Nitrogen knows how to make a pair of shades that protects your eyes and keeps you looking and feeling cool at the same time. These nice sports sunglasses for men have polarized lenses that block out harmful ultraviolet rays, eliminate glare and keep your eyes safe when you play outside. The frame is made of plastic, shaped to fit and stay on under rough circumstances. The arms are solid-looking with a slight curve at the rubberized earpieces, and the Nitrogen logo is displayed on the side.
