Costa Permit 580G Polarized Sunglasses Black. Do you need a pair of fishing sunglasses that will enhance your view and stay securely on your faceThis might just be your lucky day.The last thing you want to have happen while you're hoisting that trophy marlin over the transom is for your favorite pair of sunglasses (in this case your new Permit Sunglasses) to go swimming without you. Costa not only designed them to provide exceptional clarity and protection, they gave them co-injected Hydrolite nose and temple pads and flexible hinges so they'll remain firmly in place. Although, if you want to be extra sure they don't end up in the drink, a neoprene retainer or leash (sold separately) is inexpensive insurance. A trio of large vent holes can be found on each side of the frames that will help prevent fogging, plus convey your tenacious attitude. Everything about these sunglasses is focused on improving your view on and around the water. They're extremely durable and reliable thanks to their heavy-duty TR-90 nylon frames made with resin from the castor plant. This bio-based resin offers a 70% reduction in emissions over petroleum-based resin, helping to reduce the overall carbon footprint. 100% polarized, scratch-resistant 580G Lightwave glass lenses ensure reflective glare and eye strain are minimized or eliminated altogether.
