The polarized lenses on these masculine rectangular shades make them perfect for activities on or near the water because they cut glare and improve visual acuity. Plastic frames include a molded bridge and top bar as well as molded nose pieces. Frames are slightly curved to hug the face. Slender arms are attached at a metallic hinge, with the Nitrogen logo boldly emblazoned on them. Clear color accents occur along the top and bottom edges on two of the color options available for this style. Your order will include a selection of all four color options available in this style. These sunglasses are sold in bulk by the dozen.
