For those who prefer a longer strap, the binocular neck strap extension is an adjustable expansion option for your binocular neck strap. Similar to all of our binocular carrying systems, they are designed to work with our unique loop attachment system. This enables the strap to quickly snap into place using our quick disconnects, which are included in both the neck strap and binocular harness and are interchangeable for a quick swap out. -14 inch total length extension
