CliC Flex has a revolutionary new redesigned headband - part TR 90 flexible material and part rubber with wire core. This allows the wearer to adjust the depth and width of the headband for a custom fit, all the time.
TR-90 is a thermoplastic polyamide that is light and flexible yet itís super strong with memory so the frames return to their original shape after being flexed. Under severe testing conditions, TR-90 keeps its properties in both low- and high-extreme temperatures, making it the ultimate performance material for sunglasses. Itís also hypoallergenic and is FDA approved. TR-90 frames are adjustable when a metal core is added to the temple.
This frame is so new we don't have a lot of feedback on it yet. However one of the "right-hand-women" of the inventor of CliCs says it's her new favorite frame. She has gorgeous curly long red hair that can interfere with the regular CliC headband--- she says the Flex is perfect for her because she can bend and shape it to follow her hairline exactly and keep the frame from interfering with her hair.
