help keep your vision clear, plus side shields and hooding to block peripheral light. Finally, new metal keeper slots keep your frames and your focus locked in. Polarized and outfitted with mirror coatings to help control glare, Blackfin PRO sunglasses boast 580G LightWAVE® glass lenses—the clearest in the industry. They are also scratch-resistant and thinner and lighter than average polarized glass. 580 technology goes beyond polarization to produce the best lenses on the planet by selectively filtering out harsh yellow and harmful blue light, making colors brighter and objects appear more defined. Costa Blackfin PRO sunglasses include a case, a cleaning cloth, and a mfrs. limited 2-year warranty.
