Each pair features the classic Fort Knocks silhouette, which is known for its steadfast strength, style, and versatility. These shades are tough: they feature impact-resistant lenses, high-quality hidden spring hinges, and have a comfortable and accommodating fit—they are named after the United States Bullion Depository in Fort Knox, Kentucky after all.
