Very beautiful design. Moderate absorption of solar radiation. Definitely heavier (due to the metal frame) and therefore more tiring than those with a different type of frame. Ultimately, I mainly wear them for brown or more formal events, for everyday I prefer ones that are much more comfortable........... Finally, because I initially ordered them with a gold frame, I would like to point out that they creaked a lot and looked completely fake in the hand - the frame was definitely plastic and not metal.
