The frames of these Xezo Architect sunglasses are made of pure, 100% titanium (a material with the highest strength-to-weight ratio of any metal), are nickel-free, and are non-allergic.
The lenses are made of a polycarbonate material which is impact-resistant, scratch-resistant, and polarized for most models. They offer above 99% protection against the harmful effects of ultraviolet (UV) radiation. These lenses can be replaced with prescription lenses by an optician, should this ever be required.
Xezo titanium frames are produced in limited editions for most of our models and select models are individually numbered.
