The matte gunmetal frame and gloss silver accents of the JS Hawk Gunmetal retain the frame’s classic style while adding a twist of individuality. Gloss tortoise Italian acetate temple tips add another subtle differentiator, and polarized gray lenses complement the gunmetal frame. The frames are crafted from nickel-free stainless steel, and each frame is individually hand-polished and assembled. Soft silicone nose pads are used for extra comfort and are attached to malleable nose pad wires to easily adjust fit. German-engineered 3-barrel hinges and screws are used to retain smooth movement for years to come. Our lenses are made from an impact-resistant CR-39 that provides incredible durability and exceptional visual clarity. Polarized lenses come standard.
