Small metallic details and narrow framing help these sunglasses create a subdued, yet classic look. A small X-Loop logo near the top, right corner of the rims and tiny silver bolts on the left and right side of each lens are subtle enhancements. The narrow, shark-fin arms, skinny double bridge and semi-rimless frames combine to build a surprisingly durable construction. Polarized lenses and multiple color options make these an easy sell. These sunglasses are sold wholesale by the dozen.
