A versatile strap that can be used either to secure eye wear to your head, or as a neck strap for keeping your reading glasses etc. handy.
The strap is made from a quality, lightweight nylon material. Each end terminates in a rubber loop assembly, which makes a simple push-fit onto the arms of your sunglasses or glasses. A small wire ring can then be pushed up to tighten the strap onto the arms. The strap can be adjusted in length by means of a sliding toggle; when adjusted to suit, a push-button on the toggle is depressed to ensure the strap will not slip during use.
The Allsports USA retainer is suitable for most types of glasses and sunglasses.
