Keep your shades or specs at the ready with Tideline Adjustable Eyewear Retainer. The streamlined stainless steel and silicone construction looks great, keeps a low-profile, and is super comfortable and easy to adjust. Swap out the temple ends for a secure fit no matter if your frames are made of thin metal or wider acrylic. Quickly and easily adjust how snugly the retainer rests against the back of your head using the two silicone tabs. And since they take up any slack, there’s no more “tail end” hanging down your neck!
