The spiral hinge and an acetate inner rim

Air titanium, the house's first line from the mid-eighties, introduced the spiral hinge without screws or rivets, as part of a concept LINDBERG created with the architects Dissing+Weitling. The air titanium rim collection carries that line on as a titanium wire frame, and styles with an acetate inner rim gain a stronger appearance while keeping all the benefits of wire frame eyewear.
