Adjustable Cablz Zipz are designed to be worn fully extended or “zipped” in for a closer, more secure fit. This eyewear retainer is unlike in the way that it does not lie on your beck, soak up sweat, get dirty, or fray. They are made with coated stainless steel cable and are available with Universal Ends or XL Ends. Zips are durable, lightweight, and allow a full range of motion.
