The product that started it all, just got better! Why wear other eyewear retainers that hang on your neck, soak up sweat, get dirty, stinky and fray? Cablz are unique in the way that they do not lie on your neck, distract you or irritate your skin, and now they are ADJUSTABLE! Adjustable Cablz Zipz are designed to be worn fully extended or zipped in for a closer, more secure fit.
