The frame is made of plastic, strong and durable with a lightweight construction that gives a comfortable fit. The arms start straight off the temples and taper to a two-panel textured section. The Nitrogen logo is seen in silver lettering on the side. The lenses are rounded rectangles with a dark polarized finish, perfect to protect your eyes from the sun and its glare.
