We throw on the Sampan 580G Polarized Sunglasses for life on the water thanks mainly to the fact that they give superior eye protection to lesser shades. Named after traditional Chinese fishing vessels, these shades are built for adventure, what, with the polarized lenses eliminating glare and boosting our optical clarity to help us track fish in the water. The classic styling and lightweight construction are at home on most faces, while the 580G glass lenses provide crispy vision and resist scratches from normal wear and tear.
