I had to replace the ear/temple tip on a pair of Serengeti Driver aviators. There's no factory service, of course, so my quest began here. Now these glasses have very thin wire ear pieces, stiff but still easy to bend with too much force. The first tips I tried were much too inflexible and could not move past the curve in the earpiece. So I went looking for something more flexible, and tried these Behline tips next.These were much more pliable. The inside opening was a perfect fit for the thin Serengeti wire frame, slid right on without any problem and stayed put. The angled tips look like an OEM item, they complement the frames well. Excellent product for this kind of frame.
