The Smith Universal Cord Retainer is a sunglass retainer focused on security. Smith lists it as fully adjustable with a universal fit, so it suits a wide range of sunglasses frames. It’s a simple add-on when you want to keep your glasses accounted for and close at hand, rather than loose in a pocket or on a hat brim. Across the range we sell, the key features stay the same: an adjustable cord and a universal fit.
