I am writing about the Cougar Optics Harness. It acts like a regular camera strap but holds the camera or binoculars much more securely. The straps cross behind the back to distribute weight more evenly and provide more comfort than a simple neck strap. The official website states that the harness keeps the camera or binoculars from being jostled, such as would frequently happen on a hike. Right now, it is being offered online for an inexpensive $17.95 or $19.95 for the newer design. S&H is completely free.
