What’s better than black-on-black with a little more black? These triple-duty Fort Knocks are equipped with matte black frames, polarized black smoke lenses, and gunmetal hardware for an undeniably cool design. 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.
