Driving, boating, running, or standing on the sidelines - these sunglasses are perfect for the full spectrum of outdoor activities. Rectangular polarized lenses cut glare, and plastic frames hug the head for stability. Frames are wider at the outer edges, and wide arms contain two small vents to allow for air movement behind the lenses as well as a metallic Nitrogen logo accent. Arms narrow into very slightly curved earpieces. Choose from shiny black frames and arms with black lenses; matte black frames and arms with black lenses; shiny black frames and arms with green lenses; very dark tortoiseshell frames with black arms and black lenses; shiny black frames and arms with brown lenses; or medium tortoiseshell frames and arms with brown lenses. These sunglasses are sold wholesale by the dozen.
