Product DescriptionHoning your technique is the key to mastering fly fishing - and also how we approach the craft of making sunglasses. That's why these sport frames have patented vents on the side to make sure that, when things heat up, your lenses stay crystal-clear. And even when the wind's blowing, their integral hinges will keep them steady and in place.
Each pair of Costas features 100% polarized lenses, providing complete UVA, UVB, and UVC protection. Lifetime warranty against defects in materials and workmanship.
