Friend of mine has the S4 gear lockdown
https://goo.gl/ZMLq3L binocular harness, and thinking to get one as well. I've done some research and this binocular harness seems to have the best quality on the market
One comment though, for hunting, wild life photo, etc. Make sure to paint in black or dark green all those orange and white markings on the harness. That's the only default I can see
