I have tried several bino bras but found them too difficult when shedding/adding layers, especially while wearing a backpack. On the other hand I never liked that my binoculars flopped, sometimes onto my rifle scope. Or, if you have to crawl during a stalk, your binos are dragging the ground. After seeing Jaycee's comments above, I watched the video from Rick Young Outdoors about their Ultra-Light Bino Harness. That harness looks like the perfect solution for me. I had to order one, especially for the price $20. The video is here:
