Boss 1855/SThese BOSS sunglasses are trend defining, with their decisive style. The bold square frames are sure to take centre stage. The temples are no less notable, with a visible metal core enriched by the laser engraved BB print. The metal insert at the hinge further contributes to their contemporary aesthetic. Crafted in eco acetate, a material which comes from renewable and recycled resources, these glasses can be fitted with prescription sun lenses.
