Frame details
CARIN AIR B in the pictured black colorway: a unisex round-square (a square outline with softened corners) cut from lightweight TR plastic with titanium temples. The rim profile is slim and matte, with the bridge integrated as a flat top crossbar. Adjustable silicone nose pads sit on short metal arms, uncommon on a plastic-front frame and helpful for narrow-bridge fits.
