This lightweight croakie is handmade from durable saddle leather. The unique adjustable swivel fasteners at the end accommodate all sizes of glasses and swivel 180 degrees allowing for great comfort and adjustability no matter the size or type of sunglasses. The rubber ends tighten so that your glasses will remain securely strapped to your head. Our leather croakies also feature an adjustable slider, stretching the croakie out all the way to a fully extended 34 inches for a loose and relaxed fit. They can also slide back in to its 20 inch secure fit. Our croakies are handmade with premium industrial grade hardware and are hand dyed in a variety of colors. Handmade in the USA, from American leather.
