It's the negative space that makes these unisex shades so fun and interesting. Metal wire rims surround mirrored aviator lenses, but leave an open crescent along the outside edges. This opening works as a vent as well as an attractive design feature. Thin metal arms angle into simple earpieces. Black gradient, light gray, brown, and dark multi-hued mirrored lenses add additional color along with UV400 eye protection. Each order includes a selection of all four color options for this style. These sunglasses are sold in bulk by the dozen.
