The AI1XS is the little sister of the essential AI1. It's still a sleek eyewear with a futuristic design echoing the sporty lines of the 80s. The temples are made of Grilamid TR90, a light, resistant, flexible and comfortable material, and the lenses are impact-resistant. This model is ideal for slim faces. All Mundaka eyewear features CE-certified lenses with 100% category 3 UV protection.Frame:Material: Grilamid® TR90Colours: BlackLenses:Polycarbonates CX Impact-resistantAnti-fog and hydrophobic treatmentColour: Grey / Grey mirror effectCategory 3 - 100% UV protectionBase 8Dimensions :Face width: 135 mmLens height: 63 mmBridge: 15 mmTemple: 118 mm
