Here's a comfortable way to carry your binoculars for hours. When comfort is key, you can lighten your load with the Vortex Harness. The Vortex Binocular Harness Strap spreads the weight of binoculars and cameras across your upper back and shoulders to eliminate neck strain. The harness strap keeps your binoculars from swinging as you stride along. Nylon/Lycra straps are durable and allow for easy sliding of binoculars into viewing position and a one-size-fits-all design is easy to attach and completely adjustable allowing you to move your binoculars or camera up and out as needed.
