Whether you're in the city or at the beach, you will need a pair of shades to complete your look. The Bogota Sunglasses in dark tortoise/gunmetal is a fine suggestion! The frame is handmade steel and acetate with nickel free hinges and Carl Zeiss Lenses in a dark brown color. The sunglasses comply with essential requirements of the EU directive 89/686/CEE on personal protective equipment. The filters of the Carl Zeiss CR-39 lenses protect against UVA/UVB sunrays. The sunglasses comes with a dustbag in a white logo box.
