Black elastic strap with metal attachment clips at each end. These were fitted to the Irvin using the small brass 'eyes' sewn onto the rear of the collar. Often referred to as spare goggle straps but were in fact used to help pull the collar into the upright 'stand' position. The elastic is in very good order bar minor soiling and wear. Both connectors and adjuster slide are excellent. An excellent used example. Remarkably difficult to find. Beware of copies! Stock code J22779.
