Like the stormy Mediterranean, after the sirocco wind blows through, these polarized sunglasses are wild and untamed. Deep grey fronts combine with a light blue interior on the injection-molded frames, and polarized aqua lenses provide UV400 protection. Fort Knocks are our durable, form-fitting frames that are as tough as their namesake. With metal accent bars on the front, hidden spring hinges, and a design made for medium to large face shapes, Sirocco Fort Knocks sunglasses are instant favorites.
