These neck straps permit you to position your binocular on your chest, rather than bouncing awkwardly on your stomach. by using a wide neck strap you can spread the weight of your binocular over a much wider region. The advantage of using such a neck strap is that these straps to a great extent reduce the apparent weight of your binocular so that you can observe and enjoy viewing all day without neck pain. A binocular neck strap is normally light weight and easily washable.
