Black elastic strap with metal attachment clips at each end. These were fitted to the Irvin jacket 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. This example is a bit worn and faded, but does retain some elasticity. Minor tarnishing on the connectors and adjuster slide. Remarkably difficult to find. Beware of copies! Reasonable / quite good used condition. Stock code J25402.
