Our binocular lens cap retention cord is designed to extend your stock lens cap’s retaining strap. This kit will allow you to adjust your cover so it hangs below your face in a comfortable placement. This also prevents your exhalation breath from bouncing off the cap and fogging up your binocular eye pieces. The elastic cord comes 12” long and you can cut it to your desired length. The hardware used to cap the cord is a reusable item.
