This is a very comfortable to wear and practical sunglass retention cord that fits easily onto glasses. The neoprene backing moulds easily to the back of the neck if the glasses are taken off the face. If you are near or over water, the cord will provide enough buoyancy to hold up the glasses and to stop them sinking. The length of the cord can be easily adjusted.
